Short summary

Mountain rivers play an important role in storing organic carbon (OC) on the landscape. We use field sampling to quantify OC concentrations in floodplain soils of two disparate mountain river basins. We find that local valley geometry and hydrology are dominant controls on OC concentration. This implies that OC concentration cannot be predicted using consistent downstream trends. Instead, geomorphology must be accounted for to understand the spatial distribution of OC in river basins.
