Pusch Ridge Wilderness Area, Nature reserve in Pima County, United States.

Pusch Ridge Wilderness Area is a protected nature reserve within the Coronado National Forest that spans mountainous terrain with varied ecosystems. The land rises from desert lowlands to higher elevations, creating distinct zones with different plants and wildlife.

Congress protected this area in 1978 as part of legislation aimed at conserving endangered wilderness regions across the country. The designation was created to safeguard native wildlife populations including bighorn sheep from human development.

The name Pusch Ridge honours the Pusch family, early settlers in the Tucson area. The ridge is one of the last Arizona strongholds of desert bighorn sheep: 31 adults were released here in November 2013, and two lambs born in early 2014 were the first Catalina-born bighorns in nearly 25 years, spotted by an Arizona Game and Fish Department official.

The area is open to hiking with multiple trails offering different levels of difficulty for various skill levels. Overnight visitors need to obtain permits before entering the wilderness.

The south face of the Santa Catalina Mountains is made of Wilderness granite, whose bands of white, resistant rock form the steep cliffs above the desert. The dome-shaped core of Catalina granite sits in the middle of the range. The rock is granite, not quartzite.
