Arizona's geology is complex and its landscape varied. Yet, with Hiking Arizona's Geology as a companion, curious hikers with little or no background in geology can learn about Arizona's geologic features while enjoying some of the state's most scenic hiking trails. Fifty-five hikes organized by Arizona's three major geologic provinces are detailed, accompanied by information on the landscape encountered on each trail.
Originally shot in the IMAX format, this film includes footage from the rescue helicopters that combed the area looking for survivors after the initial eruption. These amazing scenes reveal an unearthly landscape of mud, ash, and steaming craters, which sharply contrasts with the pre-eruption scenery of pristine snow-covered peaks and the crystal waters of Spirit Lake.
As the film revisits the area a decade later, it is startling to see the rapid recovery after so much devastation. In this celebration of nature, "The Eruption of Mount St. Helens!" explores the power of nature to destroy, and to heal, in a cycle of destruction and creation that constantly changes the world in which we live.
