The San Luis Valley is a region in south-central Colorado with a small portion overlapping into New Mexico. The Rio Grande with headwaters in the San Juan Mountains about seven miles east of Silverton, Colorado flows through the San Luis Valley and then south into New Mexico. It contains 6 counties and portions of 3 others. The San Luis Valley was ceded to the United States by Mexico following the Mexican–American War. Hispanic settlers began moving north and settling in the valley after the United States made a treaty with the Utes and established a fort. Prior to the Mexican war the Spanish and Mexican governments had reserved the valley to the Utes, their allies. During the 19th century Anglo settlers settled in the valley and engaged in mining, ranching, and irrigated agriculture. Today the valley has a diverse Anglo and Hispanic population.
