Note 74 — JOURNAL OF TRAVELS OVER THE ROCKY MOUNTAINS

Dry Creek is still to be found on the maps of Cassia County. Frémont says of this portion of the trail: "All the day the course of the river has been between walls of black volcanic rock, a dark line of the escarpment on the opposite side pointing out its course, and sweeping along in foam at places where the mountains which border the valley present always on the left two ranges, the lower one a spur of the higher; and on the opposite side, the Salmon River mountains are visible at a great distance."
