the basin broad moraine beds have been deposited and on these fine,
thrifty forests are growing. Lakes and meadows and small spongy bogs
may be found hiding here and there in the woods or back in the fountain
recesses of Mount Hoffman, while a thousand gardens are planted along
the banks of the streams.

All the wide, fan-shaped upper portion of the basin is covered with a
network of small rills that go cheerily on their way to their grand fall
in the Valley, now flowing on smooth pavements in sheets thin as glass,
now diving under willows and laving their red roots, oozing through
green, plushy bogs, plashing over small falls and dancing down slanting
cascades, calming again, gliding through patches of smooth glacier
meadows with sod of alpine agrostis mixed with blue and white violets
and daisies, breaking, tossing among rough boulders and fallen trees,
resting in calm pools, flowing together until, all united, they go to
their fate with stately, tranquil gestures like a full-grown river. At
the crossing of the Mono Trail, about two miles above the head of the
Yosemite Fall, the stream is nearly forty feet wide, and when the snow
is melting rapidly in the spring it is about four feet deep, with a
current of two and a half miles an hour. This is about the volume of
water that forms the Fall in May and June when there had been much snow
the preceding winter; but it varies greatly from month to month. The
snow rapidly vanishes from the open portion of the basin, which faces
southward, and only a few of the tributaries reach back to perennial
snow and ice fountains in the shadowy amphitheaters on the precipitous
northern slopes of Mount Hoffman. The total descent made by the stream
from its highest sources to its confluence with the Merced in the Valley
is about 6000 feet, while the distance is only about ten miles, an
average fall of 600 feet per mile. The last mile of its course lies
between the sides of sunken domes and swelling folds of the granite that
