Searching for a clear window into the cosmos near Jamestown, ND? While enthusiasts often gather at local vantage points for its accessibility, scientific audits conducted by the National Park Service at Buck Hill provide the most accurate reading of the regional sky quality, measuring at a Bortle 4.0. Atmospheric stability in the Jamestown region is often influenced by local topography, which can help settle the air for high-magnification viewing.

The Best Times for Stargazing in Jamestown

For the best results in Jamestown, aim for a ‘New Moon’ window. In these dark-sky conditions, the absence of moonlight allows the Milky Way to cast visible shadows.

Expert Tips for Jamestown Observers

Before heading out to local vantage points, we recommend arriving during civil twilight to scout the terrain safely. For the best views at this spot, try to observe targets when they are highest in the sky to minimize atmospheric interference. Local enthusiasts often frequent this spot, making it a great place to meet experienced observers. Regardless of your gear, allow 30 minutes for your eyes to fully dark-adapt.

Buck Hill

Theodore Roosevelt NP

21.36 SQM
Bortle Class 4

"Fairly clear night at this ideal monitoring site in the SE portion of the south unit of the Park. Direct glare lights visible immediately to the east of the park boundary in the form of oil drilling rigs and gas flaring. The more distant lights from the engergy development to the north of the park are still easily visible from this location. The light dome of Dickinson is also easily visible to the east. The nearby town of Medora can be seen, but is not too bright for its size. The Milky Way is easily seen, though its reach towards to the northern horizon is stopped well short by lightglow."

"Extensive lights and gas flares along horizon from NW to SSE. One installation at approximately 30° is very close and causes loss of night vision. Sky to the southwest not showing stars below 15° (might be clouds or haze). Almost entire perimeter of South Unit has some level of lights. Zenith is still relatively dark after sufficient adaptation. Shortly after sunset, thick haze layer from gas flares is very visible along north and ast horizon."
