Original: Peter Doggett, December 2007

DRIVING ROUTE 1

  • Take I-10 east past Banning to the intersection with SR 62.
  • Go north on SR 62 to Park Road in the town of Joshua Tree with a sign "Joshua Tree National Park". Turn right.
  • Drive 16 miles on this road to the intersection with the Keys View Road. Turn right.
  • Continue 4.3 miles (1.8 miles past the Lost Horse Mine Road) to a parking turnout on the left.
  • DPark here. Room for 3 to 4 vehicles.

HIKING ROUTE 1

  • From the parking area (4850'), walk back down the paved road for about 1/4 mile.
  • Leave the road on the right and proceed east for 0.9 miles to a shallow saddle at 4760'.
  • From this shallow saddle, drop down 60' to a wash at 4700'.
  • In the wash, turn right and proceed 100 meters to a large gully.
  • Go east up this gully to a plateau at 5000' that is about 0.5 miles west of the summit.
  • Continue east for 0.4 miles to the summit plateau at 5280'.
  • Turn right (SE) and proceed about 50 meters to the summit.

Note: One can avoid the saddle at 4760' by walking around the southern bump. This will only save about 20' of elevation gain and will result in an extra 1/4 mile of hiking distance.


NOTES

The restored buildings of the Lost Horse Mine add a point of interest to this hike. The old stamp mill is fenced off due to an accident in the early 1990's.

The region consists of open desert terrain, so many cross-country routes are possible. The peak has been climbed from Malapai Hill on the east and also by following the pipeline that connects Ryan Campground on the north with the Lost Horse Mine.
