Between August 9 and September 19, 2009, Atkins conducted data recovery operations at the Hawkwind site (41HS915) under Texas Antiquities Permit No. 5356. Data recovery at the site was initiated as the location was subject to proposed highway improvements. The field effort included mechanical and manual unit excavation within a single 24-unit excavation block. Mechanical excavation was conducted with a Grade-All, and fill was passed through a motorized screening bucket affixed to a Bobcat Skid Steer Loader. Approximately 139 cubic meters (m3) of fill was removed in the excavation block during data recovery operations at site 41HS915. About 123 m3 of sediment was mechanically excavated, and 66 m3 of fill was mechanically screened. Sixteen cubic meters of sediment was manually excavated, and 12.50 m3 of sediment was screened by hand. The use of mechanical excavation equipment and motorized screen at Hawkwind was a strategy that was aimed at maximizing data return at a relatively low-density, poorly stratified archeological site while avoiding the cost and time-consumption associated with traditional excavation methods.
