Some days the grizzly bear watching on July and early August are quite warm it is unlikely this was a “bath” rather think back on a hot day that you may have experienced and add a heavy fur coat. That is the likely reason mother and cub are in the water. They are in the Glendale River estuary which is a mixture of fresh and salt water so their coast will not contain allot of salt when dry. The sedge grass along the shore is the main reason for the grizzly bears to be in the area as the salmon to not appear until late August.
