About Mariposa County

The Mariposa area was said to have been named by a Spanish Priest under the direction of explorer, Gabriel Moraga. Moraga was the leader of a 25-man troop that explored central California in 1806. When he and his expedition came upon a creek laced with thousands of yellow butterflies, they named the area “Mariposa” which was the Spanish word for butterfly.
