Does anyone have any experience getting to the Allison Mine going up the gulch, without rappelling?
We tried doing it coming up from Heaton Flats, but as soon as we turned onto the Allison Mine trail, it got way to sketchy; probably “doable”, but with way-too-small margin of error. We decided it simply wasn’t wise to continue.
I still really wanna see the mine though and was looking for other possible ways of getting there.

Sean and I tried to take the Allison Mine trail from Heaton last year and it was in awful shape.

I think your odds are better going up the gulch.

I walked up the gulch last year, and the route was very doable. But that was before the Bridge fire, and the conditions are probably very different now. Report back on conditions if you try to get there!

Thank you for that tip. It is in an awful shape indeed. Especially after the rains and probably the fire.

Yea I saw that trip report if yours and it did indeed look doable based on your photos (not factoring in the damage from the fire). I’m just curious, why does everyone talk about repelling when talking about the route from the gulch?

There are some falls that canyoneers like to descend. The trail goes around.

Did you guys also come back the same way?

I noticed in one of your post you talk about how hard it is to find the start of the trail that goes up the gulch. Is there anyway you’d be kind enough to share the coordinates with me or describe a good way to find it?

I’m sorry to be asking the same question multiple times, but

The route on OSM is and the USGS topo map is close to correct. Stay in the river, and then climb up where those routes on the map say: at the small clearing near the big metal debris piece in the photos in the trip reports. The switchbacks leading up away from the river were a bit indistinct, but there are many workable lines in that area. Expect brush, and wear long pants and sleeves
