GLACIATED GRANITE LANDSCAPE
One of the world's most famous mountain landscapes, the Yosemite
Valley. More than 3000' (900m) deep, the valley has been carved
out of the granite rocks of California's Sierra Nevada mountain
range by the combined action of rivers, glaciers and many other
processes of WEATHERING and EROSION. The main valley, once formed
by a river, was enlarged by the passage of a glacier during recent
GLACIAL PERIODS. The glacier steepened the gentler valley-side
slopes to leave towering cliffs, HANGING VALLEYS, WATERFALLS,
GLACIAL LAKES and a host of other features. Yosemite is particularly
famous for its GRANITE DOMES among which HALF DOME, seen here
on the left, is the most famous.
