Fanciful White Pocket is nature's artwork. In a remote section of northern Arizona, this otherworldly expanse of twisting, contorted rock masses evokes colossal, multicolored baked goods fallen from the sky. Some geologists believe the unusual formations may result from once-liquefied earthquake residue. Hikers can walk the fantasy landscape along a well-marked, 4-mile trail. Millions of years old, the rock chunks sit amid eroded escarpments, tiny streams, cliffs and sandy areas. Bird sightings -- eagles, hawks, raptors, falcons -- are common.
