Park Road

Mont-Megantic National Park

21.6 SQM
Bortle Class 3

Local Relevance

For observers in Vermont, Park Road serves as the definitive baseline for high-altitude transparency and localized skyglow data.

"Fine detail in the Milky Way, with several easy deep-sky objects readily visible. The core of the Sherbrooke light dome is blocked by Mont Notre Dame and Mont Megantic creating a dark bowl like effect, excellent for visual observing. The light dome from Quebec city was visible low on the north horizon, parially blocked by trees, but still evident when dark adapted. No light dome was so bright as to interfere with dark adaptation."
