Abu Oreum

This guide to Abu Oreum walks the numbers that don't add up: a crater sunk fifty-one meters into a hill, yet dropping seventy-eight meters below its rim. It traces the volcanic burst that carved it, the more than 360 other oreum scattered across Jeju's slopes, and how this one earned its name from the nearby village of Songdang and its eighteen thousand guardian deities. Along the ridge trail, listen for how the local name drifted from front to father over time.
