Summary

Description
English: Animas Valley above Animas City — Colorado.
  • There is topographic unconformity between the maturely eroded upland and the youthful gulches cutting the lower slope. The steepness of that slope and the truncation of interstream spurs are largely due to glacial abrasion.
  • The apparent old age of the stream is due to its meandering on an alluvial flat. This flat is underlain by silt deposited above the dam formed by the Wisconsin terminal moraine. As the outlet through the dam was deepened, many oxbows were cut off. Similar conditions are found in several other valleys.
