It is the second most important city of the province after Rio Gallegos, and the most populated of the Deseado Department. The city was founded on November 20, 1901 by Navy Lieutenant Exequiel Guttero, captain of the Guardia Nacional, a ship that was transporting cables, equipment, and workers for the construction of a telegraph line south of Comodoro Rivadavia. The settlement was given the name of his wife Olivia (caleta means "small bay", "inlet"). The main economic activities around the city are petroleum, sheep and fishing.
