Local relief in thisregion in most places is on the order of 300feet (91 m). Hillslopes are steep, and there aremany cliffs and outcrops of sandstone andlimestone. Upland tracts are rather broad, andcommonly are upheld by sandstone rirnrock.Valleys are narrow, but are rather deeplyfilled, nevertheless, by Pleistocene and Holocenealluvium, outwash, and lake deposits.The northern part of the Crawford Uplandhas been glaciated, but here the Bllinoianglacial boundary, which is about one mileahead, nearly coincides with the boundarybetween the physiographic divisions.Ma nsfield Formation sandstone from thequarry to the left (north) was used as a glasssand.Cross the approximate location of the thalwegof a valley in the pre-Pennsylvanian erosionalsurface.Upper Mansfield Formation sandstone, shale,underclay, and weathered coal are exposed inthe roadcut on the left (north).
