Results of 2-D flexural modeling of the N Bighorn and N Green River basins in the Wyoming foreland province suggest that these basins formed as flexures in response to loading by basin-margin uplifts and basin sedimentary sequences. The N Bighorn Basin subsided due to loading by the Beartooth uplift along its W margin. The N Green River Basin developed as a result of concurrent loading by the Wyoming thrust belt to the W and the Wind River uplift to the E. Tectonic loading from basement-involved uplifts played a major role in subsidence and sedimentation, as evidenced by isopach patterns within each basin. Lithospheric flexural rigidities of 10 21 -10 22 newton metres (N.m) can adequately explain subsidence in both basins.-Authors
