The Pasto people lived along the Carchi River in pre-Columbian times. At the northernmost point of the Inca Empire the Pasto were never fully conquered by the Incas.[3] The Carchi was known as the Angasmayo River by the Incas and the early Spanish colonists. A natural stone bridge at Rumichaca was the northernmost outpost of the Inca Empire.[4]
