APPENDIX B 

 SOILS IN THE TONGUE AND ROSEBUD DRAINAGES 



1 . Soils on floodplains and low terraces. 



These deep, well-drained soils are on nearly level flood- 

 plains and low terraces along theTongue River and Rosebud 

 Creek. The major soil series include Glendive, Hanly, 

 Harlem, Havre and Straw. They formed in alluvium. Some 

 soils are excessively drained and underlain by coarse or mod- 

 erately coarse alluvium. Slopes range from to 2 percent. 



2. Soils on fans, terraces and uplands. 



These deep, well drained soils are on nearly level terraces, 

 slopi ng fans and moderately steep uplands. They occur above 

 the floodplain and adjacent to the valley floor of theTongue 

 river and Rosebud Creek, Landscape dis.section is a common 

 feature adjacent to the valleys. The major soil series include 

 Bimey, Cooers, Kremlin, Lonna, Shambo and Yamac They 

 formed in alluvium and coUuvium. Slopes range from to 25 

 percent. 



3. Soils on sedimentary uplands. 



These shallow to deep, well drained soils are on gently 

 sloping to moderately steep uplands. The major soil series 

 include Busby, Cabbart, Cambeth, Castner and Delpoint. 

 They formed in colluvium and weakly consolidated loamy 

 and sandy sedimentary beds. Slopes range from 2 to 25 

 percent. 



4. Soils on dissected sedimentary uplands. 



These shallow to deep, well drained soils are on strongly 

 sloping to very steep dissected uplands. The major soil series 

 include Bitton, Cabbart, Cambeth, Delpoint and Yawdim. 

 The dissected landscape has barren sideslopes, escarpments, 

 narrow ridges, rock outcrops and deeply entrenched cou- 

 lees. Geologic erosion is very active in the sedimentary beds. 

 Slopes range from 8 to 70 f)ercent.
