What is the influence of glacial processes in driving erosion and uplift\udacross the European Alps? It has largely been argued that repeated erosion\udand glaciation sustain isostatic uplift and topography in a decaying orogen.\udBut some parts of the Alps may still be actively uplifting via deep\udlithospheric processes. We add insight to this debate by isolating the role\udof post-glacial topographic forcing on erosion rates. To do this, we quantify\udthe topographic signature of past glaciation on millennial-scale erosion\udrates in previously glaciated and unglaciated catchments at the easternmost\udedge of the Austrian Alps. Newly measured catchment-wide erosion rates,\uddetermined from cosmogenic 10Be in river-borne quartz, correlate with\udbasin relief and mean slope. GIS-derived slope–elevation and slope–area\uddistributions across catchments provide clear topographic indicators of the\uddegree of glacial preconditioning, which further correlates with erosion\udrates. Erosion rates in the easternmost, non-glaciated basins range from 40\udto 150 mm ky−1 and likely reflect underlying tectonic forcings in this region,\udwhich have previously been attributed to recent (post 5 Ma) uplift. By\udcontrast, erosion rates in previously glaciated catchments range from 170 to\ud240 mm ky−1 and reflect the erosional response to local topographic\udpreconditioning by repeated glaciations. Together, these data suggest that\udHolocene erosion across the Eastern Alps is strongly shaped by the local\udtopography relict from previous glaciations. Broader, landscape-wide\udforcings, such as the widely debated deep mantle-driven or\udisostatically driven uplift, result in lesser controls on both topography and\uderosion rates in this region. Comparing our data to previously published\uderosion rates across the Alps, we show that post-glacial erosion rates vary\udacross more than 2 orders of magnitude. This high variation in post-glacial\uderosion may reflect combined effects of direct tectonic and modern climatic\udforcings but is strongly overprinted by past glacial climate and its\udtopographic legacy
