eaving only small imperfect patches. The lower remnants
of the old glacial surface occur at an elevation of from 3000 to 5000
feet above the sea level, and twenty to thirty miles below the axis of
the Range. The short, steeply inclined canyons of the eastern flank also
contain enduring, brilliantly striated and polished rocks, but these are
less magnificent than those of the broad western flank.
One of the best general views of the brightest and best of the Yosemite
park landscapes that every Yosemite tourist should see, is to be had
from the top of Fairview Dome, a lofty conoidal rock near Cathedral Peak
that long ago I named the Tuolumne Glacier Monument, one of the most
striking and best preserved of the domes. Its burnished crown is about
1500 feet above the Tuolumne Meadows and 10,000 above the sea. At first
sight it seems inaccessible, though a good climber will find it may
be scaled on the south side. About half-way up you will find it so
steep that there is danger of slipping, but feldspar crystals, two or
three inches long, of which the rock is full, having offered greater
resistance to atmospheric erosion than the mass of the rock in which
they are imbedded, have been brought into slight relief in some places,
roughening the surface here and there, and affording helping footholds.
The summit is burnished and scored like the sides and base, the
scratches and strife indicating that the mighty Tuolumne Glacier swept
over it as if it were only a mere boulder in the bottom of its channel.
The pressure it withstood must have been enormous. Had it been less
solidly built it would have been carried away, ground into moraine
fragments, like the adjacent rock in which it lay imbedded; for, great
as it is, it is only a hard residual knot like the Yosemite domes,
brought into relief by the removal of less resisting rock about it;
an illustration of the survival of the strongest and most favorably
situated.
Hardly less wonderful is the resistance it has offered to the trying
mountain weather since first its crown rose above the icy sea. The whole
quantity of post-glacial wear and tear it has suffered has not degraded
it a hundredth of an inch, as may readily be shown by the polished
portions of the surface. A few erratic boulders, nicely poised on its
crown, tell an interesting story. They came from the summit-peaks twelve
miles away, drifting like chips on the frozen sea, and were stranded
here when the top of the mo
