Genetically, North American grizzlies are closely related; in size and coloring, the California grizzly was much like the grizzly of the southern coast of Alaska. In California, it was particularly admired for its beauty, size, and strength. The grizzly became a symbol of the Bear Flag Republic, a moniker that was attached to the short-lived attempt by a group of American settlers to break
