LEÓN, Nicaragua: a tourist who set off down Cerro Negro on a plywood sled last March never reached the bottom, according to the guide who watched him push off from the summit. His dust cloud arrived at the base on schedule. He did not.

He was last seen about two-thirds of the way down in the standard yellow jumpsuit and a paisley bandana, both hands on the rope, leaning back exactly as the safety briefing instructs.

The sled was found at the bottom, upright and still warm.

Since then the story has become something León tells. Guides call him El Amarillo, a figure in yellow who appears on the slope near sunset, always mid-descent and never any closer. Some say he hit a pocket of hot gravel and slid into the mountain. Others say the volcano kept him because he was the only one who followed the briefing. A woman who sells water at the trailhead says he simply liked it too much to stop, and that on windy evenings she hears a long hiss of gravel coming down the slope with nobody on it.

Sightings are difficult to verify, since every boarder on the mountain wears the same yellow jumpsuit.

Tour operators have adapted. Groups now count off at the summit and again at the base, and the safety briefing has a new final instruction: if a man in yellow passes you on the way down, let him go.
