Marshall Severson from Anchorage, Alaska, recently posted a video documenting the changes to glaciers since 1989.
“The video distills 40 years of flying over the same glacier area and how things have changed,” he told General Aviation News staff.
The 1989 video was shot from his Piper Colt, while the 2021 video was shot with a Go Pro camera on his Cessna 172.
