HRA provided cultural resources services to the National Park Service (NPS) for the prescribed Matilda Fire, the Colter Bay Water Main Replacement, Moose Water/Wastewater projects, and Gros Ventre Stabilization. These four separate projects were located in Grand Teton National Park, Teton County, Wyoming. The total survey area was approximately 390 acres. HRA conducted background research with the Wyoming State Historic Preservation Office and completed an inventory that included pedestrian survey and shovel testing. A report of the results was also prepared.
