Grizzly bears have long nonretractile claws which are 5 to 10 cm (2 to 4 inches) but they are not good climbers. Their claws are used for digging, picking fruits, and catching prey. In this case the prey would be the many pink salmon in the entrance to the spawning channel overlooked by the lodge’s viewing platform.
This photo was taken from the viewing stand on Knight Inlet’s Glendale River. Grizzly Bear Lodge is permitted to use the stands after August 24th. By this time the salmon have been in the river for close to two weeks and the bears have come to the area to fatten for the winter, because of the abundance of pink salmon. Grizzly bear mothers and cubs are common in the viewing area and this photo has yearling triplets below the stands keeping close attention on another bear fishing in the other end of the pool (30 meters away). This area of the pool is to deep for the cubs to try fishing so mother catches and brings the salmon to them on shore; but she also keeps an eye on other grizzly bears fishing in the area.
