Cosmic Ashtray trailhead (from Spencer Flats/Old Sheffield Road)

want to go

Notes from visits

• • Trailhead for an 8 mile rt hike to see Cosmic Ashtray; trailhead is 5.8 miles down the Old Sheffield Road (generally well maintained but dirt)
  • Hike is very exposed; do in spring or fall
  • Will pass areas of moki marbles on the way to the trailhead
  • Can poke down Big Horn canyon slot (non technical) on the way
  • Can also get to Cosmic Ashtray via Harris Wash trailhead from Hole in the Rock Road (but requires a sandy 4 wheel drive)
