adcpth of48 inches or more, is hard sandstone. Permeability 

 is moderate and available water capacity is about 2 inches. 

 The effective rooting depth is limited by hard sandstone at 

 a depth of 1 to 20 inches. 



The Shambo soil is deep and well drained. The soil 

 profile to a depth of 48 inches or more is a loam. Permeabil- 

 ity is moderate and available water capacity is about 8 inches 

 in the upper 48 inches. 



The map unit is poorly suited to irrigated crops because 

 of the shallow depth to hard sandstone of the Casmcr soil. 

 This map unit is class 6 irrigated. 



62 - Chinook fine sandy loam, 2 to 8 percent slopes. This 

 deep, well drained soil is on fans and uplands. It formed in 

 alluvium on fans and in eolian material on uplands. Slope 

 is 2 to 8 percent. 



The soil profile to a depth of 48 inches or more is a fine 

 sandy loam. 



Permeability is moderately rapid and available water 

 capadcy is about 6 inches in the upper 48 inches. 



This soil is suited to irrigated crops. This map unit is 

 class 3 irrigated. 



64 - Cooers loam, 2 to 8 percent slopes. This deep, well 

 drained soil is on fans and uplands. It formed in alluvium or 

 in colluvium derived from baked sandstone and shale. Slope 

 is 2 to 8 percent. 



The surface layer of this soil is a loam about 5 inches 

 thick. The underKnng material to a depth of 48 inches or 

 more is a loam. 



Permeability is moderate, and available water capacity 

 is about 8 inches m the upper 48 inches. 



This soil is suited to irrigated crops. This map unit is 

 class 2 irrigated. 



65 - Cooers-Bimey complex, 2 to 8 percent slopes. This 

 map unit is on uplands. Slope is 2 to 8 percent. 



This unit is about 60 percent Cooers loam and 30 

 percent Bimey channcry loam. The Cooers soil formed in 



alluvium. The Birncy soil formed in colluvium, derived 

 from baked sandstone and shale. 



The Cooers 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 

 moderate and available water capacity is about 8 inches in 

 the upper 48 inches. 



The Bimey soil is deep and well drained. The surface 

 layer is a channery loam about 5 inches thick. The subsoil is 

 a channery loam about 8 inches thick. The substratum to a 

 depth of 48 inches or more is mainly an extremely channcrv 

 loam. Permeability is moderate and available water capacity 

 is about 3 inches in the upper 48 inches. 



This map unit is poorly suited to irrigated crops because 

 of low available water capacity of the Bimey soil and inclu- 

 sions of shallow soiU over baked sandstone and shale. This 

 map unit is class 6 irrigated. 



66 - Cooers- Yamac loams, 2 to 8 percent slopes. This map 

 unit is on fans and uplands. Slope is 2 to 8 percent. 



This unit is about 50 percent Cooers loam and 50 

 percent Yamac loam. They formed in alluvium and collu- 

 vium derived from baked sandstone and shale from loamy 

 sedimentary beds. 



The Cooers soil is deep and well drained. The surface 

 layer isa loam about 4 inches chick. 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 Yamac soil is deep and well drained. The surfece 

 layer isa loam about 5 inches thick. The underlying material 

 to a depth of 48 inches or more is a loam that has strata of 

 fine sandy loam and silt loam. Permeability is moderate and 

 available water capacity is about 8 inches in the upper 48 

 inches. 



These soils are suited to irrigated crops. This map unit 

 is class 2 irrigated. 



81 - Floweree silt loam, to 2 percent slopes. This deep, 

 well drained soil is on terraces. It formed in alluvium. Slope 

 is to 2 percent.
