LANDS OF PERPETUAL snow

A recent writer made the mistake ck
referring to oil arctic lands ~ tucked
In under their everlasting blanket Of
snow" We know, however. of NO land
area lying near the sea level that 10 per-
petually covered with snow, says q Chi.
cago paper.
Mr.. Peary, the only visitor to the most
northern land yet discovered, found
flowers and grass there, and killed arctic
game that had fattened on the heritage
Of the islands lying north OF the ex-
IRENE coasts Of Greenland. Spitzbergen
is one Of the bleakest parts of the world,
yet during the long summer day, when
the sun Is continually above the hori-,
zon, all the winter SHOWS along the
southern valleys melt away up to $500
feet above the sea.
Very little snow can be found in Ice
land in summer, the line Of perpetual
snow being about 1000 feet on the north
ern and 1000 feet on the southern side
of the mountains. Along the coast c:
west Greenland the white mantle of
winter disappears in summer and grass
and flowers are found to q height of
1000 feet.
AS for the great arctic plains of the
northern part of this continent they are,
of course, entirely free from snow dur
ing the summer months. Vegetable life
thus has chance in all parts Of the
world. unless the elevation is so high
above the sea that winter polar condi-
tions are maintained the year round.
There are, Of course, lofty elevations,
such as mountains and the ice cap of
Greenland, that are perpetually COW
cred with snow. Geographers have
given much attention to what Is called
the snow line, or the line which marks
the limit of perpetual snow. Its posi-
ton is chiefly dependent upon the sum-
mer temperature and the depth Of the
winter snowfall. The line along which
the sun ceases to melt the snow is the
snow line.
The snow line extends very irregu-
larly along most surfaces because many
mountain valleys. canyons and slopes
are shielded from the sun, and so are
snow covered the year around far be-
low the general snow line This Ia not
the case, however, in tropical regions,
where there is little difference In tenn
perature throughout the year below the
attitudes where frost always reigns.
The result is that in the tropics the sns.w
Tine on the mountains Is a comparative
ly straight line.
OF course the perpetual boundary of
snow approaches neare r to sea level the
farther north or south we 60, from the
tropics. The snow line on Mount. ST.
Elias, in Alaska, is 1900 feet above sea
level, while farther south, in the region
snow line is at an elevation Of $500
feet.
In the Bernese Alps the limit Of per.
petual snow is $500 feet; on Mount
Etna. some hundreds of miles nearer'
to the equator, 1t is 1912 feet: ON Po-
pocatepetl, in Mexico. it Is 1900 feet.
and on Aconcagua, in Argentina. it is
14,800 feet. And as we continue south
the snow line sinks again nearer to the
eS6 10VSA-OsOVV ASc6 at AAo6&Al0u otA0AL6
and $500 feet in TERRA del Fuego.
In the northern hemisphere, where the
southern slopes of the mountains re-
ceive the lions share Of the suns rays,
the snow line lies lower on the northern
slopes. Thus the line of perpetual snow
on the northern slope of Mont Blanc
is about 5000 feet, while on the south-.
ern slope, overlooking Italy, it is 10000
feet above the sea. For this reason the
on the southern than ON the northern
slopes of the Himalayas.
On Mount Kilimanjaro, little south
Of the equator in East Africa, where
| the sun is almost vertical over it, the
snow line on the southern and western
sides is 5000 feet above sea level, while
on the northern and eastern sides it is
over $4,000 feet.
| AS ice melts much more slowly than
snow, many glaciers move down to the
sea, while the snow line nowhere
reaches the ocean. This is the case in
Spitzbergen, Greenland, at Mount St.
Elias, and, in fact, in nearly all lands
within or quite near the polar regions.
In Iceland no glaciers descend lower
than 65 feet above the sea.
In the temperate regions glaciers de-
scend far below the snow line. Thus the
lower limit of glaciers on Mont Blanc is
5000 feet; among the Canadian Rock
les, 5000 feet; on Acancagua, 300 feet.
and on the southern island of New Zea-
land the glacier ends are only $50 feet
above the sea, while the snow line is
| 1900 feet.
But Just as we see plants struggling
for life in almost every crack and crevice
of the rocks, SO the hardest specimens
of vegetation cling to the mountain
sides up to the very limit of perpetual
snow. Life in many forms is very ten
acious, and is bound to exist wherever
there is the slightest chance for it. RE-.
