    Drift mining was very common.

    Hey Kevinincolorado. Do you know how hard it is to intentionally misspell things.

    Good point! There was quite a bit of drift mining done on a bench Placer just south of where I used to live. I left it out because I didnít want to have to go though all the safety issues associated with burrowing into a hillside that way. I know of two people in Colorado who have did by digging coyote holes into a bench Placer as they followed a pay layer. Yikes!

    Hmm, now that Iíve written this, I feel like I have to add a caution to the article. Thanks for getting me there. This is why I like to share my articles here...always a fresh thought or suggestion. Shame Iím not allowed now that I have a book for sale and such. Ah well, PM if you want a link or other ways to see notifications about my stuff. Peace and ďfind YOUR gold!Ē

    Edit: Update done. Thanks again.

    Why is it called a "bench"?

    Also, there is a place near where I live that kind of fits the description, only when the river is VERY high it is shallowly submerged. I have found gold near there, would this be a place that might have old gold? Or would I have to dig the 20+- feet down to bedrock to find anything?

    Not the first time I have provided too much information. It took 20 years but my previous boss figured out not to as me my opinion unless he wanted a very honest, thorough opinion. Love what you're doing out there Kevin, look forward to seeing some more.

    [QUOTE=RTD-Tech;6014152]Why is it called a "bench"?

    https://en.wikipedia.org/wiki/Bench_(geology). A bench may have remnants of an ancient river channel that is possibly gold bearing (a placer) on it. Look high for river rounded rocks that are out of place. Drainages that cut through the ancient channels may also be gold bearing.

    If it can't be grown, it must be mined!

    Loved the article! I just wish my favorite stomping grounds in the high country had not fallen prey to glaciers, which scrubbed away any such bench placers.
