With Shawn. Part of a 3 day weekend during which I also climbed Pt 13,660A and Pt 13,577 (Sangres) on Friday, and Sayre's Benchmark with 13,460 on Saturday.
From the Taylor Reservoir side with Prize Benchmark and "Petroleum Peak".
Climbed a random couloir with Brendan James for a fun day out. Didn't know the peak or the route til we got home and looked at Google Maps. Had intended to climb Grizzly Peak that day.
With Katie, 15, from Anderson Lake TH. Larson-Petroleum-Anderson. Grand day out! Met a surprisingly tame fox on the ridge.
Loop hike from Anderson Lake Trailhead - up Larson, over "Petroleum", "Anderson" and Prize BM then hiked back down the valley to the TH.
It was cloudy at dawn and early morning hours but then turned out to be a perfect sunny day.
