Summit:
W7O/CM-064
Sims Butte can be accessed via the Obsidian trail #3528. This is within a high-use area and requires a $6.00 permit through www.recreation.gov. Hike in about 3/4 mile and turn right off the trail to hike across a log-strewn area to the base of the butte. The butte itself is heavily littered with downed trees and underbrush. It is a tough climb, but fortunately the summit lies only about 500 vertical feet higher. We used an old naked tree to string up the inverted vee antenna.
