Huachuca Mountains

The Huachuca Mountains are a gem of biological diversity. These sierra sit just north of the Sonora border with their very southern slope descending across the border into Mexico. The southwest portion are relatively remote, accessible by dirt road only. A small paved road from the north terminates at the popular Parker Canyon Lake. West of the Huachucas lie the San Rafael Valley and Canelo Hills. The north part of the range hosts Fort Huachuca, a large military reservation. The south end has a small Park Service property called Coronado National Memorial. Several birding hotspots are popular, especially Ramsey Canyon preserve on the east side above Sierra Vista. This range is known for it's diversity of plants, birds, and herps.

Some areas near the highest points and north-facing slopes host mixed conifer. Much of the range and foothills are dominated by robust oak woodland. The range has a strong affinity to Madrean woodlands of central and eastern Sonora.

This range has hosted an ocelot for many years, known since 2011, but possibly longer and undetected prior. It already appeared to be a relativelt older individual at that point and is believed to be the oldest documented US ocelot. It has been detected as recently as mid-2023.

The Huachuca Mountains high point is 9466 feet (2885 meters) and is named Miller Peak.
