This privately published Web site functions as a detailed natural history guide to California's San Gabriel Mountains. Users can access a wealth of detailed information regarding the region's plants, animals, weather conditions, etc. The road guides are so detailed that the reader may almost feel as if he or she is actually there. While the text is dense and images are few and far between, almost every page of this Web site contains numerous links to other sites that offer useful photos. The incredible detail of this Web site may be off-putting for those seeking a casual glimpse at the San Gabriel Mountains, but for those more actively interested in the region, this site would be a rich natural history resource filled with careful observations and well-referenced information.
