Yes it is safe to viewing grizzly bears from boats. We travel up Knight Inlet from Grizzly Bear Lodge to the Glendale River and transfer to a sixteen foot flat bottom skiff to make the bear watching easier, however the boat is still faster than a swimming grizzly. This July grizzly is cooling off and enjoying a swim along the shore. From the amount of its body above the water line it has already put on a good deal of fat just eating the sedge grass along the shore as well as Turing over rocks at low tide. The abundance of berries at this time of the year are also a help ad they wait for the salmon to return to the river.
Reporting a pectoral fin as an orca dorsal fin will lead to several days of radio talk about ones eye sight and value as a guide. The best policy is to make sure one see the “complete mammal” before reporting.
