Different agate

[Muskiefool]

I found these in a sand pit in SE MN about 12-14 years ago just wondering if anyone has any ideas they are a fortification type and weigh about 4-6# a piece, the detail seems minimal yellowish and white but both are pretty well roughed up from the sand bed I guess, they were the only 2 I found in about a million yards of sand.

They look real interesting, but need better focus, they're way too blurry to appreciate properly...

Veerrry interesting...thanks for the clearer pics...

The top two pictures of the one look more Stalagtite, Stactite, in formation...

The bottom two pictures of the other look more Agatey...

Can you post a couple pictures of the sides...

The SE area has some weird formations...I found some crystally formations falling out of the side of a hill there once, that looked a lot like white Coral...very heavy too...

I've heard them referred to as "prairie agates" and I have a few in a bucket somewhere.
