This scramble is on my to do list. Thanks for the report Rick. Having visited Alison Mine below Iron Mtn. and noted the heavy machinery there, I too marvelled at what it must have taken to get such heavy equipment up to those elevations.
Yeah, getting that iron stuff up there must have been a sight. I haven’t found any references, but I’ve talked to some people that mentioned seeing old photos of aerial cables (cables running from tree to tree) and that technique was used to lift or drag stuff up and into the mountains. Them-thar miner dudes were pretty tough and determined!
I remember seeing another gold mine site indicated on the topo maps just SE of the gun-sight notch along the San Antonio ridge (between Iron and Baldy). This is way above the Allison mine. I’ve thought about checking that mine site once I get back up on the San Antonio ridge again.
Some pretty cool history in the local SoCal mountains.
