Areas of cultural site damage.
Area 8 sample excavation showing depth of mine waste (upper 10 cm) and intact cultural soils beneath.
Grader destroying Area 8 cultural deposit below the mine waste layer.
9-26-06 storm drain trench miss-placed outside of the area where data recovery excavations had taken place.
Area 11 unmitigated water line trench through cultural soil.

Area 8: Lot 28 Water Truck Road Grading

The 0.8 cubic meter data recovery sample effectively mitigated damage to 13.8 cubic meters of cultural site soil.  However the EPA’s extensive grading into intact archaeological soils caused 43.2 cubic meters of damage.  This means that 29.4 cubic meters of damage occurred to this part of the site without any mitigation (violation of protocol items #5 and #7).

On 9-26-06, excavation of the storm drain trench damaged intact portions of data recovery program designed to recover a statistically valid sample of the area to be disturbed.  This mitigation included the excavation of 7 data recovery units within the trench alignments.  Project surveyors provided actual storm drain trenching was conducted, the trench was not on the same alignment provided for the archaeological work, thereby destroying a portion of the site that had not been mitigated (violation of protocol items #5 and #7).

Unknown volume of cultural soil damaged.

Area 10: Lot 26 Soft Spot Grading (no photos obtained)

On 10-2-06, a Tribal monitor called to report that excavation was taking place within undisturbed cultural soils in front of Lot 26.  This work was apparently done to remove a ?soft spot? that had occurred due to over-watering by the water trucks.  Based on reports from John Holson and Sandy Thomas, the hole was 5 meters by 6 meters and 1 meter deep (violation of protocol items #5 and #7).  Ms. Thomas said that the soils removed contained historic glass, metal and clamshell.

Approximately 30 cubic meters of cultural soil was destroyed with no mitigation.

Area 11: Lot 23 Water Line Trenching

On 10-4-06, excavation for a water line connection was conducted within cultural site soil without the benefit of an archaeological monitor (violation of protocol items #1, #5 and #7). ?Bones were encountered.

Unknown volume of cultural soil damaged.

Unmitigated Cultural Resource Damage Between August 22nd and October 4th, 2006

Based on the above listed violations of the excavation protocol, a minimum of 913 cubic meters of cultural soil was destroyed with no mitigation during the Phase 1B portion of the cleanup project.
