Autumn on the world's largest sponge

Moraine Creek in Rainstorm, Aerial View, Katmai National Preserve, Alaska

It was the squishiest place I had ever hiked. As I took a step, I felt the ground compress slightly, accompanied by a sound that was part hiss and gurgle. As I stepped again, the ground where I had been snapped back into place.

Walking on the lowland tundra of Katmai National Park and Preserve in Alaska is like walking on the world’s largest wet sponge. It’s a place where even when you can’t see water you can feel its impact.
