This dataset documents the measurements accompanying the figures in Parker & Pearson, 2021 (Pre-thrusting stratigraphic control on the transition from a thin- to thick-skinned structural style: an example from the double-decker Idaho-Montana fold-thrust belt).

Field measurements using Brunton compass (hinge inclinometer). Locations recorded in decimal degrees using a Garmin eTrex (WGS projection).
