Gently sloping uplands comprise most of the study area. Progresso and Pinon soils are found on these <br />areas. Pinon is less than 20 inches to bedrock, whereas Progresso is 20 to 40 inches. Progresso soils <br />developed in residuum from interbedded sandstone and shale and have well developed Bt argillic horizons <br />and underfying Bkcalcic horizons. The Banc soil is found as an inclusion with Progresso and Pinon. Pinon <br />soils are developing in thin residuum from sandstone in areas where sandstone ledge rock is near or at <br />the surface. Weathered shale bedrock is often found beneath the relatively thin sandstone ledge rock. <br />Pinon soils have a zone of secondary calcium carbonate accumulation. <br />The Barx soil is deep (40 to 60 inches to either sandstone or shale bedrock) to very deep (greater than 60 <br />inches to either sandstone or shale bedrock) and has a well developed Bt argillic and Bk calcic horizon. <br />It has loam, sandy clay loam, or clay loam textures in the Bt particle size control section, and is developing <br />in wind deposited loess over residuum from sandstone and shale at depth in the soil profile. The Barx soil <br />is found on the gently sloping mesa-like surface in the southeast corner of the study area. <br />Soils and Geomorphology -1996 <br />The study area included the Garvey and Burbridge properties located within the original 1988 survey. <br />This survey updated map unit delineations and provided detailed topsoil salvage depths for the above <br />properties. <br />Soils and Geomorphology -1998 <br />The study area included the Morgan property located within the original 1988 survey and additional <br />areas north of BB Road that were not surveyed in 1998. This survey updated map unit delineations <br />and provided detailed topsoil salvage depths on the Morgan property as well as detailed baseline soil <br />information on properties located north of BB Road. The geology and geomorphology are similar to <br />that located in the original 1988 survey. <br />(REVISED2/00) 2.04.9-4 <br />
