Holyoke in Phillips County, Colorado — The American Mountains (Southwest)
Welcome to Colorado
Colorado's vast plains, rugged mountains, and grand plateaus, so magnificent in their beauty and variety, seem at time to overshadow the state's history and people. But look closely. The story of Colorado is every bit as dramatic as the physical terrain. Many peoples have helped sculpt Colorados past: the ancestral Puebloan peoples, whose civilization dates back thousands of years; the Utes, who occupied the Rockies for perhaps a thousand years and more; the numerous other native peoples who lived in this region; Hispano pioneers, the states first permanent non-Indian settlers; and the men and women who came here and built cities, dug mines, and planted farms! Colorado's natural endowment is world-renowned. But the state's history, like the land on which it unfolds, features its own breathtaking peaks and valleys, its own scenes of improbable awe and splendor.
A new generation of roadside markers is in place to help you experience the history of Colorado in all its color and fullness. Produced by the Colorado Historical Society, the Colorado Department of Transportation and the Federal Highway Administration in collaboration with thousands of local partners, these illustrated signs introduce you to people and events as large and colorful as the state itself. Every mile you travel in Colorado has stories to tell; the markers help you chart your journey through the past.

Excerpt: On April 30, 1598, during Juan de Oρates expedition north from Mexico up the Rio Grande del Norte, he claimed all of that rivers drainage for Spain. The Adams-Oρis Treaty of 1819 between Spain and the United States more precisely defined, Spanish Territory in present day Colorado as everything south of the Arkansas River and west of a line running due north from the Arkansas River Headwaters on Fremont Pass up to the 102nd parallel.(Submitted on December 3, 2025, by Cosmos Mariner of Cape Canaveral, Florida.)
Juan de Archuleta led a Spanish excursion into what in now Colorado in 1664. The first traceable Spanish expedition into Colorado came in 1694 when Diego de Vargas, the governor of New Mexico, followed the Rio Grande to a tributary, Culebra Creek. In 1706, Juan de Ulibarrν and forty soldiers traveled north to the Arkansas River, skirting the Spanish Peaks. Antonio de Valverde, governor of New Mexico, became the next known official visitor in 1719. Juan Maria de Rivera became the first recorded explorer of southwestern Colorado in 1765. In 1779 New Mexico Governor Juan Bautista de Anza led 645 men on the last major Spanish thrust into Colorado.
Other Spanish and Mexican expeditions have gone unrecorded in a state that Hispanics were the first Europeans to explore, map, write about and settle. As the first and the largest group on non-natives to settle Colorado, their story is essential to the history of the state.
