NASA Landsat Images Capture Pine Creek Gorge’s Autumn Splendor

NASA’s Earth Observatory released two Landsat 8 OLI images of Pine Creek Gorge, the “Grand Canyon of Pennsylvania,” taken on October 9 and 25, 2026. The photographs show the gorge’s 45‑mile stretch of forested cliffs turning from green to vivid reds and golds as deciduous trees shed leaves. The canyon, carved by glacial meltwater during the last ice age, now hosts a mixed hardwood and oak forest that has recovered from extensive 19th‑century logging. The images, part of NASA’s ongoing monitoring of Earth’s land surfaces, provide a clear record of seasonal color change and help illustrate the canyon’s ecological recovery. Visitors can view the gorge from state parks and the Pine Creek Rail Trail, and the area is protected as a National Natural Landmark.
