197 - Yainac loam, to 2 percent slopes. This deep, well 

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

 to 2 percent. 



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

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

 more is a loam that has strau of fine sandy loam and silt 

 loam. 



Permeability is moderate and available water capacity is 

 about 7 inches in the upper 48 inches. 



TTussoil is well suited to irrigated crops. This map unit 

 is class 2 irrigated. 



198 -Yainac loam, 2 to 8 percent slopes. This deep, well 

 drained soil is on fans and uplands. It formed in colluvium 

 and alluvium derived from loamy sedimentary beds. Slope 

 is 2 to 8 percent. 



Thesoil profile to a depth of48 inches or more is a loam. 



Permeability is moderate and available water capacity is 

 about 8 inches in the upper 48 inches. 



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

 class 3 irrigated. 



199 - Yamac loam, 8 to 15 percent slopes. This deep well 

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

 and in colluvium derived from loamy sedimentary beds. 



Thesoil profile toa depth of48 inches or more isa loam. 



Permeability is moderateand available water capacity Is 

 about 8 inches in the upper 48 inches. 



This map unit is poorly suited to irrigated crops because 

 of inclusions of shallow soils over loamy sedimentary beds. 

 This map unit is class 6 irrigated. 



20 1 - Yamac-Bimey complex; 2 to 8 percent slopes. This 

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



This unit is about 60 percent Yamac loam and 40 

 percent Bimey channery loam. The Yamac soil formed in 

 alluvium and in coQuvium. The Birney soil formed in 

 colluvium derived from baked sandstone and shale. 



The Yamac soil is deep and well drained. The surface 

 layer isa 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 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 6 inches thick. The substratum to a 

 depth of 48 inches or more is a very channery loam. Perme- 

 ability is moderate and available water capacity is about 3 

 inches in the upper 48 inches. 



This map unit is suited to irrigated cropw. Bimey soils 

 have low available vrater capacity. Shallow soils over baked 

 sandstone and shale are included. TTiis map unit is class 3 

 irrigated. 



202 -Yamac-Bimey complex, 8 to 15 percent slopes. This 

 map unit is on uplands. Slope is 8 to 1 5 percent. 



This map unit is about 55 percent Yamac loam and 45 

 percent Bimey channery loam. The Yamac soil formed in 

 alluvium and in colluvium derived from baked sandstone 

 and shale. 



The Yamac soil is deep and well drained. TTie surface 

 layer isa 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 capacity is about 8 inches in 

 the upper 48 inches. 



The Birney soil is deep and well drained. The surface 

 layer is a channery loam about 4 inches thick. The subsoil is 

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

 depth of 48 inches or more is a very channery loam. Per- 

 meability is moderate and available water capacity is about 

 3 inches in the upper 48 inches. 



This map unit is pooriy suited to irrigated crops because 

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

 clusions ofshallow soil over baked sandstone and shale. This 

 map unit is class 6 irrigated. 



205 - Yamac-Busby complex, 2 to 8 percent slopes. This 

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



This unit is about 55 percent Yamac loam and 45 

 percent Busby fine sandy loam These soils formed in
