The stratigraphy of the Wasden site exceed six meters in depth, and are made up of finely stratified, hortizontally bedded loessial sediments (Butler 1968b:7). The strata held abundant microfauna, bird, and large faunal remains. Deposition consisted of fine laminae of wind blown and water deposited sediments broken up by periodic episodes of rock-fall caused by frost weathering of the laminar basalts constituting the walls and overhang.
