I've been paying attention to this slope in particular. There are a couple of "knobs", or buttes like this that I've hunted over the years that are archeological sites yet to be "discovered".
East of my favorite caribou hunting grounds lie the Tangle Lakes Archeological District. The feds have established access restrictions and explicit bans on removing artifacts which are everywhere to be found without the need for a shovel. Before this 'district' was established, plenty of folks combed the area and took artifacts home with them.
The three areas I like to hunt are less accessible, so exponentially fewer people visit the areas. One of these has been surveyed by archeologists and documented, but since few visit the ridge, no effort to restrict access has been attenpted yet.
All these sites feature primarily spear tips and shafts, and they are all higher elevations with outstanding views of migrating caribou routes.
