I went to the coordinates provided in the Dyrt app, and nothing was there except a mine. I had absolutely zero cell service (not even 1x) in this valley with Verizon. I’m pretty confused what the other comments about because I didn’t see anything. If you attempt, definitely download maps offline in advance.
Edit: I moved on to another site but now, looking at the coordinates in the Dyrt app and the location when searching Google Maps, they are very different. Perhaps the Google Maps location is where it actually is.
