4th IUSS Soil Classification Conference Field Tour Guidebook The surface of the closed Sarpy County Landfill (Stop 3) is well vegetated with Indiangrass, goldenrod smooth brome and tall grass prairie species. The convex shape prevents ponding and enhanced infiltration by precipitation. This view is from Landfill Site 2 northeastward toward Landfill Site 1. 125
