This dataset contains picks of the sub-Cretaceous unconformity, identified by the truncation of underlying geological units, in west-central Alberta.
The study area covers NTS map sheets 83G, 83J, 83K, and parts of 83F. The southwest limit of the study area is defined by the approximate limit of the main Cordilleran deformation.
