FIELD TRIP TO THE WEST FORK OF BEAR CANYON
The West Fork of Bear Creek is a nearly pristine
riparian area near Mount
Baldy Village. There is a second Bear
Canyon in the Angeles
National Forest which is located near San Gabriel Canyon.
The trails in the Bear Canyon near San Gabriel Canyon
have been closed for public safety. To
reach the Baldy Bear
Canyon one goes along the Baldy Trail,
the original miners’ trail to the summit of Mount San Antonio,
until Bear Flat, a small meadow. From
Bear Flat we shall follow an unmaintained trail that leads to our study
site. This trail originally led to a
USFS lookout on Lookout
Mountain where Nobel
Laureate Albert Michelson made his best measurements of the speed of
light. The trail does not appear on
current USGS topographical maps and has been mapped by the instructor. His field notes provide the basis for the map which we shall use. He remapped the area in June, 2008 with a
Garmin GPS and mapped the route in UTM coordinates and
a profile of the route. Using ArcView,
the premier GIS software, he has generated two additional maps. Each map has 4 layers: the trail located by
GPS (red, from the village to Bear Flat; magenta, from Bear Flat upward [We won’t
take this.]; orange, from Bear Flat to the west fork), the hydrology, the 7.5’ topographical map or a satellite
image, and the earthquake faults in the area (shown as solid black lines).
The field trip is scheduled for
Saturday, 20 September and will last most of the day. Lunches will be provided. You should wear comfortable hiking boots and
bring a day pack with the 10 essentials.
You also want to bring writing materials and a camera.
