Introduction

The mileages given here are uncorrected readings from my pedometer on 9/25/03, which is a bit lower than the mileage posted on the few trail signs. (The difference is well within my pedometer error of ~6%.) Later versions will attempt to rectify the difference. Topo! mileages using the trail on the USGS topographic maps are lower than my pedometer, and are likely to be underestimated by as much as 30% here due to the large number of tight switchbacks on this trail.

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.

Comments On Specific Species

Ceanothus cordulatus and Amelanchier utahensis. The first occurrences of these taxa were dead in 2003. The first live Ceanothus cordulatus specimen in 2003 is noted, without a number. There are no other specimens of Amelanchier utahensis on the trail.

Epilobium canum. These plants, like many of the ones we see at high elevations of the San Gabriel Mountains, seem to be hybrids between the two subspecies. See Comments on the Jepson Manual and A Flora of Southern California by Munz: Epilobium canum.

Prunus virginiana var. demissa?. This shrub was resprouting, with many strong stems, in 2003. It is likely that these are the same plants found in great abundance along the Manzanita Trail just below this point.

~Allium monticola. Only dead inflorescences were observed in 2003, but the bract length, bract shape, tepal length, and pedicel lengths are only consistent with this id. However, we still qualify this id as only being 95% since we have not observed a bloom yet.
The second occurrence of dead onion inflorescences was at 0.07 miles from the top. Although we did not measure those dead inflorescences, only Allium monticola is found above 9000 feet, according to the floras, and hence again this is the likely id.
