,' - -- <br />Cj - Cascajo very gravelly sandy loam, 1 to $0 percent slopes. <br />Thais is a deep, somewhat excessively to excessively drained soil <br />on terrace edges and ridges. It formed in gravelly calcareous allu- <br />1 vivm. Slopes are nearly level to steep. Tne average annual preci- <br />pi•Gaticn is about 12 inches, average annual air temperature is about <br />$2 degrees F., and average frost-free season is about 160 days. <br />' Tyi~ically, the surface layer is very dark grayish brown gravelly <br />' sand loam about 3 inches thick. The subsurface is dark grayish <br />brown gravelly sandy loam about 3 inches thick. The underlying <br />' layers to 60 inches grade from white to light yellowish brown very <br />gravelly loartgr sand. Tha soil is calcareous throughout with a zone <br />of high lime content between 6 and 21 inches. The surface layer is <br />' thicker and the zone of high 1 i~,e content is deeper on the nearly <br />level areas. <br />' Abcut 2$ percent of the mapping unit includes the deep loam profiles <br />' of the Kim series, which oaccur isi lox areas, Midway clay loam, 3 to <br />1$?, and shallow soils over interbedded sandstone and shale on the <br />' steep side slopes. <br />' Permeability of the Cascajo soil is rapid. The available water hold- <br />ing capacity is low. Crullying common along steeper breaks. <br />Native vegetation on the nearly level areas is mostly aid and short <br />' grasses. Pinyon and juniper trees are predominant on the steeper <br />' slopes. <br />1 <br />The steep slope o: this soil is the most limiting feature that must <br />be considered when planning construction.
