"MT636"|10|"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 1 to 5 acres.|"262506"
"MT636"|10|"WAT"|"Perennial water"|Small, natural or constructed lakes, ponds, or pits that contain water most of the year. Typically 0.5 to 5 acres.|"262505"
"MT636"|10|"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 1 to 5 acres.|"262504"
"MT636"|10|"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 0.5 to 5 acres.|"262503"
"MT636"|10|"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 1 to 5 acres.|"262502"
"MT636"|10|"SLI"|"Slide or slip"|A prominent landform scar or ridge caused by fairly recent mass movement or descent of earthy material resulting from failure of earth or rock under shear stress along one or several surfaces. Typically 1 to 5 acres.|"262501"
"MT636"|10|"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 1 to 5 acres.|"262500"
"MT636"|10|"SAL"|"Saline spot"|An area where the surface layer has an electrical conductivity of 8 mmhos cm more than the surface layer of the named soils in the surrounding map unit. The surface layer of the surrounding soils has an electrical conductivity of 2 mmhos cm or less. Typically 1 to 5 acres.|"262499"
"MT636"|10|"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 1 to 5 acres.|"262498"
"MT636"|10|"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 1 to 5 acres.|"262497"
"MT636"|10|"MAR"|"Marsh or swamp"|A water saturated, very poorly drained area that is intermittently or permanently covered by water. Sedges, cattails, and rushes are the dominate vegetation in marshes, and trees or shrubs are the dominant vegetation in swamps. Not used in map units where the named soils are poorly drained or very poorly drained. Typically 1 to 5 acres.|"262496"
"MT636"|10|"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.|"262495"
"MT636"|10|"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 1 to 5 acres.|"262494"
"MT636"|10|"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 1 to 5 acres.|"262493"
"MT636"|10|"ESO"|"Escarpment, nonbedrock"|A relatively continuous and steep slope or cliff, which generally is produced by erosion but can be produced by faulting, that breaks the continuity of more gently sloping land surfaces. Exposed earthy material is non soil or very shallow soil.|"262492"
"MT636"|10|"ESB"|"Escarpment, bedrock"|A relatively continuous and steep slope or cliff, which generally is produced by erosion but can be produced by faulting, that breaks the general continuity of more gently sloping land surfaces. Exposed earthy material is hard or soft bedrock.|"262491"
"MT636"|10|"ERO"|"Severely eroded spot"|An area where on the average 75 percent or more of the original surface layer has been lost because of accelerated erosion. Not used in map units that are named severely eroded, very severely eroded, or gullied. Typically 1 to 5 acres.|"262490"
"MT636"|10|"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 1 to 5 acres.|"262489"
"MT636"|10|"BLD"|"Boulders"|Areas of surface rock fragments greater than 23 inches in diameter. Typically less than 5 acres.|"262488"
