Green energy project in the western US, on ancestral tribal land so we were advised to keep our eyes out for historical sites, and to let tribal advisors/inspectors know if we found any. Well, we (my group was a subcontractor, and some of the first out pioneering through new areas) found some ancient hunting blinds on either side of a saddle through a ridge, complete with trash pits/stone knapping shards and even some paintings on the walls. We advised the General Contractor as the tribal rep wasn't onsite that day. The GC told us to forget what we saw and they'd send a bulldozer over to wipe out the site, as the blinds were right in the planned route of an access road and they didn't want the hassle of a redesign. Hell to the no, we got hold of the tribal rep outside the chain of command and let them know what was up. They rushed to the site issued a very stern stop work order (either you stop your equipment so we can assess this find, or you will load your shit up and get off our land) and went through the proper processes. A realignment of the road did happen, and the GC got annoyed at us, but fuck them. Later, the same tribal inspector gifted my boss with a hand-knapped obsidian spear head as thanks.
