Mount Observation is a summit of 5207' near Leadville.
An Improved Topographical Map of the Northern & Middle Mines. Compiles from the most recent & authentic Surveys, showing a practicable Route for the great Atlantic & Pacific Rail-Road, through the Sierra Nevada at Fredonyers Pass. With a faithfull delineation ... (1854) shows what appears to be Ladder Canyon?
The print version of the above describes a letter from Milleson that appeared in the April 30 1855 Sacramento Daily Union titled "Fredonyer's Pass-A Description of the Mountains in that Region by Dr. Fredonyer.":
"Being weary of proceeding so far to the northward part of the company and myself determined to take a direct west course as possible, and force a passage over the Sierra Nevada at any point rather than make the great circuit by Lassen's Pass. For this purpose we pursued our journey up the Canon Valley, near a SW direction, over a sterile but interesting district, covered with innumerable little pieces of obsidian of different colors; about midway in the valley we passed through a volcanic causeway varying from one to two hundred feet in width and over a mile in length, with perpendicular walls fifteen feet high. The valley on the north and western sides is lined by a ridge of basaltic cliffs, increasing in height and grandeur until they reach the head of the valley at Ladder Canon, and sixteen miles distant from the mouth of High Rock Canon.'
"To the south of Ladder Canon lies Mount Observation, rising to an elevation of nearly three thousand feet above the planes of the interior basin of a conical shape, the summit and flanks entirely destitute of vegetation. "
The legend for Valley of the Mud Lakes (1861) mentions Mount Observation.
Mount Observation is cited as being in the State of Nevada 1914 map (see below), but, like Ladden Cone, it does not appear in that map. Ladden Cone and Mount Observation have sequential GNIS numbers.
Mount Observation does not appear in the Division Peak (1980) map, though it does appear in the Division Peak (2018) map.
Earthpoint has the location at S11 T37N R23-1/2E
