"MT643"|8|"BLO"|"Blowout"|A saucer, cup, or trough-shaped depression formed by wind erosion on a pre-existing dune or other sand deposit, especially in an area of shifting sand or loose soil or where protective vegetation is disturbed or destroyed. The adjoining accumulation of sand derived from the depression, where recognizable, is commonly included. Blowouts are commonly small.  Typically__to__acres.|"297625"
"MT643"|8|"CLA"|"Clay spot"|A spot where the surface texture is silty clay or clay in areas where the surface layer of the soils in the surrounding map unit is sandyloam, loam, silt loam, or coarser.  Typically__to__acres.|"297626"
"MT643"|8|"ESB"|"Escarpment, bedrock"|A relatively continuous and steep slope or cliff, produced by erosion or faulting, that breaks the general continuity of more gently sloping land surfaces. Exposed material is hard or soft bedrock.|"297627"
"MT643"|8|"GPI"|"Gravel pit"|An open excavation from which soil and underlying material have been removed and used, without crushing, as a source of sand or gravel.  Typically__to__acres.|"297628"
"MT643"|8|"GRA"|"Gravelly spot"|A spot where the surface layer has more than 35 percent, by volume, rock fragments that are mostly less than 3 inches in diameter in an area that has less than 15 percent rock fragments.  Typically__to__acres.|"297629"
"MT643"|8|"GUL"|"Gully"|A small, steep-sided channel caused by erosion and cut in unconsolidated materials by concentrated but intermittent flow of water.  The distinction between a gully and a rill is one of depth. A gully generally is an obstacle to farm machinery and is too deep to be obliterated by ordinary tillage whereas a rill is of lesser depth and can be smoothed over by ordinary tillage.|"297630"
"MT643"|8|"MPI"|"Mine or quarry"|An open excavation from which soil and underlying material have been removed and in which bedrock is exposed. Also denotes surface openings to underground mines. Typically__to__acres.|"297631"
"MT643"|8|"ROC"|"Rock outcrop"|An exposure of bedrock at the surface of the earth. Not used where the named soils of the surrounding map unit are shallow overbedrock or where Rock outcrop is a named component of the map unit. Typically__to__acres.|"297632"
"MT643"|8|"SAN"|"Sandy spot"|A spot where the surface layer is loamy fine sand or coarser in areas where the surface layer of the named soils in the surrounding map unit is very fine sandy loam or finer. Typically__to__acres.|"297633"
"MT643"|8|"SLP"|"Short, steep slope"|A narrow area of soil having slopes that are at least two slope classes steeper than the slope class of the surrounding map unit.|"297634"
"MT643"|8|"SOD"|"Sodic spot"|An area where the surface layer has a sodium adsorption ratio that is at least 10 more than that of the surface layer of the named soils in the surrounding map unit. The surface layer of the surrounding soils has a sodium adsorption ratio of 5 or less.  Typically__to__acres.|"297635"
"MT643"|8|"STN"|"Stony spot"|A spot where 0.01 to 0.1 percent of the soil surface is covered by rock fragments that are more than 10 inches in diameter in areas where the surrounding soil has no surface stones.  Typically__to__acres.|"297636"
"MT643"|8|"STV"|"Very stony spot"|A spot where 0.1 to 3.0 percent of the soil surface is covered by rock fragments that are more than 10 inches in diameter in areas where the surface of the surrounding soil is covered by less than 0.01 percent stones. Typically__to__acres.|"297637"
"MT643"|8|"WAT"|"Perennial water"|Small, natural or constructed lakes, ponds, or pits that contain water most of the year. Typically__to__acres.|"297638"
"MT643"|8|"WET"|"Wet spot"|A somewhat poorly drained to very poorly drained area that is at least two drainage classes wetter than the named soils in the surrounding map unit. Typically__to__ acres.|"297639"
