Introduction

The Alcoholic Pass Trail traverses Coyote Mountain in a cross-section from its south side to its north side, from Coyote Creek to Clark Valley. Coyote Mountain has a very odd profile here, with a steep southern slope, an almost flat top, and a long very gentle northern slope. In contrast, in the area of the peak of Coyote Mountain, the profile is nearly symmetric. The complex profiles are undoubtedly due to Coyote Mountain itself being an uplifted block between two strands of the San Jacinto Fault, and therefore subjected to considerable stress and strain. The topography here is also heavily influenced by the West Coyote Mountain Fault, which goes through the saddle here and separates the Ocotillo Formation on the west from the basement rocks on the east.
The trailhead is on the main Coyote Canyon dirt road, 2.5 miles north of the end of the pavement on DiGiorgio Road in Borrego Springs. Except after heavy rains, or when Coyote Creek has a lot of water, the dirt road is usually passable with careful driving by passenger cars. Wallace Tucker drove his Prius to the trailhead with no problems on 2/23/10, and we've seen mini-vans parked at the trailhead before.
The hike begins on the north edge of Coyote Creek Wash at a signed trailhead. At mile 0.16, you begin ascending a steep slope and gain 500 feet of elevation in the next 0.48 miles, a punishing rate of 1000 feet per mile that is made trivial if one is going at a slow botanizing pace. The trail then is essentially level for the next 0.27 miles. The trail then descends at the very gentle rate of 220 feet per mile for the 2.7 miles down to Rockhouse Canyon Road.
Highlights of This Trail

The following histogram gives the number of trails in our database that contain each taxon on this trail. We had 191 of our trails and floras in our database when this histogram was made; 53 of those trails and floras, including this one, are in Anza-Borrego State Park. A number of "1" means the taxon has only been found only on this list, among all the trails in our database.

We found 1 additional taxon not in the above table, since it has not been fully identified yet. The unidentified ones are marked with ?, sp or ssp in the id? column in the guide, and have no entries in the #all column.
The taxa that are unique to this trail, or found on only four or fewer other trails or floras that we have done (up to five total trails including this one), out of all 191 plant trail guides throughout southern California, as of 26 February 2010, are:

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.

Visit Date Visit # # taxa # "?" # "sp" # "~" # "ssp"
12/22/2007 1 40 2 5 10 0
12/27/2007 2 43 2 4 9 0
3/21/2008 3 89 1 3 5 0
2/23/2010 4 90 1 0 3 0

Note what a difference it makes covering the trail in December or in March! The number of reliably-identified taxa more than doubled.
The trail was only covered to mile 2.93 on 2/23/10; 2.55 on 12/22/07; and mile 1.41 on 3/21/08. Just the lower two miles were covered on 12/27/07.
We thank RT Hawke and Wallace Tucker for assistance with the 2/23/10 fieldwork.

This is a working list, about which we make no guarantees at all until we officially release it. Use at your own risk!

The mileages have been obtained by a GPS recording for most of the species, with the route then drawn using Topo!. The relative mileages are probably accurate to ~0.02 miles, with the absolute accuracy somewhat worse.

Comments On Specific Species

Krameria erecta. There were no fruit or flowers on the first plants on the trail, so their determination is not 100% positive; the identification comes from a plant at mile 0.37 that had fruit.
Ferocactus cylindraceus. The varieties are not recognized in the Flora of North America treatment for the excellent reason that they don't actually exist.
