alluvium and in colluvium derived from loamy and sandy 

 sedimcncary beds. 



The Yamac soil is deep and well drained. The surface 

 layer is a loam abouc 3 inches thick. The underlying material 

 to a depth of 48 inches or more is a loam. Permeability is 

 moderate and available water capacity is about 8 inches in the 

 upper 48 inches. 



The Busby soil is deep and well drained. The soil profile 

 to a depth of 48 inches or more is a fine sandy loam. Per- 

 meability is moderately rapid and available water capacity is 

 about 5 inches in the upper 48 inches. 



This map unit is poorly suited to irrigated crops because 

 of inclusions of rock outcrop. This map unit is class 6 irri- 

 gated. 



208 - Yamac-Del point loams, 4 to 1 5 percent slopes. This 

 map unit is on uplands. Slope is 4 to 1 5 percent. 



This unit is about 55 percent Yamac loam and45 percent 

 Delpoint loam. The Yamac soil formed in alluvium and in 

 colluvium. The Delp>oint soil formed in residuum derived 

 from loamy sedimentary beds. 



The Yamac soil is deep and well drained. The surface 

 layer is a loam about 4 inches chick. The underlying material 

 to a depth of 48 inches or more is a loam. Permeability is 

 moderateand available water capacity is about 8 inches in the 

 upper 48 inches. 



The Delpoint soil is moderately deep and well drained. 

 The surface layer is a loam about 6 inches thick. The under- 

 lyingsoil material is a loam. Below this, coadepth of48 inches 

 or more, are loamy sedimentary beds. Permeability is mod- 

 erate and available water capacity is mainly 3 to 5 inches, 

 depending on the depth to the loamy sedimentary beds. 



This map unit is poorly suited to irrigated crops because 

 of depth to loamy sedimentary beds. This map unit is class 6. 



209 - Yamac-Redcreek loams, 2 to 1 5 percent slopes. This 

 map unit is on uplands. Slope is 4 to 1 5 percent. 



This unit is about 50 percent Yamac loam and 50 percent 

 Redcreek loam. The Yamac soil formed in colluvium. The 

 Redcreek soil formed in residuum derived from sandstone. 



The Yamac soil is deep and well drained. The surface 

 layer is a loam about 4 inches thick. The underlying material 

 to a depth of 48 inches or more is a loam. Permeability is 

 moderate and available water capadcy is about 8 inches in 

 the upper 48 inches. 



The Redcreek soil is shallow and well drained. The soil 

 material is loam. Below this, to a depth of 48 inches or more, 

 is sandstone. Permeability is moderately rapid and available 

 water capacity is about 2 inches. The effective rooting depth 

 is limited by the sandstone at a depth of 1 to 20 inches. 



This map unit is poorly suited to irrigated crops because 

 of the shallow depth to sandstone of the Redcreek soil. This 

 map unit is class 6 irrigated. 



2. Soils on fans and uplands. This group consists of fifteen 

 map units. Slope is 4 to 25 percent. Soils are shallow to deep. 

 They formed in alluvium, colluvium, baked sandstone and 

 shale, and residuum from loamy and sandy sedimentary 

 beds. 



These map units are not suited to irrigated crops due to one 

 or more of the following: steepness of slope, shallow depth, 

 to baked sandstone and shale, sedimentary beds and 

 low available water capacity of the soils. These map units are 

 class 6. 



The following map units are in this group.
