These projects were all conducted in very remote areas, which often required crews to pack in or use helicopters to stage the equipment and materials needed for the closures. Extreme heat required close monitoring of workers to ensure worker safety. Our crews received training in preventing the spread of White-nose Syndrome, as well as avoiding the endangered desert tortoise and leaf-nosed bats. They were also careful to avoid damaging cultural resources at the various sites.
