The connection between climate and erosion is fundamental to understanding the evolution of Earth's surface, yet identifying mechanisms of climate-modulated erosion is limited by a lack of upland records of landscape change. Sediment storage time in uplands is often shorter than glacial-interglacial cycles, but landscape form integrates over timescales that include multiple climate cycles (Perron, 2017). Direct records of slope behavior are rarely preserved (Pederson et al., 2000), so reconstructions of climate-modulated hillslope processes rely on indirect evidence of changes to sediment and/or water flux preserved in river terraces, floodplains, and lake/ marine deposits, which can be obscured by the effects of sediment transport and preservation bias (Willenbring & Jerolmack, 2015).Landscapes at middle latitudes experienced wide temperature ranges before and after glacial maxima, and thus present an opportunity to study landscape response to intermittent cold (but non-glacial) periods throughout the Quaternary. Cold conditions can promote rock fracturing (Hales & Roering, 2007;Hallet et al., 1991). On hillslopes, seasonal and/or abrupt thaw of permafrost can accelerate soil flux via solifluction and slope failures
