Thanks for an informative video for rockhounds. Yes, most of Michigan is known for it's sedimentary rock but this is not the whole geologic story. It should be mentioned that beneath a good portion of the lower peninsula, the basement rock is volcanic in origin ... igneous, rhyolite and other metamorphic rock. Though this rock is not at the surface for rockhounding, the formations created by The Mid Continent Rift and Eastern Rhyolite Province volcanics shouldn't be ignored. Glacial/sedimentary geology has become Michigan's formal geology, when what lies beneath all the till is way more interesting!
I think there's more to Michigan than has been reviewed because i live in one of those areas where it says really there's nothing here to collect, but I have to strongly disagree. In this particular area, we find very nice pieces of lava glass, gems, minerals, Iron Ore & more & I have a huge collection to prove it.
Keep these informational videos about the Great Lake Region coming they are very informative 👍
Keep these coming, great video!
Thank you for the info.

Please check out our Michigan Basin video as well as the ongoing Michigan Geology series! We cover a lot of this and more.
