Some hikers in Utah discovered this elaborate shelter. No one seems to be occupying it at the moment.
Here's what they wrote: "Went in an epic hike last weekend up a mountain and into a canyon that has no trails and is crazy steep and rugged. Wouldn’t surprise me if we were the first ever to do the hike. If not the first altogether, then I would bet the first to do it in the winter. Found one structure about 10min from the parking lot, but that was it. There were a few other small things along the way, but you had to use your imagination to think they were really anomalous."
