Texas High Plains Sandy Loam & Caliche
Dominant Soil Order: Mollisols / Alfisols
Parent Material: Eolian Silt, Sand, and Ogallala Formation Caprock Caliche
The High Plains (Llano Estacado) regime features vast, nearly level tableland composed of deep, fertile wind-blown sandy clay loams (Pullman and Amarillo series) underlain at depth by the indurated calcium carbonate caliche caprock of the Ogallala Formation. Surface grading and scraper cycle times are among the fastest in the country due to low stone content and gentle topography. However, deep excavation for stormwater retention playas, water storage basins, and municipal trunk lines inevitably encounters dense, white caliche beds that require heavy ripper shanks or rock teeth. High wind speeds during spring demand aggressive dust control and rapid surface compaction to prevent severe wind erosion on open grading sites.

Area-specific FAQ
Do I need to call before digging in Gray County?
