Ozark Glade

Caption

A glade on Stegall Nountain looking toward Thorny Mountain in the Ozarks. The rock is rhyolite, ancient volcanic rock dating from the Precambrian period that was uncovered by millions of years of erosion. Hot, dry and covered only thinly with soil, the Ozark glades create their own desert-like microclimates and are home not just to collared lizards but also to scorpions, tarantulas and prickly pear cactus.
