Ramsey Canyon is a stream-cut, vertical-sided gorge. Cold air drainage from the upper canyon results in a well-defined microclimatic habitat that supports Mexican flora and fauna and plants that normally occur only at higher elevations. The site is also frequented by more species of hummingbirds than any other area in the United States.
