Yes, this site is intended to be fun.

I've been fascinated with Earth science --especially geology-- my entire life.  I decided to deepen my knowledge using my home state as my lab while sharing what I learn using an online GIS app and this blog.

Before you follow along, please read below:

This blog and it's companion GIS app bring together geologic data from reliable sources including the Wisconsin Geological and Natural History Survey (WGNHS), various Wisconsin state agencies, U.S. Geological Survey (USGS), and various universities. Most of the mapped features include source/reference information inside the popup window. I am making every effort to give credit where credit is due. If you notice that I failed to credit someone else's work, please send me a note so I can correct the omission.

This information is compiled from sources believed to be reliable, but is distributed on an "as is" basis. I'd be happy to hear your thoughts if you feel something I write on this blog was miscommunicated or just plain wrong. Feel free to post comments on the blog.

Use the GIS app at your own risk.   Property ownership is displayed on the GIS app, the source being all counties in the state via the Wisconsin Statewide Parcel Map REST service.  When viewing property boundaries while hiking, please bear in mind the accuracy of this product is limited in some areas.  Also, the accuracy of the GPS on your smart phone may be limited as well.  Please do not trespass. This map does not give you permission to trespass, even if "X marks the spot".  Use common sense! Stay safe if exploring outcrops or other geologic features in dangerous areas such as along roadways.

Also, do not collect geologic samples without permission.  Most of the rock samples mapped here are special specimens known as "leaverites" .... in other words, "leave 'er right where you found it".
