This web camera documents visibility conditions in Denali National Park & Preserve during the summer months as part of the NPS air quality monitoring program. The camera has been temporarily relocated to Wonder Lake while a new visitor center is being constructed at the former camera location. The webcam now runs on solar power.

Air quality in Denali is usually excellent, although small amounts of pollution are measured in the park each year. Contaminant concentrations in Denali show a strong seasonal pattern, with a peak in the late winter and spring. The peak coincides with intercontinental transport of pollutants primarily from industrial sources, and can be seen throughout interior Alaska. In the summer, it is not uncommon for smoke from naturally-occurring wildland fires to obscure the view, but the most common reason the Alaska Range cannot be seen from Wonder Lake is cloudy weather.
