A thick sequence (∼177 m) of aggradational deposits was studied in the lower Hope Valley. Valley fill is preserved in a tectonic depression, which is associated with a releasing bend on the active strike slip Hope Fault. Our results indicate that local basin subsidence since the last glacial maximum (LGM) occurred at a rate of 1.4–2.5 mm/yr, which roughly matches the regional tectonic uplift rate. The approximate balance between uplift and basin subsidence resulted in a local late Pleistocene sedimentary pattern that was primarily controlled by climate-induced processes of aggradation and degradation.

Here we describe deposits and subsurface sedimentary structures...
