Allison Mine

    After we visited Big Horn Mine and another one on the way to Cucamonga Mt. my son Fedor was defiantly excited to explore more mines. Allison gold mine located higher up in Allison Gulch in the south face of Iron Mountain and was worked intermittently from 1915 until about 1942 by George Allison and his three sons. The center tunnel is around 250 feet, not very deep compared to Big Horn.

    Initially I want to do a clockwise loop, but after a mile or so it become apparent that water level in San Gabriel river is too high and current is too swift for safe crossing. Good news we find out about water problem in the morning, not on the way back, that would be a total disaster.

Trail to Allison Mine

Heaton Flats Trail
    The Heaton Flats trail is very good and straight forward, when you get to the saddle turn left where Allison Mine trail starts. It's not maintained and very overgrown, hard and slow going, but with some patience sooner or later you will reach the mine.

Allison Mine in the center
We found and explorer 3 tunnels, not very deep, but still interesting, there was also some artifacts outside, such as old boiler and broken water pipes.

It took us around 10 hours car to car, way longer then Iron Mt. I also was bitten by a tick, which I discovered at home and have to send it to the lab to make sure I did not get a Lyme disease (I did not).
