Maps and photographs made by Willard D. Johnson in 1907 and published by W. H. Hobbs in 1910, together with unpublished illustrations and an incomplete manuscript by Johnson, show convincingly that the faulting that took place near the town of Lone Pine at the time of the Owens Valley earthquake of 1872 involved both dip-slip and right-lateral components of movement. The pattern of movement at Lone Pine in 1872 is opposed to the postulate of regionally systematic left-lateral movement along the east side of the Sierra Nevada during the Cenozoic, but does not prove systematic regional right-lateral movement. Detailed geologic mapping is needed to fully describe the regional pattern of movement during the Cenozoic.
