I was mostly at work.
Unrelated, I went camping on the neighboring forest to where I'm working on this season near a peculiar area doing a little thing some people on another forum I frequent call a S*T*A*L*K*E*R challenge. Goal of it is to combine camping with urbex and seek out cool things, also occasionally to seek out cryptids or straight up anomalous events.
Anyway, picture the setting, four corners region of the US, high desert with mostly sandstone canyons, scrubby oaks, short pinyons and the occasional stunted ponderosa pine. In a more flattened out canyon in the early 1950s, someone got a wild hair up their brain and decided to use a nuclear device to fracture oil and gas deposits....
It went about as well as one could be expected, the pocket that was created was mostly glass and sealed the majority of the fracturing, and what natural gas was yielded was ultimately irradiated and unusable.
fast forward to 2018, the majority of the buildings are gone, there's an interactive interpretive display, and a concrete shed that allows for some cover. That's where I ultimately made my camp bringing with me a tent, some food a compound bow because I was able to get archery tags for turkey, and an sks rifle in case I needed to deter something since mountain lions and bears are not unknown in the area. Friday was uneventful, saturday too, though I did got hiking between downpours and nailed a wild turkey with my compound bow. On Sunday morning as I was packing up I found an odd rock, geologically it made no sense for it to be there... so I kept it.
I've tentatively id'd it as Silica Carbide and am fairly certain it's not radioactive but I plan to take it in to the office on Monday when the district geologist can take a look at it (also we have friskers there and I can confirm whether it's not radioactive or if it's been slowly killing me this whole time)
