Jack's Peak (9,856 ft, 3004 m)
is about 120 feet less tall than
Dick's Peak,
its brother peak to the north.
These two peaks are situated in the heart of the
Desolation Wilderness.
They and their adjoining ridges surround
Half Moon Lake
and Alta Morris Lake,
accessible via
Trail 17E31.
From the southeast shores of these lakes glacially transformed granite
croppings descend down to Susie Lake,
where the above picture with the
slant-cone profile of Jack's Peak was taken.
