If you’re looking to escape the light pollution of Jasper, you’re in luck. While enthusiasts often gather at Wahnsiedler Observatory for its accessibility, scientific audits conducted by the National Park Service at Houchin’s Field provide the most accurate reading of the regional sky quality, measuring at a Bortle 4.0. The transition between the urban infrastructure of Jasper and the more rural stretches of IN creates several ‘dark sky’ corridors.

Mammoth Cave NP
"A very calm, humid and clear night. Dewfall occurred during data collection, however dew heater prevented lens fog. Multiple light domes evident from site, as well as a continuous glow along horizon in all directions. Airglow was present. Andromeda galaxy easily visible, Beehive (Pegasus) visible with medium effort. Prominent dust lanes in Milky Way visible at zenith, but not below ~50 degrees. Limiting magnitude found in Pegasus."

Fort Donelson NB
"SQM of 20.47 at 2035 local time. Only fair transparency and seeing. Some fast moving clouds. High humidity. Milky Way visible from 20 degrees above north horizon. Great rift visible, Saggitarius cloud not easily visible, Scutum cloud not visible. Milky Way about 10-12 degrees wide, but faint and no fine details. To the NW a blue white light dome easily seen. Due East is the Clarksville lightdome almost 25 degrees high and 15 degrees wide. Core is bright. Adjacent to the light dome is a spotlight (which we determined was coming from the cemetary here in FODO park). To the West and Southwest is another lightdome fainter than Clarksville, but brighter than the Milky Way"
