The sample site is on the southernmost of the two rivulets, 250 feet upstream from Chalone Creek, and approximately 100 feet upstream from the North Wilderness Trail. The sample site is adjacent to a wild pig trap (chain link enclosure) about 0.1 miles downstream from the location of Willow Spring (as shown on the USGS 7.5 minute topographic quadrangle map, Bickmore Canyon, CA). This spring once served as a water supply for the old campground that was located at the present monument maintenance headquarters but is no longer used.
