CATESBY SERIES


The Catesby series consists of very deep, well drained, moderately permeable soils that formed in calcareous loamy colluvium from the Ash Hollow or Kimball Members, Ogallala Formation of Miocene-Pliocene age. These soils are on gently sloping to steep hillslopes and colluvial aprons in the Southern High Plains, Breaks (MLRA 77E). Slope ranges from 1 to 20 percent. Mean annual precipitation is about 530 mm (21 in), and mean annual temperature is about 15 degrees C (59 degrees F).

TAXONOMIC CLASS: Coarse-loamy, mixed, superactive, thermic Aridic Calciustolls
