Hey /an/, I was wondering if any of you know where I can find me some Basalt or granite rocks in ohio. I'm looking to build a sweat lodge and need rocks that can sustain a high heat, and all the local sandstone and river rocks won't work cause that shit will explode. Where should I look? Am I going to have to buy them?

Many thanks in advance.

Travel to Turnov (Czech republic) there are a lot of these rocks..

...but as I know heat resistant bricks will do the trick... or you could look at petrographical maps and find nearest location with these kind of rock...
