Strange cave found Options

[johnnybravo300]

We found a strange opening and I spent a few hours today digging the entrance hole out. It's full of bedding and rat chit a few feet deep with the bottom foot pretty compacted.
There isn't any mineralization around there at all that I've ever seen. Not even quartz. The rock its dug into is volcanic breccia type sedimentary i believe. It's fairly softish and crumbly.
There is an old cabin ruin up the canyon about 100 yards away but its barely visible now with only the bottom course of logs almost covered with earth. This cabin has almost rotted away entirely and most cabins I find are still standing somewhat. It may be way old. I haven't detected it yet but I will.
I took a rake with me today to open up the hole enough to crawl in and it was kinda sketchy. It opens up just inside the hole and goes straight for about 12 feet, then there's a small room to the right. There is alot of nesting material on the floor as you can see.
It was hammered out with steel tools as I can see the chisel marks scraping deep and its not natural of course.
It will take time to clear it out before I can find the treasure but I'll keep you up to date. Or not!!

Not much new there and I'm not sure what I'm even looking at. I dug it out and took a bud there with his p.I. detector once spring thawed but it was full of flying insects and he didn't want to enter. I haven't been back since then but it looked like they were digging out the seam between two different breccias. There are quartz grains within. I found a bunch of other drill holes in the rock face all across there possibly from the same people.
The darkened rock is natural I believe, and moisture stained but I did find mineralization in the area so they must have seen something that interested them.
Or they wanted me to think that, and there's a big treasure chest near by!
