Exposed bedrock maps?

[Ohiogoldfever]

Anyone know of a online service that may help locate areas of exposed bedrock?

Sounds like a silly question I’m sure. Being in Ohio it could be 75 feet below over burden, or some places are exposed.

There are no silly questions, except the ones I ask. Can I ask why you want this information. Looking for Gold??

I don't know about other states but in Misery they have our Department of natural Resources that has a Index of publications that shows every book / paper / test's that they did on public $$$$$ and some of these articles , publications are for free and some have a reasonable cost for their info ! Try goggling this info for your state . Usually there is a TON of publications there. Misery also has a big book that has each county's Geological make up showing the mineral and rock types and I beleive they also listed the depth to bedrock ! Good Luck and let's hear what you've found out for your situation !

Contacting a well drilling company will also know the average depth to bedrock IF they have the time to tell you ! QAnd say "Thankyou" for what ever info you do or don't get !

Thanks for the reply’s guys.

Yes, I am a gold prospector.

I will see if I can find. I have been able to find a fair bit of geologic info just nothing mapping bedrock outcroppings. I have found quite a few outcroppings just nothing that seems to be holding gold. I was just hoping to find something to help me locate more places to prospect.

Jim Straight before he passed away, wrote various books and articles for mining journals. I had for years been on the same gold prospecting forum with him. Once Jim mailed me a copy of a mining journal with an article he wrote. I'm thinking it may have been a 2 part article (meaning I would have 2 journal copies). I need to check see if 1 or 2 issues. He said they would send him a free copy for every article written (that is what these were).

I can tell you what happened to concentrate the gold. According to the article, water formed from glacier melting and edges became like a giant sluice box. You find out where gold has been already found in your state. Now other areas with heavy overburden will produce hardrock ore specimens. I have found right on property at home, large chunks of quartz vein (look exactly like what you see around Quartzsite, AZ).

You belong to gpaa? They may be of help.

I don’t, I’ll look into that.

Years back when I was in the gpaa I went to a outing at the Swanks property with the Ohio Gold Prospectors group ( Ohiooutdoorsman.com) on yahoogroups and I was up there for about a week and traveled to their claims to try them out. Gold in Ohio is real fine like in most mid-western states . And as yo know , the Glaciers ground "our mountains" down and filled in the valleys DEEP ! Good Luck and keep us informed as to how you do !

There is supposed to be a place in Ohio, you can dredge for pickers.

Yes sir the gold here is fairly fine. My area (Greene county) has some decent spots. It’s hard for me to find anything better than 5-10 bits per pan. Everything is flood gold that I get from gravel bars and rock piles.

Hoping to find a few outcroppings to prospect this summer. Just to see if anything slightly larger, or high spec counts can be found.

Records of gold being found here are fairly sparse. I’ve found a few publications but nothing that really speaks volumes.

russau nailed it with depth to bedrock maps. They are ubiquitous.​

Easily accessable public places to see exposed bedrock is highway road cuts.

 

[traveller777]

I don’t, I’ll look into that.

And a quick search I did showed historical gold areas

I don’t, I’ll look into that.

They may be of help. And a quick search I did for historical gold sites in Ohio showed some locations.

Ohio (and most other states) offer these maps for free.

The ODNR Division of Geological Survey has been creating bedrock geologic maps for the state of Ohio since 1839.

Good job, Clay.

Good job, Clay.

Thank you for the link. I have looked over most of these but don’t see any that specify exposed bedrock sections. I see lots of info on bedrock types, ages, geology and glaciated areas.

My best spots always neighbor a gravel pit. I suppose if I could find the edges of a gravel filled depression that might be my best bet..... crevices and productions to hold the gold and a solid gravel body up stream to supply the eroded materials.
