This is a cyclic soil and undisturbed areas have gilgai microrelief with microknolls 5 to 18 inches higher than microdepressions. Distance between the center of the microknoll and the center of the microdepression is about 5 to 20 feet. The microknoll makes up about 25 percent, the intermediate area between the knoll and depression about 50 percent, and the microdepression about 25 percent. Cracks open and close each year, except during higher than normal rainfall years, and remain open for 150 to 210 cumulative days during most years. When dry, 0.4 to 3 inch wide cracks extend from the surface to a depth of 40 inches or more.
Cracks are more prominent in the microdepressions.
COLE is greater than 0.07. The range in characteristics represents 50 percent or more of each pedon unless otherwise stated. Similar soils are the Chapel , Lazbuddie , McLean , Ranco , Randall , and Sparenburg series. These are the similar Lofton , McLean and Randall series and also Estacado , Olton , Pantex , Pep , Portales , Posey , and Pullman series. Lofton soils are on similar landscape positions and have an argillic horizon.
