	abstract = {The 72-km-long Teton normal fault bounds the eastern base of the Teton Range in northwestern Wyoming, USA. Although geomorphic surfaces along the fault record latest Pleistocene to Holocene fault movement, the postglacial earthquake history of the fault has remained enigmatic. We excavated a paleoseismic trench at the Buffalo Bowl site along the southernmost part of the fault to determine its Holocene rupture history and slip rate. At the site, \~{}6.3 m of displacement postdates an early Holocene (ca. 10.5 ka) alluvial-fan surface. We document evidence of three surface-faulting earthquakes based on packages of scarp-derived colluvium that postdate the alluvial-fan units. Bayesian modeling of radiocarbon and luminescence ages yields earthquake times of ca. 9.9 ka, ca. 7.1 ka, and ca. 4.6 ka, forming the longest, most complete paleoseismic record of the Teton fault. We integrate these data with a displaced deglacial surface 4 km NE at Granite Canyon to calculate a postglacial to mid-Holocene (14.4{\textendash}4.6 ka) slip rate of \~{}1.1 mm/yr. Our analysis also suggests that the postglacial to early Holocene (14.4{\textendash}9.9 ka) slip rate exceeds the Holocene (9.9{\textendash}4.6 ka) rate by a factor of \~{}2 (maximum of 3); however, a uniform rate for the fault is possible considering the 95\% slip-rate errors. The \~{}5 k.y. elapsed time since the last rupture of the southernmost Teton fault implies a current slip deficit of \~{}4{\textendash}5 m, which is possibly explained by spatially/temporally incomplete paleoseismic data, irregular earthquake recurrence, and/or variable per-event displacement. Our study emphasizes the importance of minimizing slip-rate uncertainties by integrating paleoseismic and geomorphic data sets and capturing multiple earthquake cycles.},

	abstract = {Prominent scarps on Pinedale glacial surfaces along the eastern base of the Teton Range confirm latest Pleistocene to Holocene surface-faulting earthquakes on the Teton fault, but the timing of these events is only broadly constrained by a single previous paleoseismic study. We excavated two trenches at the Leigh Lake site near the center of the Teton fault to address open questions about earthquake timing and rupture length. Structural and stratigraphic evidence indicates two surface-faulting earthquakes at the site that postdate deglacial sediments dated by radiocarbon and optically stimulated luminescence to \~{}10{\textendash}11  ka⁠. Earthquake LL2 occurred at \~{}10.0  ka (9.7{\textendash}10.4 ka; 95\% confidence range) and LL1 at \~{}5.9  ka (4.8{\textendash}7.1 ka; 95\%). LL2 predates an earthquake at \~{}8  ka identified in the previous paleoseismic investigation at Granite Canyon. LL1 corresponds to the most recent Granite Canyon earthquake at \~{}4.7{\textendash}7.9  ka (95\% confidence range). Our results are consistent with the previously documented long-elapsed time since the most recent Teton fault rupture and expand the fault{\textquoteright}s earthquake history into the early Holocen},
