The Mogollon Rim is a topographical and geological feature cutting across the northern half of the US state of Arizona, about 118 miles (190 km) southeast of Sedona, Arizona. Please note that while there are no designated stargazing areas, the rim sits just west of the International Dark Sky Community Cottonwood, Arizona, and provides ample opportunity for hiking, fishing, biking, camping, and more. One EarthSky reader calls this area “a true geological wonder hosting sedimentary, volcanic and metamorphic rock dating back to the Precambrian era … More elk than people. Some of the darkest, most translucent skies in North America. Also home to the Discovery Channel Telescope!” For more information, please visit online or call the Coconino National Forest at 928-477-2255, Monday through Friday between 7:30 a.m. – 4:00 p.m. Pacific Time.
