Also once known as the Mojave Hilton, I couldn't find any history on the American Flag Mine or the cabin. I first visited the cabin in 2011 before any repairs had been done on it. I stopped by for visits in 2016 and 2022. You can see the work done to the place in my photos.
Volunteers and NPS staff have both made repairs and cleaned up the place (The cabin is inside the Mojave National Preserve). The cabin has a couple of bunk beds and a 55-gallon drum stove and that's it! I don't recommend staying here though. The mice have taken over and there is a definite risk of Hantavirus. The place needs a good cleaning and some mouse-proofing. The cabin does, however, have a great view of the Eastern Mojave Desert and makes for a nice solitary spot to camp.
