The ranch is located south of the Steamboat Mountains between Abilene and San Angelo, where the Big Country region of West Texas unfolds into the Concho Valley. About eight miles north of historic Fort Chadbourne on the Butterfield Stage Line, the landscape is a mosaic of rolling hills and rocky breaks, rich farmland and native prairie grass pastures, mesquite and live oak, prickly pear and yucca. The ranch has interests in cattle, cotton, wheat, and established an excellent horse-breeding program concentrating on Joe Hancock, Blue Valentine & Driftwood bloodlines. Over the last few years the focus has migrated from breeding to performance where those horses excelled in working cow horse, roping, stock horse events, and ranch versatility. In 2009, the Spiller Ranch received the Outstanding Conservation Ranch Award from the Clear Fork Conservation District.
The ranch produces some of the highest-yield dry-land cotton in the area
