One prospector in Southern California, William F. Holcomb (nicknamed ``Grizzly Bill'' Holcomb), was particularly well-known for hunting grizzly bears in what is now San Bernardino County. The last hunted California grizzly was shot in Tulare County, California, in August 1922, although no body, skeleton or pelt was ever produced. Two years later in 1924, what was thought to be a grizzly was spotted in Sequoia National Park for the last time, and thereafter, grizzlies were never seen again in California.

A centripetal force directed towards the center of the turn is required for any object to move in a circular path. In the context of a rotating space station it is the normal force provided by spacecraft's hull that acts as centripetal force. Thus, the ``gravity'' force felt by an object the centrifugal force perceived in the rotating frame of reference as pointing ``downwards'' towards the hull. In accordance with Newton's Third Law the value of little g (the perceived ``downward'' acceleration) is equal in magnitude and opposite in direction to the centripetal acceleration.
