History.
The earliest French colonial families had long-established family sugar camps (les sucreries) along the creek to process sugar. In 1797 the younger son of Pierre de Lassus, Commandant of New Bourbon received a grant by the Spanish government to establish a sugar mill along the creek. Over time the area around River aux Vases became known as a breeding center for mules. Mining was also prominent in the area and River aux Vases sandstone was used in the abutments of Eads Bridge in downtown St. Louis, with decorative onyx and limestone quarried nearby.
