Ascent Trip Report

By the time I got back from Gibbs a little before 9am, everyone had woken. And plans had changed. Instead of doing a short 4-5mi trip, some were headed out to do some rock climbing and others were going to just hang out at a lake for the afternoon.

Heyning and Shirley, who had carpooled with me, were of a different mindset. They wanted to do a solid day trip before leaving for the Bay Area. I felt fine despite having just done Gibbs an hour earlier, so I joined in their mindset and suggested we try Mammoth Peak nearby. Heyning had done it some winter years past on an overnight from the north side. Looking at the topo, Mammoth's east face looked promising.

Not sure if this route is ideal or not. More direct routes are I'm sure out there. We only had a topo to go by, and we didn't want to try a possible shortcut and end up stuck at a wall somewhere.

From Mono parking lot, take the Mono trail down 2.25mi to the junction for the Spillway Lake Trail. Cross the Parker Pass Creek. Continue southeast for 1mi. At around 1mi, you'll come to a small ridge with a gully on its west side going north-south. Go up and over the ridge into the gully. Follow the gully up for a quarter of a mile to a plateau. Enjoy the next flat half mile, aiming towards the 30 degree boulder slope to the southeast at 10760ft. After that last flat part, it's 1350ft of constant boulder climbing to the top. In general, the route finding is easy pickens. Pick whatever line looks best to ya at 11050ft, and continue west/northwest to the top of the rocks.

On a personal note, I'm super thankful for having been able to share this route with Heyning and Shirley. They're both great company with positive attitudes, which was crucial when a hard fatigue hit me at 11500ft. Shirley at that point caught up to me right as I was finishing some food. "Man, I'm exhausted. If it was just me up here it'd be tempting to lay down, nap, and wait for you two here..." Shirley: "Well. You did do 3000ft gain this morning before this hike. But remember if u don't finish this peak today you know you will have to come back again." That thought did not appeal to me; her inspirational words hit the spot. Thanks, Shirley!
