Documenting mine spoil genesis has been limited in the Western States. Few areas have {open_quotes}before{close_quotes} and {open_quotes}after{close_quotes} type data and for some mines older reclamation areas are limited. Soil samples were collected from 8-11 year old reclaimed spoil as part of a rooting depth study completed in June 1987 at the Navajo Mine. Samples were collected in 25 cm increments to depths of at least 200 cm and most often to 350 cm at a total of fifteen different reclamation plots. The spoil was composed of various amounts of shale and sandstone. The sites represented different topographic positions (swale/backslope), reclamation ages (8 to 11 years), slopes (0-15%), and topdressing treatments (with and without).
