MEMORIAL TO THE PERSONNEL OF THE SECOND FREMONT EXPLORING EXPEDITION
TO OREGON AND NORTH CALIFORNIA.
reports of this expedition directed the migration of the Western
Settlement toward the Oregon Country which hitherto had been merely
a rendezvous for trappers. On December 16th, 1843 the expedition
while enroute from The Dalles of the Columbia to Sutters Fort on
the Sacramento, struggled from the snowy heights of "Winter
Ridge" to the temperate shores of Summer Lake via the canyon
directly west of this spot and bestowed those names which serve
as a permanent reminder of their escape from the snow-bound plateau.
