This is a guide to the short 0.64 mile trail leading from the trail junction close to Round Valley Meadow to the campsites in Tamarack Valley. The trail is nearly flat, having less than 100 feet elevation gain and loss.

The easiest way to get to this trail is to take the Palm Springs Aerial Tramway to its top at Long Valley, and then the Round Valley Trail to this trail junction at mile 1.84 in that guide.

A free wilderness permit is required, available at the Ranger Station.

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 (not including the taxa seen only off-trail given at the end of the guide). We had 115 trails in our database when this histogram was made; 15 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 "15" or smaller may indicate taxa found only in this area of San Jacinto Mountain.

We found 5 additional species not in the above table, since they have not been fully identified yet. The unidentified ones are marked with ? or sp in the id? column in the guide, and have no entries 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.

Mile: 0.00 includes all mileages from 0.000 to 0.009; etc.

S: Side of trail on which the first occurrence is found: left, right, both, or center

#: On-Trail species are numbered in order of first occurrence on trail (touchable without leaving the trail). Off-trail species are in parentheses.

id?: Species without an entry in this column are positively identified. "?" means we are just guessing the identification; "sp" means the genera is probably known, but the species name is uncertain; "~" means we have 95% confidence that this is the determination, but have not yet positively identified it; "ssp" means the subspecies or variety needs to be determined.

#here gives the minimum number of on-trail plants of this species on this trail, with the number of locations on this trail following the /, using maximum values of 99/9. 1/1 means a single plant in a single location; 10/9 means 10 plants occurring in at least 9 locations, etc.

#all gives the number of plant trail guides, from all over southern California, that contain this taxon.
