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 106 trails in our database when this histogram was made; 9 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 "9" or smaller may indicate taxa found only in this area of San Jacinto Mountain.

The Plant Guide

The plant names have been updated to the Second Edition Jepson Manual system.

Version for printing, without lines and other text on this page: html (4 pages) or pdf Clickbook booklet (1 double-sided page). (See printing instructions for an explanation of these options)

The mileages in the guide come from Topo!. The total mileage is almost surely slightly underestimated, probably by no more than 10%, due to the tight switchbacks on the trail that are not accurately measured by that program. The elevations come from the topo map, and should be fairly precise.
