  1. Don't be confused about the true highpoint of Glass Mountain. There is a peak with a radio repeater station on its top about 0.75 miles NW of the summit. This peak is called Glass Mountain on the 1986 Provisional Edition 7.5 minute series topo but is shown to be 17 feet lower than the true summit.
  2. Glass Mountain got its name for the vast obsidian (volcanic glass) deposits found on its slopes. Large specimens of both brown and black obsidian can be found on the slopes just to the S of the climbing route at about the 9600 foot elevation level.
  3. The Sawmill Meadow Campground mentioned in the DRIVE/EASTERN APPROACH directions abovehas a few campsites with picnic tables, making it a convenient place to camp when doing Glass Mountain.
