I found these while rockhounding in the lower peninsula (specifically Lakeport State Park, MI) and couldn’t figure out what they were. Any help is greatly appreciated!

Hello, I found these also while rockhounding in Eugene, Oregon. They are super reflective and as I was taking them out of the ground, broke incredibly easily. I couldn’t figure out what they were, but found a bunch of specimens. Thank you so much for your help!

Hello,

I found this in Eugene, Oregon and have no idea what it is. Besides the white, there are also little splotches of tiny black crystals. Any help in identifying would be greatly appreciated!

Hello everyone,

This is was found in Lakeport State Park, near Port Huron, Michigan. By chance do you any of you know what this is? I included some pictures of it wet and dry. Thank you!
