Introduction The guide has been updated from the fieldwork on 14 May 2009 and 11 May 2015, but nothing else on this page has been updated.
This is a guide to the section of the Pacific Crest Trail (PCT) south of SR74 at the extreme eastern edge of Garner / Pine Valley. The trailhead is one mile east of the intersection of SR371 (from Anza) and SR74 at "Paradise Corner", and 0.4 miles west of the Santa Rosa Summit, the eastern edge of Garner / Pine Valley. There is a parking area on the north side of the road, which is signed in both directions along SR74 at a distance of 1000 feet from the turnoff to the parking area.
After parking, cross SR74 and go through the gate in the fence to the signed trail south.
This guide is the result of just two trips in November 2008, and hence is especially incomplete for annuals and perennials not visible at that time of year. Many tentative identifications were made from plants without parts needed for definitive determinations.
See topo map of the trail to mile 5 and its elevation profile.
Highlights of This Trail Some of the highlights of the trail are:
- Seeing cotton-thorn, Tetradymia comosa, in two places along the trail. This is a rare plant in the San Jacinto Mountains, and possibly elsewhere, too. See Plant Species of San Jacinto Mountain: Tetradymia comosa, cotton-thorn.
This is the only species of Tetradymia in the Peninsula Range except for a single location of T. canescens near Monument Peak in the Laguna Mountains. T. canescens is in SnGb and SnBr, and also north to B.C., Montana, Utah. T. comosa is a much more restricted species, only from n L.A. county to n. Baja and "occasional in DMoj".
- Seeing the fantastic view from the knickpoint of the erosion from the Salton Sea, along the escarpments at the margins of Coyote Creek. It was fabulous standing on the knickpoint itself, looking straight down a tributary of Horse Canyon, which is the odd name for the middle part of Coyote Creek.
We could see into the Borrego Desert itself, with the white rocks bordering Collins Valley very prominent, and the Vallecito Mountains beyond the Borrego Springs area on the horizon.
Fig. 1 shows a photograph from the trail as it rounds Lookout Mountain, along with a Google Earth view from above the trail to better show the landmarks.
See also View of the knickpoint from the other side from the point where the trail first touches the knickpoint. For more information about the evolution of this knickpoint from landslides due to erosion progressing up stream from the Salton Trough, see Quaternary landscape evolution in the San Jacinto fault zone, Dorsey and Roering 2006.
We also had great views of Vandeventer Flat, and the Santa Rosa Mountains.
- Seeing the panorama of Garner Valley, the Desert Divide, and the SnJt high country, from a ridge on the west of Lookout Mountain.
- Seeing what the country and plants looked like on the east end of Burnt Valley.
The trail itself traverses a number of distinct terrains, each with its own suite of plant species:
- First is the very head of Garner Valley, a flat sandy area with no trees or large shrubs.
- Second is the north-facing chaparral of Lookout Mountain, with typical north-facing chaparral.
- Third is the south-facing chaparral of Lookout Mountain, with typical south-facing chaparral.
- Fourth is a flat remnant terrain, presumably of the Bautista Formation, in Burnt Valley between two branches of Hamilton Creek. The plants here were completely different, including Opuntia parryi, Encelia actoni, Penstemon centranthifolius, Datura wrightii, and Stephanomeria virgata, instead of the S. exigua deanei found in the rest of the trail.
There are almost no bedrock outcroppings at all here. Most of the time we were in the alluvium of the Bautista Formation, or in recent sediments. As a result, we found only a few of the rock dwellers.
It was also interesting being at the junction of four drainages: the headwaters of the San Jacinto River, Palm Canyon, Santa Margarita River, and Coyote Creek. See map showing the drainages. There are two spots at Lookout Mountain where one can stand at the headwaters of three drainages.
Number of Unique Taxa On This Trail
This section not updated from the 11/22/08 fieldwork.
The following histogram gives the number of trails in our database that contain each taxon on this trail. We had 132 trails in our database when this histogram was made; 4 of those trails, including this one, are in this area of San Jacinto Mountain. A number of "1" means the taxon has only been found on this trail among the trails in our database; numbers of "4" or smaller may indicate taxa found only in this area of San Jacinto Mountain.

Fieldwork Dates and Summary of List Changes With Time The following table gives the dates the trail was walked and taxa recorded. After each visit, the table gives the total number of taxa on the list and the breakdown of the taxa without positive identification.

Comments On Specific Species Pinus quadrifolia. We were surprised to come across very few Pinus quadrifolia, or in fact any trees at all, in the first 2 miles of this trail. The needle count on the four specimens we did encounter was as follows:
# needles Plant # 1 2 3 4 1-4 3 1 2 6 2 11 4 2 2 3 1 8 5 1 2 - 5 8 See Needle Count on PCT North of SR74 and Pinus monophylla X P. quadrifolia: Addendum: Pinus juarezensis x P. monophylla for more information.
Quercus cornelius-mulleri. Plants at mile 2.5 are fairly clear Quercus cornelius-mulleri, but the plants at the beginning of the trail are ambiguous between Q. acutidens and Q. cornelius-mulleri. Since it is far from clear that there are two separate species here, we are just calling them all Q. cornelius-mulleri.
We thank Brendon Crill for help with the 22 November 2008 fieldwork, and Bill Sullivan for help with the 14 May 2009 fieldwork.
