MEMBER REVIEW: This is an old DVD and has a few places where it freezes. Stay with it - it clears by itself. This is an instructional video. It has a minimally basic level of production value - way below what we would expect of a TV show. It reminded me of the educational films we would get in science class in grade school. And it seems to be aimed at your average 6th grader in content. It was made in 2009. They use a lot of weird old video from a variety of sources and that may make this DVD worth watching by itself. See the old trains. Once the history is over, they get into the specific geology of the various gold districts in Colorado. They do talk about various associated minerals, and the geological processes that caused the placements to come about. It gets somewhat technical, but it is easily understandable if you are into the geology. They have a couple of placer miners explaining how their operation. Then they get into actual gold mining. All in all it is not too bad, if you can deal with the minimal production values and amateur narrator.
