They Might Be GIANTS - Nevada Indian legend of 12 foot red-haired giants that lived in the area when they arrived. The story has the Native American's killing off the giants at a cave. Excavations of guano in 1911 turned up this human jaw. Here it is compared to a casting of a normal man's jawbone. In 1931 two skeletons were found in a lake bed. One was 8' tall, the other just under 10' tall.
