Bighorns Mountains of Wyoming: Formation of Basement-involved Foreland Arches

Bighorns Mountains of Wyoming: Formation of Basement-involved Foreland Arches

This three year (2009-12) collaborative project will integrate arch-scale upper crustal geometries from surface exposures and petroleum industry subsurface data with the results of a hybrid seismic experiment. The passive component of this experiment consists of a 1.25 year (2009-10) deployment of 27 broadband seismometers that densify the EarthScope transportable array, a 6.5 month deployment of 220 short period seismometers, and a 9 day deployment of 800 high frequency "Texan" seismometers.
