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!!

Yeah, mums the word on this. I know better than to go down that road.
I've only got maybe one more day of digging to clean it out and I've almost got a new trail busted through after this last storm. We made it almost halfway and my wife got her snowmobile stuck about three times hehe.
I need to saturate the material really well with water to kill the dust before I can shovel any more, its so bad you can't see your hand in front of your face after the first scoop.
