If anyone wants to take on this challenge I would suggest trailing the loop backwards and once at the mine come back the same way. The loop is absolutely not traveled on often and barley even exists. I’ve hiked the full loop before and at places it can be very dangerous where your footing is. Much easier to travel the opposite way up to the mine. Be aware there are still many steep drops and extremely steep switch backs still.

I agree with Julian. The trail is badly damaged, overgrown and dangerous in places. We did manage to get past the mine and find the continuation of the loop - but both safely passing the mine and finding the trail were not obvious. About a mile or so on from the mine we lost it completely and, as it was dry, exited out a gully as the safest option rather than retrace the route. It really is that bad.

Don't go to the mines. The trail to the mines seems like it hasn't been traveled in quite some time. Most of the trail has been wiped out by rockslides. I made the mistake of going this route and more than half way through the trail just ended. We were stranded and had to head all the way back the way we came. It was not fun and we got to our car much past night fall due to this. This trail is DEAD

Hiked up Heaton Flats Trail and took Allison Mine Trail to the mine. Beware the Allison Mine Trail is not maintained, infrequently used and is deteriorating. After the mine (the intersection of the trail and Allison gulch) I was unable to find Allison Gulch trail. I ended up taking AMT back to Heaton Flats Trail. This added time and distance I wasn't entirely prepared for. Afterward I discovered I picked up a few ticks :/ Will try again from East Fork Trail to Allison Gulch to see where it went wrong. Take lights. PS be careful with the mine, one of the shafts in the lower entrance had little oxygen so I exited immediately. Oh and tons of yucca.
