Two large waterfalls on the Yellowstone River mark its drop from the Hayden Valley into Yellowstone Canyon — the Upper Falls and the — wait for it — Lower Falls. This is the taller of the two, Lower Falls — the river drops 308 feet (94 m). The “yellow stone” that gave the Lake, the River and the Park its name is visible. Also, especially if you click for the larger version, you can see tourists that were willing to make the hike down to the brink — I’ve been, but not this time. It’s a long trek back up.
