South Thunder Mountain
Created On: Oct 13, 2003

With an elevation of 11,154 feet, South Thunder Mountain is only 4 feet higher than her sister summit of North Thunder Mountain, which is located approximately 1 mile to the north, connected by a long and rugged ridge.

Both South and North Thunder are greatly over looked, with their proximity to the much more popular Lone Peak to the southwest, and the Pfeifferhorn to the east.

Long approaches, tedious scrambling, routefinding, and significant elevation gain ensure that South Thunder is a challenging hike, regardless of the route chosen.

This is a seldomly visited summit, despite the fact that the mountain directly overlooks the Salt Lake valley with a population of over one million.

USGS Quads:
• Dromedary Peak, Utah (1:24k)
• Draper, Utah (1:24k)
• Salt Lake City, Utah (1:100k)
