To improve knowledge of the Teton fault’s ground-rupturing earthquake history, we excavated trenches across two fault scarps near the southwest shore of Leigh Lake. Detailed stratigraphic and sedimentologic analyses allow preliminary inferences regarding the fault history. The trenches exposed faulted glacial sediments and overlying hillslope colluvium sediments, documenting at least two fault ruptures since deglaciation of the range front at ~15 ka.
