We previously did an article on the 2024 solar eclipse for the Washington 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 Washington in regards to light pollution and astronomy.
|Number Of State Parks||140|
|Number of Different Bortle Scales||7|
|Level 1 Bortle Scale State Parks||0|
|Level 2 Bortle Scale State Parks||9|
|Level 3 Bortle Scale State Parks||24|
|Level 4 Bortle Scale State Parks||46|
|Level 5 Bortle Scale State Parks||41|
|Level 6 Bortle Scale State Parks||10|
|Level 7 Bortle Scale State Parks||5|
|Level 8-9 Bortle Scale State Parks||5|
Here is a show of the colors of the markers, to know how to read the map.
