"MT041"|11|"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 0.5 to 5 acres.|"287175"
"MT041"|11|"MAR"|"Marsh or swamp"|A water saturated, very poorly drained area that is intermittently or permanently covered by water.

"MT041"|11|"MIS"|"Miscellaneous water"|Small, constructed bodies of water that are used for industrial, sanitary, or mining applications and that contain water most of the year. Typically 0.5 to 5 acres|"287177"
"MT041"|11|"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 0.5 to 5 acres.|"287178"
"MT041"|11|"RUB"|"Rubble land"|Area consisting of cobbles, stones, and boulders. Most areas are commonly at the base of mountains, but some are deposits left on mountains by glaciation or by periglacial processes. Typically less than 5 acres.|"287179"
"MT041"|11|"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 0.5 to 5 acres.|"287180"
"MT041"|11|"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 0.5 to 5 acres.|"287181"
"MT041"|11|"SEP"|"Seep area"|A generally small area, where water percolates slowly to the land surface. Typically less than 5 acres.|"287182"
"MT041"|11|"SHA"|"Shallow area"|A soil that is less than 20 inches deep over bedrock or to other materials that restricts the penetration of plant roots. Typically less than 5 acres.|"287183"
"MT041"|11|"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.|"287184"
"MT041"|11|"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 0.5 to 5 acres.|"287185"
"MT041"|11|"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.|"287186"
"MT041"|11|"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 0.5 to 5 acres.|"287187"
"MT041"|11|"WAT"|"Perennial water"|Small, natural or constructed lakes, ponds, or pits that contain water most of the year. Typically 0.5 to 5 acres.|"287188"
