You guy's will just have try the Arkansas stone. After 8 years it is still doing great in my first pond with really no signs of eroding. Unfortuantely our MO sandstone is junk like I said.
I just redid part of a pond that is 10 years old and was built with a lot of limestone that was turning to mush.
All the stone is just a regional thing! Our weathered limestone is junk and Wisconsin has some VERY dense limestone. I wish I had a yard and the money to buy and store a lot of stone from around the country do to some being cheaper and better than our native stone.
