The Mount Washington Observatory put together this video of the snow retreating on Tuckerman Ravine this month. It was created using the still images displayed in the Tucks Zoom view of their Premium Content webcam views. The video covers images from May 1 to May 12.
Not sure what’s cooler, watching the snow disappear from the ravine or early on seeing the line of skiers looking like ants stretching from the top of the ravine to the bottom.
