A Rissos dolphin leaps from the ocean in a full breach. Note distinguishing and highly variable skin and dorsal fin patterns, characteristic of this species. White scarring, likely caused by other Risso dolphins teeth, accumulates during the dolphins life so that adult Rissos dolphins are almost entirely white. Offshore near San Diego.
Species: Risso's dolphin, Grampus griseus

Large male elk (bull) in snow covered meadow near Madison River. Only male elk have antlers, which start growing in the spring and are shed each winter. The largest antlers may be 4 feet long and weigh up to 40 pounds. Antlers are made of bone which can grow up to one inch per day. While growing, the antlers are covered with and protected by a soft layer of highly vascularised skin known as velvet. The velvet is shed in the summer when the antlers have fully developed. Bull elk may have six or more tines on each antler, however the number of tines has little to do with the age or maturity of a particular animal.
Species: Elk, Cervus canadensis

Roosevelt elk, adult bull male with large antlers. This bull elk has recently shed the velvet that covers its antlers. While an antler is growing, it is covered with highly vascular skin called velvet, which supplies oxygen and nutrients to the growing bone; once the antler has achieved its full size, the velvet is lost and the antler's bone dies. This dead bone structure is the mature antler, which is itself shed after each mating season. Roosevelt elk grow to 10' and 1300 lb, eating grasses, sedges and various berries, inhabiting the coastal rainforests of the Pacific Northwest.

Hiker in Buckskin Gulch. A hiker considers the towering walls and narrow passageway of Buckskin Gulch, a dramatic slot canyon forged by centuries of erosion through sandstone. Buckskin Gulch is the worlds longest accessible slot canyon, running from the Paria River toward the Colorado River. Flash flooding is a serious danger in the narrows where there is no escape.

Buckskin Gulch hiker. 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 sixteen individual photos.
