Location
This HPS peak is the high point of the Ten Thousand Foot Ridge, a string of peaks extending from Lake Peak in the northwest to Hell For Sure Peak in the southeast. It is typically hiked with nearby Lake Peak and/or Grinnell Mountain, all reached from Fish Creek Saddle.
Route 1 ascends the Fish Creek Trail to the saddle then continues to and follows the ridge. Route 2 comes from the South Fork Trail. Route 3 is the route to the old HPS summit, now called Hell For Sure Peak, takes the ridge to that peak from Fish Creek and continues northwest. There are various steep cross country alternatives, which might be useful as descent routes, but we do not vouch for their safety.
