Darkest States 2024

The Bortle scale serves as a valuable tool for measuring the darkness of the night sky, providing insight into optimal stargazing locations across the United States. Ranging from Class 1 (minimal light pollution) to Class 9 (severe light pollution), the scale offers astronomers and enthusiasts a standardized method for assessing the quality of celestial observation sites.

States such as Alaska, California, and Oregon boast some of the darkest skies in the country, with Bortle scale ratings ranging from 7 to 13. These regions offer unparalleled opportunities for stargazing, with designated sites like Anza-Borrego Desert State Park, Death Valley National Park, and Prineville Reservoir State Park providing pristine views of the cosmos.

Furthermore, the International Dark-Sky Association (IDA) plays a crucial role in preserving and promoting dark-sky sites worldwide. Certified locations, including national parks, state forests, and wildlife reserves, offer protected environments for observing the wonders of the night sky.

Local astronomy clubs serve as invaluable resources for enthusiasts seeking precise, local-scale guidance in locating the darkest and most ideal viewing locations. By collaborating with these organizations and utilizing resources such as the IDA's Dark Sky Finder, individuals can embark on unforgettable journeys to explore the beauty of the cosmos from some of the darkest states in the nation.
