New Members Upnorth Posted July 29, 2021 New Members Share Posted July 29, 2021 Found this near a lake in polk county Wisconsin. There seems to be a somewhat unusual pattern on it. Can anybody identify this? I can get more photos and dimensions if needed. Thanks a bunch! Link to comment Share on other sites More sharing options...
New Members Upnorth Posted July 30, 2021 Author New Members Share Posted July 30, 2021 Here's some additional photos with measurements. Is this anything? Link to comment Share on other sites More sharing options...
Rockwood Posted July 30, 2021 Share Posted July 30, 2021 This brings to mind (not to be confused with an identification) a site I collect from. It's near the northern side of the Hardwood Mt. formation, now a poorly exposed nub, quite remote from the mountain. A few fossils there are fantastically well silicified, but most are disappointing when studied under magnification. Some are little more than what I take to be colloidally deposited silica, or the remnants of ash. Link to comment Share on other sites More sharing options...
