East Face, Class 2
The Climb
From Blackstone-Grasmere Road, bushwhack southwest then west through grass and tumbleweeds, crossing knolls and gullies. Climb up a final shoulder/face to reach a high ridge. Head left/south on this narrow, grassy ridge then right/west to the high point of Horse Hill. The summit has a metal post and two USGS benchmarks atop it. This bushwhack requires lots of ups and downs and endless tumbleweeds that will tangle up your feet/boots. Be patient. When you first see the hill, it appears a long ways off but the terrain goes faster than you expect. The summit of Horse Hill is the southernmost of several high ridge points as the USGS map shows.
