Papoose Lake – Trinity Alps

Originally Published on 12/2/2008 

The day after Thanksgiving was dedicated to working off some calories. I woke up at 5AM and took off to Hobo Gulch Trailhead on the edge of the Trinity Alps Wilderness. After 14 miles of hiking, including a scramble at the end, Papoose Lake was achieved around 2PM. I spent the afternoon exploring the frozen lake and surrounding areas; settling down for a cold night I started a fire and cooked some gourmet sausages. Saturday morning I awoke — after a surprisingly warm night — to a thawing lake, 2 cups of coffee, and a glorious sunrise. I packed a day bag and climbed the southwest ridgeline.

The geological character of the lake is fascinating in that the southwest edge is a fault where granite — common in the high Trinity Alp — meets a serpentine rock type (more geology) also typical across northwest California; scattered in many of its mountain ranges. This trip was originally planned because my favorite conifer, the foxtail pine, favors serpentine outcrops at high elevations — I had wanted to get into this region of the Alps and search out some foxtails. Here I had elevation and serpentine — so I predicted that there would be a new grove of this rare tree for me to discover just on the south-face above the lake. Upon achieving the ridge, my hunch was correct. While, foxtail pines do grow on granite in the high Trinity Alps they are much more common, and groves more extensive, on serpentine.

Serpentine meets Gabbro.

I spent a glorious day exploring an exceptional forest of trees — growing with foxtail pines were whitebark pines, Shasta red firs, mountain hemlocks, and a few Brewer spruce. In the cirque that holds Papoose Lake there are 11 species of conifers. Along the entire trail one can identify 15 species. My final day, Sunday, I returned to the truck refreshed and exuberant.

I revisited this lake in September 2023. Read my new thoughts, 15 years later, here.

I try to get to Papoose every few years — one of my favorite Trinity Alps lakes. I’ve climbed the southwest ridge myself — whenever I cross-country from Papoose to the Russell Cabin Trail — that’s how I go. It’s a short but steep and very brush off-trail route. (The Russell Cabin Trail connects with the main North Fork trail at Backbone Creek just a short distance from the Hobo Gulch Trailhead.) —–

COMMENT: AUTHOR: Michael E Kauffmann EMAIL: michael_kauffmann@yahoo.com URL: DATE: 5/17/2014 2:24:27 PM Stephen- from Papoose Lake it is a significant climb to get to the foxtails. They are on the south-facing ridge, south of the lake. They may be north of the lake as well, but I did not climb into that area. South of the lake, as you see in the blog, is serpentine. The foxtails love this soil type and it is quite a spectacular stand here. They extend down slope from the ridgeline to an elevation I could not verify since I stayed high on this trip. Generally, foxtails in the Klamath Mountains live above 7,200′ but can be as low as 6,600′ depending on habitat. If you search them out – let me know what you find.
