Some say the world will end in fire,
Some say in ice.
From what I’ve tasted of desire
I hold with those who favor fire.
But if it had to perish twice,
I think I know enough of hate
To say that for destruction ice
Is also great
And would suffice.


By American poet Robert Frost (1874-1963), first published in Harper’s Magazine 1920.

Tongariro National Park is situated in the southern part of the North Island of New Zealand, centered around three active volcanoes, Ruapehu (2797 m), Ngauruhoe (2291 m), and Tongariro (1978 m). This park, which covers 786 km2, was established as early as 1887, thus being among the oldest national parks in the world. For the major part of the year, the higher areas of the park are covered in snow.

In fact, Ruapehu is a name that includes a number of peaks, of which the tallest is Tahurangi (2797 m), whereas a striking pointed peak is Girdlestone (2658 m). Initially, this mountain was named Little Matterhorn Peak by Hubert Earle Girdlestone (1879-1918), a New Zealand explorer and war hero, who was killed in France in 1918. His friends installed a plaque on the mountain in 1922, renaming it Girdlestone Peak.

Junipers (Juniperus) are conifers of the cypress family (Cupressaceae), comprising between 50 and 67 species, depending on authority. These trees and shrubs are widely distributed throughout the Northern Hemisphere. This genus is described on the pages Plants: Plants in folklore and poetry, and Plants: Ancient and huge trees.

Drooping juniper (Juniperus recurva) is native to the Himalaya, from northern Pakistan eastwards to the Yunnan Province, south-western China, growing at altitudes between 1,800 and 4,600 m. The specific name is from the Latin recurvo (’bent backwards’), like the common name referring to the drooping branches.

Foliage and wood of this species are burned as incense at Buddhist and Hindu shrines, and near the Pangboche Buddhist Monastery in Khumbu, eastern Nepal, is a sacred growth of this tree, depicted on the page Religion: Animism.



These branches of drooping juniper are covered in newly fallen snow, between Tharepati and Melamchigaon, Langtang National Park, central Nepal.




In the 1980s and 1990s, I spent several winters on the island of Vorsø, a nature reserve in Horsens Fjord, Denmark. During these stays, I could enjoy a number of very beautiful impressions. Below, a collection of winter pictures from this interesting reserve is presented. Others are shown on the page Nature Reserve Vorsø.

In severe winters, each falling tide leaves a thin layer of frozen saltwater on emerging stones. The following rising tide will press this layer outwards, leaving a new thin layer of ice inside the previous layer. In this way, several rising and falling tides create a ’flower’ with delicate ice petals. (Photo copyright © by Kaj Halberg)

In Taiwan, ice-covered roads are a rare phenomenon, only occurring in the highest mountains in the central part of the island. As ice on the roads is so rare, it is not customary to strew salt, and drivers have difficulty passing the oce-covered parts.

In January 2020, my friend Niels Andreasen and I passed an ice-covered part of the road leading up to the high mountain Hohuan Shan. Several cars were stranded here, as the drivers had no experience with such roads, and they speed up far to much to pass.

Snowdrop (Galanthus) is a genus of c. 20 species in the amaryllis family (Amaryllidaceae), most of which are native to the Balkans, the Near East, the Caucasus, and the Alborz Mountains of northern Iran. One species, the common snowdrop (G. nivalis), is found from northern Spain and western France eastwards to Ukraine, but has become naturalized elsewhere in Europe and in parts of North America.

The generic name is from the Greek gala (‘milk’) and anthos (‘flower’), referring to the white flowers of the genus, whereas the specific name nivalis (‘of the snow’) refers to the early flowering of common snowdrop. The name snowdrop first appeared in 1633, in the book Great Herball by English herbalist John Gerard (c. 1545-1612). (In the first edition of his book, Gerard had named it the timely flowring bulbus violet.) The word snowdrop may be a translation of the German word Schneetropfen – a type of earring, which was popular in those days. Other common English names include February fairmaids, dingle-dangle, Candlemas bells, Mary’s tapers, and, in Yorkshire, snow piercers. (Sources: M. Bishop, A. Davis & J. Grimshaw 2002. Snowdrops: A Monograph of Cultivated Galanthus. Griffin Press, and R. Mabey 1996. Flora Britannica. Sinclair-Stevenson)

An old legend relates that when Adam and Eve were expelled from the Garden of Eden, they experienced dark and cold for the first time, and Eve sat down on the cold ground and wept. An angel appeared before her, caught a snow flake in his hand and blew on it. The water drop fell to the ground, and a snowdrop appeared. This gave comfort to Eve, who began to have new hope.

Common snowdrop is one of the first harbingers of spring, often appearing before the winter snow has disappeared. It is cultivated everywhere in northern Europe and often escapes, in this case in Nature Reserve Vorsø, Horsens Fjord, Denmark. (Photo copyright © by Kaj Halberg)




Spring snowflake (Leucojum vernum) resembles common snowdrop, but has wider, bell-shaped flowers with a yellowish-green spot on each petal. Formerly, the genus Leucojum contained 11 species, but in 2004 nine of these were moved to the genus Acis. Today, only L. vernum and L. aestivum remain in Leucojum. The generic name is derived from the Greek leukos (‘white’) and ion (‘violet’).



Spring snowflake is also widely cultivated, here on the island of Funen, Denmark. (Photo copyright © by Kaj Halberg)




If you walk around the Annapurna Range, central Nepal, you must cross over the pass Thorung La (5415 m). People in this area are mainly Buddhists, and the peak of this pass is marked by a chorten (a Tibetan variety of the stupa) and vividly coloured prayer flags.

Chortens, prayer flags, and other Buddhist subjects are described in depth on the page Religion: Buddhism.

The snow leopard (Panthera uncia) lives in mountains of Central Asia, but has been hunted to extinction in many areas because of its rich and beautiful fur. In Buddhist areas of the Himalaya, hunting is banned, and in these areas this rare cat has safe havens, where it can prey on species like bharal (Pseudois nayaur), urial (Ovis vignei), Himalayan tahr (Hemitragus jemlahicus), and Himalayan musk deer (Moschus chrysogaster).

The black Eurasian coot (Fulica atra) is a member of the large family Rallidae, comprising coots, gallinules, rails, crakes, and many others. As a breeding bird, it is widely distributed across Temperate Eurasia, eastwards to Japan, and in north-western Africa, the Indian Subcontinent, New Guinea, and Australia. Siberian populations are migratory, whereas African, Indian, Australian, and most European birds are resident. Very similar species are found in the Iberian Peninsula, Africa, the Americas, and Hawaii.

Rhododendron arboreum is the largest among c. 100 species of rhododendron in the Himalaya, growing to 15 m tall. It is very common, and in March-April, when it is flowering, parts of the forest show a reddish or pinkish tinge, stemming from millions of flowers. The intensity of the red colour of the flowers decreases, as you move higher, and near the upper limit of its distribution, you sometimes encounter trees with white flowers. This tree is the national plant of Nepal, called lali guras (‘red rhododendron’).

The specific name of the bell rhododendron (Rhododendron campanulatum), from the Latin campanula (‘little bell’), refers to its bell-shaped flowers. This attractive shrub is very common in the Himalaya, forming dense thickets at altitudes between 2,800 and 4,000 m. One of the characteristics of this species is the rusty-coloured layer of hairs on the underside of the leaves.

The Barun Valley is an alpine valley, situated in Makalu-Barun National Park, which covers an area of c. 1,500 km2 in northern Nepal. To the west, this park borders Sagarmatha National Park, covering 1148 km2, to the north the huge Qomolangma Nature Preserve in Tibet, covering c. 35,000 km2, and to the south a buffer zone, covering 830 km2. Thus, the valley is situated in the heart of a very large protected area.

In spring 1991, together with Lars Nørgaard Hansen, I undertook a very interesting hike to this valley, related on the page Plants – Plant hunting in the Himalaya: The rhododendron valley.

The snow goose (Anser caerulescens) comes in two colour morphs, a snow-white phase, which has given this species its common name, and a bluish-grey phase, referred to as ‘blue goose’, which has given it the specific name caerulescens, meaning ‘bluish’.

The snow goose is a bird of the New World, breeding mainly in northern Canada and Alaska, with small populations in Greenland and north-eastern Siberia. It spends the winter along the Pacific coast, from southern British Columbia southwards, and also in southern United States and Mexico.

Poplars (Populus), also called aspen or cottonwood, of the willow family (Salicaceae), are a genus of anywhere between 25 and 35 species of trees, some of which are indeed majestic, growing to 50 m tall, and with a trunk diameter up to 2.5 m. Poplars are deciduous, and several species display brilliant yellow foliage in the autumn. Some examples are shown on the page In praise of the colour yellow.

Poplars are native to the major part of the Northern Hemisphere, from subarctic areas southwards to Mexico, North Africa, Iran, the Himalaya, and China.

The Canadian poplar (Populus x canadensis) is a hybrid between black poplar (Populus nigra), which is native to Europe, south-western and central Asia, and North Africa, and eastern cottonwood, or necklace poplar (Populus deltoides), which is native to the United States, south-eastern Canada, and north-eastern Mexico. This hybrid is very commonly planted around the world, often along roads.

In spring and autumn, the Rohtang La Pass (3978 m), Himachal Pradesh, northern India, is a very popular destination for Indian tourists, and below the pass, numerous dhabas (small road-side restaurants) have sprung up helter-skelter. Also, woollen hats and other warm clothes are sold to the lowlanders who are very sensitive to cold.

The snowy egret (Egretta thula) is named after its snow-white plumage. This small heron, which is very similar to the Old World little egret (E. garzetta), is found in South and Central America, and also in parts of North America, where some populations are migratory, wintering further south.

The generic name is from a French word, aigrette, meaning ‘little heron’. In 1782, the specific name, thula, was given to this bird by a mistake by Chilean Jesuit priest and naturalist Juan Ignacio Molina (1740-1829), who didn’t realize that in fact thula was the local Mapuduncun name for the black-necked swan (Cygnus melancoryphus).

The snow bunting (Plectrophenax nivalis) is aptly named, as it breeds in the High Arctic, spending the winter in snowy fields and coastal meadows further south. Its plumage is also predominantly snow-white. This species has a northern circumpolar distribution, with isolated populations in northern Scotland, the Faroe Islands, Iceland, and Cape Breton, Nova Scotia. A close relative, McKay’s bunting (P. hyperboreus), has even more white in the plumage. It is restricted to two small islands in the Bering Sea.

The generic name is from the Greek plektron (‘cock’s spur’) and phenax (‘imposter’, i.e. ‘replacement’). This probably alludes to the shorter claw on the hindfoot of these birds, compared to their close relatives, the longspurs (Calcarius). The specific name is from the Latin nix (‘snow’) and -alis (‘like’), of course referring to the plumage of this bird.

Previously, snow buntings were placed in the bunting family (Emberizidae), but recent DNA research has concluded that they, together with the longspurs, form a separate family, Calcariidae.

Beauty bush (Linnaea amabilis, also known as Kolkwitzia amabilis), of the honeysuckle family (Caprifoliaceae), originates in China, but is widely cultivated for its beautiful flowers. It was described by German botanist Paul Graebner (1871-1933), who named the genus Kolkwitzia in honour of Richard Kolkwitz (1873-1956), professor of botany in Berlin. The specific name means ‘lovely’.

In 2013, following genetic research, it was suggested that Kolkwitzia and other genera should be included in the genus Linnaea, which, until then, contained a single species, the twin flower (Linnaea borealis) – the favourite plant of Swedish naturalist Carolus Linnaeus (1707-1778), also called Carl von Linné. As he was also quite fond of himself, he decided to name this plant Linnaea!

Snowcocks (Tetraogallus) are a group of five large species of game birds, distributed in montane areas from eastern Turkey and the Caucasus eastwards to Central Asia and western China.

The Tibetan snowcock (Tetraogallus tibetanus) is widely distributed in Central Asian mountains, from Tajikistan southeast along the Himalaya to Arunachal Pradesh, and thence northwards through western China to Qinghai, and from there westwards to the Kunlun Mountains. It avoids desert areas of the Tibetan Plateau.

At high altitudes in the Himalaya, yaks burdened with bulky loads are a very common sight. The Latin name of these beasts, Bos grunniens (‘the grunting ox’), is very descriptive, as they grunt incessantly. The females, called nak, yield excellent milk. – The domestication of the yak is described on the page Animals: Animals as servants of Man.

The landscape of Khumbu, eastern Nepal, is an area of very high mountains, including the highest peak on Earth, at 8,850 m, in the West known as Mount Everest, whereas the Nepalese call it Sagarmatha, the Tibetans Chomolangma. Other very tall peaks in this area include Lhotse (8511 m) and Nuptse (7879 m).

One very striking mountain is the double-peaked Ama Dablam (6812 m), which is sacred to the local Sherpa people. In Nepali, the name means ‘mother’s necklace’. The long ridges on either side of the highest peak are likened to the arms of a mother (ama), spread out to protect her child, whereas the hanging glacier on the mountain is likened to a dablam, the traditional necklace worn by Sherpa women.

My late friend John Burke (1951-2010), who joined me on my first hike to the Khumbu, loved Ama Dablam, and he took the striking picture below, depicting Sherpa women, passing in front of the snow-clad peak. Our hike is related on the page Travel episodes – India & Nepal 1978: Journey towards Everest.

In 1984, the mute swan (Cygnus olor) was elected the national bird of Denmark – an appropriate choice, as it is very common. This was not always the case. In the 1800s, swans were hunted in Denmark, and by 1920, only three or four pairs were breeding in the vicinity of Copenhagen. Swans were protected in 1926, and the mute swan soon began spreading across the country.

In his fairy tale The Ugly Duckling, Danish poet Hans Christian Andersen relates the fate of a cygnet, which is ostracized by its fellow fowl in a farmyard, where it has been hatched together with ducklings. It has to undergo much suffering, before it realizes that it has matured into a beautiful swan. In reality, this story is about the fate of Andersen himself.

The mute swan is native to northern Europe, from southern Norway and southern Finland, southwards to southern France and Romania, and from Ireland eastwards to western Russia and Ukraine, and with patchy breeding occurrence in the Balkans, Turkey, and Central Asia, eastwards to southern Siberia, Mongolia, and northern China. It has also been introduced elsewhere, including North America, Australia, New Zealand, and South Africa.

As opposed to the other northern European swans, the whooper swan (C. cygnus) and Bewick’s swan (C. columbianus ssp. bewickii), the mute swan is not very vocal, hence the popular name mute. The name Cygnus is a Latinized form of the Greek kyknos (‘swan’), whereas olor is Latin, also meaning ‘swan’.

The winter is a hard time for these birds, and in severe weather conditions, many succumb to cold and starvation.

Mount Taranaki is a dormant volcano on the west coast of the North Island, New Zealand. This striking mountain rises to a height of 2,518 m from the surrounding lowland. It was named Taranaki by the Maori, from the words tara (‘mountain peak’), and, presumably, ngaki (‘shining’), alluding to its snow-covered peak.

Until recently, the official name of this mountain was Egmont, thus named by British explorer and captain James Cook (1728-1779), in honour of John Perceval, 2nd Earl of Egmont (1711-1770), who, as former First Lord of the Admiralty, had supported the search for Terra Australis Incognita.

Common mare’s tail (Hippuris vulgaris) is a striking plant, growing in shallow freshwater. It is distributed in northern Eurasia, southwards to the Himalaya, northern China, and Japan, in Greenland, and in northern and western North America, southwards to California, New Mexico, Illinois, and New England.

The generic name is from the Greek hippos (‘horse’) and oura (‘tail’), thus horsetail. In English, it is also sometimes called horsetail, although this name is usually reserved for species of the genus Equisetum. Previously, Hippuris was the only genus in the family Hippuridaceae, but has now been moved to the plantain family (Plantaginaceae).

Common mare’s tail is utilized in herbal medicine for treatment of wounds, stomach ulcers, and internal and external bleeding.

The common butterbur (Petasites hybridus) is native to southern Europe and western Asia, but has become naturalized in northern Europe and North America.

This plant has both male and female plants, and female plants were given the name Tussilago hybrida by Swedish naturalist Carl Linnaeus (1707-1778), as he thought they were a hybrid between the male plants and white butterbur (P. albus). In northern Europe, female plants are very rare, and almost all populations are clones of male plants.

The generic name is derived from the Greek petasos, meaning ’broad-brimmed hat’, like the common name umbrella plant referring to the very large leaves, growing to one metre across. These leaves appear in two of Hans Christian Andersen’s fairy tales, The Ugly Duckling and The Happy Family. The name butterbur supposedly stems from the habit of using the large leaves to wrap butter in during hot weather, whereas another popular name, lagwort, refers to the late appearance of the leaves, which do not usually unfold, until the flowers have faded. ‘Dock’ is a term applied to various plants with large leaves, here used in the popular names flapperdock, blatterdock, and butterdock.

Snowfinches (Montifringilla) are a small genus of eight high-altitude passerines, mainly distributed in Central Asia. A single species, the white-winged snowfinch (M. nivalis), is found further west, through the Middle East to the Alps and the Pyrenees. Despite their name, snowfinches are not finches, but sparrows, of the family Passeridae.

The snow plant (Sarcodes sanguinea) is a parasitic member of the heath family (Ericaceae), which derives its nutrients from underground fungi. It is distributed from the Cascade Range of Oregon, southwards through montane areas of California to northern Baja California, Mexico.

American botanist, chemist, and physician John Torrey (1796-1873) found the colour of this plant so striking that he named it Sarcodes sanguinea, from the Greek sarkos (‘flesh’) and the Latin sanguis (‘blood’), thus ‘the blood-coloured fleshy one’. The common name refers to the early flowering of this species, which often appears, when snow is still covering the ground.

The goat willow (Salix caprea) is a smallish tree, which is native to almost all of Europe, the Caucasus, and parts of Central Asia. As opposed to most other willow species, goat willow thrives in forests, but is far more beautifully developed in open land, where it often becomes a tree with several trunks, to 15 m tall.

Especially beautiful are the male trees in spring, when they display thousands of golden-yellow catkins, which are much visited by bees and bumble bees, as the goat willow is among the earliest suppliers of nectar and pollen. An old Danish name of the species was palm willow. In the days, when people in Denmark were Catholics, flowering branches of goat willow were utilized to adorn the churches on Palm Sunday.

Previously, this species was utilized for numerous purposes. The foliage was a good animal feed, and even today it is utilized as fodder for sheep and goats in certain parts of Norway. The thinnest branches were made into various items, including fish traps and baskets. Today, branches of osier (Salix viminalis) are used, as they are more suitable. Due to the light and tough wood, slightly thicker branches were made into tool handles and fences, the trunk into e.g. furniture.

Wicks were made from the seed hairs, which were also stuffed into quilts and also used as lining in coats. The bark contains tannins and was formerly used for tanning of animal hides. The bark also contains a glycoside, salicin, which was previously used as a febrifuge in the form of salicylic acid, which is today produced chemically.

Most of these old utilizations have today gone out of use. One particular usage takes place in the Viking Ship Museum in Roskilde, Denmark, where pegs for the reconstruction of viking ships are made from goat willow wood.

In 1976, an area of 1,710 km2 in central Nepal, comprising the Langtang Valley, the Gosainkund Lakes, and the area north of these lakes, to the Tibetan border, was declared a national park, named Langtang National Park. Altitudinal variation in the park is tremendous, from 792 m above sea level along the Trisuli River, to the peak of the highest mountain of the area, Langtang Lirung (7245 m).

No less than five vegetation zones are represented in this park: subtropical, lower temperate, upper temperate, subalpine, and alpine, containing large tracts of forest, comprising species of oak (Quercus), maple (Acer), Rhododendron, Himalayan birch (Betula utilis), Himalayan silver fir (Abies spectabilis), Himalayan hemlock (Tsuga dumosa), blue pine (Pinus wallichiana), and others. These forests are home to several threatened animals, including snow leopard (Panthera uncia), red panda (Ailurus fulgens), and a gorgeous pheasant, the satyr tragopan (Tragopan satyra).

The Gosainkund Lakes, comprising altogether 54 lakes, are all sacred to Hindus. Every year, during Full Moon in July or August, thousands of devout pilgrims undertake the demanding hike to these lakes to have a cleansing bath in their icy waters. Orthodox Hindus wish to bathe in all 54 lakes.

My adventures in this area are related on the pages Travel episodes – Nepal 2009: Across a snow-covered pass, and Plants – Plant hunting in the Himalaya: Around sacred lakes of Shiva. Hinduism is dealt with in detail on the page Religion: Hinduism.

Snowberry (Symphoricarpos albus) is a native of North America, but has been introduced as an ornamental to many other parts of the world. Formerly, indigenous American tribes utilized the leaves as a poultice on cuts and other wounds. A mild extract of the bark was used in cases of coated tongue in children.

Firs (Abies) are a genus of c. 50 species of conifers, mainly growing in montane areas across Eurasia, North Africa, and much of North and Central America.

The Himalayan silver fir (Abies spectabilis) can grow to very large proportions, to 50 m tall, with a trunk up to 1.5 m across. This species is very common in the Himalaya, found from Afghanistan eastwards to Myanmar. It is widely used locally, its wood for construction, carpentry, furniture, paper-making, and firewood. The foliage is utilized medicinally for asthma, bronchitis, colds, and rheumatism, and is also burned as incense.

The Pasterze is a glacier beneath Grossglockner (3798 m), the highest mountain in Austria. With a length of about 8.4 km, it is the longest glacier in the eastern Alps. Although still impressive, it has been decreasing at an alarming rate in later years. It retreats about 50 m every year, and its volume has diminished by half since the first measurements in 1851.

The common eider (Somateria mollissima) has an almost circumpolar distribution, found along Arctic and Northern Temperate coasts, from the Kola Peninsula westwards across Scandinavia, the northern British Isles, Iceland, Greenland, Maine, Arctic Canada, and Alaska, to the extreme eastern Siberia.

The nest of this species is built near the seashore, lined with down, which the female plucks from her own breast. This soft down has been harvested by people for hundreds of years, used as filling in pillows, quilts, and jackets. This harvesting was done with no harm to the birds, as it took place when the ducklings had left the nest.

The scientific name is derived from the Greek soma (‘body’) and erion (‘wool’), and the Latin mollissimus (‘very soft indeed’), all referring to soft down feathers. The name eider is a corruption of the Icelandic name of the bird, æðarfugl, which is derived from the Old Norse æðr.

In Northumberland, southern Scotland, the eider duck is known as the cuddy duck, named after Saint Cuthbert (c. 634-687), a monk, bishop, and hermit of the early Northumbrian Celtic church. While on the Farne Islands, he instigated special laws to protect the ducks and other seabirds, nesting on these islands.

Snowbells, of the genus Soldanella, comprising about 15 species, are found in montane areas of southern Europe, from the Pyrenees eastwards to the Balkans. The common name snowbell refers to the early flowering of these plants, which often appear in depressions, shortly after the snow has melted. The generic name Soldanella is a diminutive of the Italian word soldo (‘coin’), thus ‘little coins’, referring to the leaf shape of most species of this genus.

Dwarf snowbell (Soldanella pusilla) is found in the Alps, the Carpathians, the Apennines, and in mountains of the Balkans. Other species of snowbell are described on the page Plants: Flora of the Alps and the Pyrenees.
