Last known location: Jackson, WY

This wooden block features a stratified sequence of beech, green poplar, mahogany veneer, maple and Brazilian cherry that is cut by a series of thrust faults and involved in a number of thrust-related folds. Thrust faults ramp up section from a basal detachment atop the poplar. Thrust sheets of maple, Brazilian cherry, and mahogany veneer are involved in fault-bend folds over ramp-flat transitions. A stream cutting a trellis drainage patter of V-shaped river valleys is slowly eroding the fold thrust belt into a series of low foothills. This massive block measures roughly 12 by 5 inches, weighs nearly 3 lbs, and is finished with durable lacquer that highlights the natural colors and grains in the wood.
