A hiker considers a log suspended high overhead in the Buckskin Gulch Narrows, left there by a previous flash flood. A hiker moves through the deep narrow passages of Buckskin Gulch, a slot canyon cut deep into sandstone by years of river-induced erosion. In some places the Buckskin Gulch narrows are only about 15 feet wide but several hundred feet high, blocking sunlight. Flash floods are dangerous as there is no escape once into the Buckskin Gulch slot canyons. This is a panorama made of twelve individual photos.
