Abstract Using 10 Be and 26 Al measured in sediment and bedrock, we quantify rates of upland erosion and sediment supply to a small basin in northwestern New Mexico. This and many other similar basins in the southwestern United States have been affected by cycles of arroyo incision and backfilling several times in the past few millennia. The sediment generation (275 ± 65 g m −2 yr −1 ) and bedrock equivalent lowering rates (102 ± 24 m myr −1 ) we determine are sufficient to support at least… CONTINUE READING
