When you visit many natural places, you need to keep track of them (or at least I do). Here is how I do that presently.
This spreadsheet is in the same Excel workbook as the previous one. If I visit a particular SNA, this spreadsheet takes note of which county that site is located in and updates the county visit statistics accordingly. Fun fact: Wisconsin has 72 counties, but 2 (Menominee and Kewaunee) do not have SNA’s. The entirety of Menominee County is an Native American reservation, but Kewanuee is just lonely I guess; it borders Door County and its 28 SNA’s to the north. Also, South Branch Beech Grove SNA (Oneida County) and Two Creeks Buried Forest (Manitowoc County) directly border Menominee and Kewaunee Counties, respectively.
