Introduction

This guide begins at the Highway 67 trailhead, immediately south of Poway Road (not the Ellie Lane Trailhead to the north). Using this route, this hike is 6.2 miles roundtrip with ~1100 feet of elevation gain and loss. See Schad, 1998, pp. 79-81 for a map and description of this trail.
This guide was made from a single field trip, and has not yet been field-verified. Most mileages have not yet been added, but there are enough mileages and landmarks so that most people should be able to follow the guide.
See also Plants of Iron Mountain. This guide has an additional 27 species not found in that flora.

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 102 trails in my database when this histogram was made; 3 of those trails, including this one, are at the Blue Sky Ecological Reserve, Lake Poway and Iron Mountain Area. A number of "1" means the taxon has only been found on this trail among the trails in my database; numbers of "3" or smaller may indicate taxa found only in this area.
