Green plants are considered autotrophs because they photosynthesize—making sugar from water and carbon dioxide. The world of heterotrophic plants is complicated but all have moved away from total energy production from photosynthesis toward obtaining organic carbon either directly from other living beings or through a parasitic relationship with a fungus. Heterotrophic plants include directly parasitic and mycotrophic forms. The conifer forests of the western United States nurture an exceptional diversity of heterotrophic plants.
Part two of whitebark pine negative reports in the Trinity Alps Wilderness
As mentioned in my last post, part of last summer’s whitebark pine conservation assessment and mapping project involved predicting location where the species might occur but was not yet documented. While I found success with some predictions, others turned into negative reports with “ground-truthing.” One negative report was in the Trinity Alps Wilderness around Stonewall Pass, another was in the Foster and Lion lakes region where I based my prediction on the significant landmass above 7,500′.
Part of last summer’s whitebark pine conservation assessment and mapping project involved predicting location where the species might occur but had not yet been documented. While I found success with some predictions, others turned into negative reports with “ground-truthing.” One of these areas was in the Trinity Alps Wilderness around Stonewall Pass where I predicted WBP would occur because there is significant landmass above 7,500′.
The geology of the Stonewall Pass region is built from a majority of mafic and ultramafic rocks. Granite and Gibson peaks are themselves granite, but the remainder of the landscape is composed of serpentine, which makes survival difficult for many species. Interestingly, whitebark pine are found on the serpentine of the Scott-Trinity Mountains around China Peak and Mount Eddy, but it turns out they are absent from the Stonewall Pass serpentines. Whitebark’s absence on the granite of Gibson and Granite peak is most likely due to the size of the inhabitable area offered by the small granite plutons here as well as the increased competition from granite-loving species like mountain hemlock and Shasta fir.
Why, climb Mount Hilton in the Trinity Alps of course.
As I approached the trailhead the car’s outdoor thermometer read 28oF and, with the windows down, the iPod shuffled Rapper’s Delight for my auditory indulgence. I pulled into the large parking lot at Canyon Creek as the lone (semi-domesticated) representative of the human race. Donning hat and gloves, I hoisted my pack and climbed toward what I hoped would be a world-class penthouse suite. With Sugar Hill Gang resonating in my head–as other drift-less tunes have on previous trips–the lyrics seemed preposterously apropos as I progressed toward the named summit (hotel, motel, Mount Hilton…). What five-star resort could possibly compare to a perch on glacially polished granite–surrounded by sky, stars, and wilderness–with a forecast of continued high pressure and a hard freeze? None in my mind.
High above the headwaters of the Salmon River and Coffee Creek, the remarkable ascension of Packers Peak is surprising next to the seemingly superlative granite of the Alps. The peak is a pedestal on which to perch, understand, and enjoy the complex Trinity Alps Wilderness that surrounds you. It is a steep climb from Big Flat, at the end of Coffee Creek Road, to reach this vantage point; but if you are willing to climb the nearly 3,000 feet in just under 3 miles, you will be rewarded.
Gaining an understanding of geology and fire ecology
I had often pondered a high and extensive ridgeline in the middle of the Trinity Alps Wilderness from other mountain top vantage points on which I stood–at one point or another–in my adventures in the Klamath Mountains. It took me several years to realize this jagged range had its own name and many years more to actually get to this isolated place. Finally, in October, I climbed my way into the high country known as Limestone Ridge. I had read this extensive ridgeline (over 3 miles long) was one of the best examples of Karst topography in western North America. This summer, the spectacular Marble Mountain was my first introduction to Karst limestone landscape in the Klamath so I assiduously pursued a chance to see more. With those distant images and arresting words burned on my brain I was finally climbing–up–up–up–from Hobo Gulch in the Trinity River Canyon.
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.
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 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: Stephen Sikes EMAIL: firstname.lastname@example.org URL: DATE: 5/16/2014 1:57:25 PM Hi Michael – I’m curious if you recall the altitude at which the Foxtails began to emerge in the Serpentine soils. Do you recall if you found them below 7000′ at Papoose? —–
COMMENT: AUTHOR: Michael E Kauffmann EMAIL: email@example.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.
