The basement geometry of the central Rocky Mountains provides a critical test for Laramide tectonic models. On a large scale, Laramide structural highs are better described as anastomosing, connected arches than as individual "uplifts." Thrust and reverse faults on the margins of Laramide arches dip both under and away from the ranges. Structural modeling shows that faults dipping toward the basins are commonly backthrusts off master thrusts which underlie and bring up the arches. These master thrusts alternate between emergent thrusts with major basement overhangs and blind thrusts below imbricate back thrusts.
