Mountain which rises steeply from the northeastern shore of the 
lake is about 4000 feet altitude. Mt. Hanna, often called 
‘Bottle Glass Mountain’’ from the quantity of obsidian found 
upon it, is some distance away from the lower end of the Lake, 
on the western side, and its elevation is considerably less. The 
plants of the Sierra Nevada found on these mountain tops differ 
somewhat, in most cases, from those of the original locality, a 
difference easily to be explained by their isolation and difference 
of the soil. Micromorphic botanists may indeed insist that the 
differences between these plants found on the massive granite of 
the Sierras and those on the many-colored shales of Snow Moun- 
tain are sufficient to constitute species.
