DAWSON SADDLE TRAIL TO THROOP PEAK, SAN GABRIEL MTS
JUNE 2009 PAGE ONE
Photographs by Michael Charters




Due to the willingness of my wife and daughter to look after our new puppies today, I was able to take a hike on a trail I had been waiting five years to do. The trailhead at Dawson Saddle, highest point on the Angeles Crest Highway, has been inaccessible ever since the closure of the highway between Islip Saddle and Vincent Gap. There were some very nice things growing along the trail, including to my surprise a new species for me, Peirson's lupine, an uncommon San Gabriel endemic, which as the above picture shows was there in some profusion. The view from the top of Throop Peak has got to be one of the best in the San Gabriels, and even on a warm June day it was a pleasant hike. It is 2-1/2 miles from the trailhead to the peak. A Tom Chester plant guide for this trail is here. The pictures on the first page were taken in several springy areas and at a couple of other stops along the highway a few miles from Dawson Saddle. An upside-down V next to the common name indicates a species that was new to me when I photographed it on this field trip, and an asterisk denotes a non-native taxon.
