An estimated 1,500 visitors a day hike across the lava flow fields to view the ocean entry and search for active lava breakouts. Round-trip walking distance is far; a one-way trip to the ocean entry from Kalapana is around 4 miles. Add the chase for active lava, milling about, and your hike will quickly add up to more than 10 miles when you return.

This week, we visit the observatory that monitors a volcano that produced some of the largest eruptions known on Earth — Yellowstone!
