Last worked about 50 years ago, sulfur was mined throughout this valley. Below is the old road south of San Felipe.

Many pits and caves were dug. Perhaps more to escape the sun than for the yellow mineral.

Sulfur is used to make many products including gunpowder, matches, and fertilizer. When lit with a match, this mineral burns and gives off a poisonous gas (sulfur dioxide).

The girls became good Baja amigas.
