The name Tuolumne is of Native American origin and has been given different meanings, such as Many Stone Houses, The Land of Mountain Lions and, Straight Up Steep, the latter an interpretation of William Fuller, a native Chief. Mariano Vallejo, in his report to the first California State Legislature, said that the word is "a corruption of the Indian word talmalamne which signifies 'cluster of stone wigwams.'" The name may mean "people who dwell in stone houses," i.e., in caves.
