The sustained grandeur of the High Sierra is strikingly illustrated by the great height of the passes. Between latitude 36 deg. 20' and 38 deg. the lowest pass, gap, gorge, or notch of any kind cutting across the axis of the range, as far as I have discovered, exceeds 9000 feet in height above the level of the sea; while the average height of all that are in use, either by Indians or whites, is perhaps not less than 11,000 feet, and not one of these is a carriage-pass.
