Tucked away in the Fishlake National Forest, Pando might look like any other grove of trees, but it’s actually a unique organism, and well-known around the world. It’s thought to be the heaviest living thing on the planet, and one of the oldest as well.

Pando is clustered over 140 acres in the Fishlake National Forest. You'll find it nestled in the foothills of the Fremont River Ranger District.
