During the Middle Jurassic, about 160 million years ago, a huge salty lake (Lake Todilto) formed in the Entrada desert of northern New Mexico. It was very similar to shallow salt lakes found today in the deserts of Africa, the Middle East and Australia. Mud on the bottom of Lake Todilto formed limestone, and when the lake dried out, a thick layer of gypsum was left behind.
