On March 28, 2015 I set out to try for the car-to-car FKT on the Pfeifferhorn from White Pine trailhead. On skis I set out on the summer route up Red Pine. I switch to booting with skis on back just before the summit. I reached the summit in 1:27:22. On the descent I opted to skip the scramble and descended into Maybird and then traversed back to Red Pine. I reached White Pine TH in 1:52:13.
