However, spatially-variable rock strength Received in revised form 28 August 2018 can influence the topographic expression of such transient landscapes, especially in layered rocks, where Accepted 4 October 2018 strength variations can mask topographic signals expected due to changes in climate or tectonics. Here, Available online xxxx 2 we analyze the landscape response to base-level fall in Young Womans Creek, a 220 km catchment on Editor: J.-P.
