Introduction

The Fobes Trail travels from the northern part of Garner Valley to the Pacific Crest Trail at the Desert Divide. The trailhead is reached by turning north of SR74 onto a 4 mile dirt road, Fobes Ranch Road (6S05). Fobes Ranch Road is not signed like the other roads along SR74; it has only a sign on the fence by the gate, which is hard to see from SR74.

The turnoff from SR74 is 6.8 miles southeast of Mountain Center just beyond mile marker 66. On Fobes Ranch Road, stay left at a fork 0.4 miles north of SR74, and stay right at the signed fork at mile 3.6. The signed Fobes Trailhead only has parking for ~3 vehicles, with additional parking a bit farther up the road.

See Hike 80 in Robinson and Harris, San Bernardino Mountain Trails, sixth edition, January 2006, p. 204; and Hike 48 in Ferranti and Koenig, 100 Great Hikes in and near Palm Springs, 2000, p. 103.

This guide is mainly the result of two trips in March and April 2007 only to mile 1.12, along with a trip in July 2009 that extended the guide to the top of the trail without much botanizing on the lower part of the trail.

Number of Unique Taxa On This Trail

The following histogram gives the number of trails in our database that contain each taxon on this trail. We had 101 trails in our database when this histogram was made; 7 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 "7" 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. See Explanation of Plant Trail Guides to understand the symbols below.

The fieldwork on 3/18/07 and 4/4/07 was only to mile 1.12. The fieldwork on 7/2/09 concentrated primarily on mile 1.12 to the top of the trail.

We thank an anonymous person for help with the fieldwork on 3/18/07, and another anonymous person for help on 7/2/09, and Mike Crouse for help with the fieldwork on 7/2/09.
