PHOENIX — Grand Canyon National Park has been recognized for its work in reducing light pollution of the night sky.

The Arizona Republic reported Wednesday that the International Dark-Sky Association has named the Grand Canyon an International Dark Sky Park.

The park and the Grand Canyon Conservancy started retrofitting more than 1,500 light fixtures after it was given provisional dark-sky status in June 2016.

Workers put in lower-wattage LED bulbs and shields to focus the light on the ground.

The park says 67% of its lighting complies with association guidelines.

The park and conservancy aim to have 90% of the lighting meet standards by 2022.
