This is a cyclic soil and undisturbed areas have gilgai microrelief with microknolls 4 to 18 inches higher than microdepressions. Distance between the center of the microknoll and the center of the microdepression is about 5 to 15 feet. The microknoll makes up about 25 percent, the intermediate, or 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 less than 150 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 greater than 0.07. Where redox features exceed 3 percent, they occur in less than 25 percent of each pedon. The range in characteristics represents 50 percent or more of each pedon unless otherwise stated. These are the Bleiblerville , Branyon , Burleson , Clarita , Dimebox , Fairlie , Heiden , Houston Black , Leson , Luling , Ovan , Sanger , Slidell , Sparenburg, and the Watonga series. Similar soils also include the Chapel , Lazbuddie , Lockney , Ranco , and Randall series.
