SOIL MAP UNIT 27-7 



Soil Map Unit 27-7 occurs along the flood- 

 plains, terraces, and sideslopes adjacent to 

 Beaver Creek. Soils are formed in cobbly, 

 sandy glacial till and outwash that have 

 been deposited and sorted by glacial 

 meltwater. 



Soils have medium-textured surface layers. 

 Surface layers form in volcanic ash influ- 

 enced loess, with subsoils and substrate 

 containing 50% to 80% rounded rock 

 fragments. Surface horizons are loamy- 

 skeletal and have a brown gravelly silt 

 loam surface layer 4" to 8" thick. The 

 upper subsoils are light yellowish brown, 

 extremely cobbly sandy loam approxi- 

 mately 9 inches thick. The lower subsoil is 

 light olive brown extremely cobbly sandy 

 loam. Substratum is extremely cobbly 

 loamy sand to depths of 60 inches or more. 



• SOIL MAP UNIT 14-3 



Soils included in Map Unit 14-3 are formed 

 in lacustrine sediments deposited in 

 topographic depressions and on glacial 

 moraines. In general, these soil types have 

 fluctuating water tables that are at or near 

 the ground surface during spring and early 

 summer. As a result, soils commonly occur 

 in riparian areas and are highly sensitive to 

 certain management practices due to the 

 high soil moisture and low bearing 

 strength. Additional site-specific BMPs are 

 recommended for operations on Unit 14-3.
