So I went on an adventure looking for rocks and drift wood in the creek on my parents 50 acres.
The adventure called for the use of their sideXside and at one point a kayak just to cross a small portion of deep water mostly for fun! Anyways I found some cool rocks that I want to use in my aquarium I know how to prep and test them from other posts and YouTube.
But being a curious person I thought I would ask to see what they were if anyone knew what they were these are only 4 of about 30 I grabbed. A majority of them look like the first 3 another is the from the creek bottom it's about 2x1' and about 1/8 of an inch thick.
But here is the first batch the rest I left in a barn.
If it helps I love by Cincinnati Ohio!
