As we previously did articles on the 2024 solar eclipse for the several state parks, and figure that there is an amazing opportunity for mapping those state parks to their Bortle Scale values. With the help of https://www.lightpollutionmap.info, we created the following table to provide information about the entire state parks for Minnesota in regards to light pollution and astronomy.

Item	How Many
Number Of State Parks	72
Number of Different Bortle Scales	8
Level 1 Bortle Scale State Parks	1
Level 2 Bortle Scale State Parks	11
Level 3 Bortle Scale State Parks	16
Level 4 Bortle Scale State Parks	22
Level 5 Bortle Scale State Parks	16
Level 6 Bortle Scale State Parks	4
Level 7 Bortle Scale State Parks	0
Level 8 Bortle Scale State Parks	2
