Our family hiked up to the Roosevelt Mine entrance. Is that the area we’re looking at? It’s sealed, but you can walk in a little bit. Lots of old walls and foundations scattered around it. The power house (if I remember correctly) for the mine was at the base of the hillside. Its four walls were still quite prominent. We found the remains of a “sluice”? Not sure what to call it. There were long rows of metal circles that once held what I would guess to have been a wooden pipeline. Part of the trail walked on the remains of the pipeline (the circles were cut open here). Part of the hiking trail was on an unused road of sorts too. Can’t remember if I have any photos.
