Oregon State Parks Light Pollution Map

Oregon State Park

We previously did an article on the 2024 solar eclipse for the US 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 Oregon in regards to light pollution and astronomy.

ItemHow ManyPercent

Level 7 Bortle Scale State Parks21%
Level 8-9 Bortle Scale State Parks42%
Table 1: State Park Info

Some of the 200 state parks weren’t included because they were trailheads or other options such as waysides that weren’t appropriate to add in for potential astronomy.

Here is a show of the colors of the markers, to know how to read the map.
