Biogeomorphic processes and archaeological site formation in Absaroka Mountains of northwestern Wyoming
… prehistoric flaked stone scatter in the Absaroka Mountains of northwestern Wyoming. Pocket gopher activity was documented at the site in a 1-hectare sample area surrounding a small sag pond. It was suspected the sediment pocket gophers transport to the surface while digging subsurface …

Rock Glacier Distribution, Activity and Movement, Northern Absaroka and Beartooth Ranges, MT, USA
<p>Rock glaciers of the northern Absaroka and Beartooth Ranges have not previously been described. Six-hundred and sixty rock glaciers were hand digitized in a GIS and evaluated using 11 distributional characteristics. Beartooth rock glaciers were found to occur at higher elevations, receive more …

Establising a high-frequency standard reference sequence stratigraphy, sea-level curve, and biostratigraphy for Morrowan strata of the Lower Absaroka I time slice based upon the Bird Spring Formation, Arrow Canyon, Nevada
… reference for the Morrowan portion of the Lower Absaroka I supersequence. The stratigraphic architecture of Morrowan strata in Arrow Canyon was largely controlled by high-amplitude (100-m), high-frequency sea-level changes. Outcrop data and facies stacking patterns define 59 fifth-order …

The Provenance of Eocene Tuff Beds in the Fossil Butte Member of the Green River Formation of Wyoming: Relation to the Absaroka and Challis Volcanic Fields
… sources. Based on age and proximity, the Absaroka and Challis volcanic fields are the likely sources of tephra deposits in Fossil Basin and the Greater Green River Basin. Calc-alkaline tephras in these lacustrine basins have similar magmatic characteristics to the tuff of Ellis Creek (48.4 …

Mountains as Crossroads: Temporal and Spatial Patterns of High Elevation Activity in the Greater Yellowstone Ecosystem, USA
… on new fieldwork and lithic collections from the Absaroka and Beartooth Mountains in the Greater Yellowstone Ecosystem (GYE) of the Rocky Mountains, which was a vital crossroads of prehistoric cultures for more than 11,000 years. I include five interlocking analyses. First, I consider the impacts …

Tectonic implications of mantle source changes recorded by Eocene-Oligocene basalts from the Dillon volcanic field southwest Montana (USA)
… 51-40 Ma central Idaho Challis and the 54-44 Ma Absaroka volcanism. Multiple tectonic models have been proposed to explain the ~33-16 Ma middle and upper Dillon volcanism (e.g., Farallon slab rollback, slab tearing/foundering, lithospheric drip), which erupted during the later period of regional …
