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:

The trail itself traverses a number of distinct terrains, each with its own suite of plant species:

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.

We found 16 additional species not in the above table, since they have not been identified yet. The unidentified ones are marked with ? or sp in the id? column in the guide, and have no entry in the #all column.

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. See Explanation of Plant Trail Guides to understand the symbols below.

The fieldwork on 11/11/2008 was to mile 1.99, and on 11/22/08 to mile 4.13.

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:

# needlesPlant #
1234 1-4
31262  11
42231  8
512-5  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.
