Chief Colorow Ignacio Ouray Walkara, also known as Wakara or Walker, was born about 1808, along the Spanish Fork River in what is now Utah, one of five sons of a chief of the Timpanogo band. Described as being over six feet tall and extremely strong, he was a successful warrior from a young age. His piercing eyes earned him the nickname "Hawk of the Mountains."

As a young man, the Spanish did everything they could to keep the Indians in check by promoting raids and violence between the tribes.  

With language skills that included Spanish, English and several native tongues, he became a skilled negotiator. Also known for his excellent marksmanship, discipline, and bravery, he quickly became a leader, gathering a raiding band of warriors from the Great Basin tribes, including Utes, Paiute and Shoshone. Attacking ranches and travelers along the Old Spanish Trail between New Mexico and California, other tribes feared his reputation to such an extent that they paid him tribute in return for protection and assistance.

Often wearing yellow face paint, he became known as a great horse thief, stealing some 3,000 horses in southern California in the 1840’s. Mountain men, James Beckwourthand Thomas "Pegleg" Smith were known to trade with Walkara, providing the band with whiskey in return for horses.

In 1845 Justice of the Peace and assistant for Indian Affairs in Riverside County, California, Benjamin Davis Wilson, ordered that Walkara and his marauders be tracked down and brought to justice, but he had no success.

By the time that the Mormons began to settle central Utah, Walkara had become the chief of his Ute band who were, at first, helpful and cooperative with the Mormons.

However, when the Mormons began to attempt to suppress New Mexican trade, tensions developed with the Ute, who had long depended on the trade, especially that of native slaves, to which the Mormons strongly objected. Though Brigham Young had negotiated a trading relationship with Chief Walkara in 1850, the colonists began to interfere in many of the Ute transactions. At the same time, the area was being traveled more and more with non-Mormon trading expeditions and settlers and in a few isolated instances, some Ute Indians were killed. These tensions soon led to the Walker War, where Walkara led a number of Ute raids against the Mormon outposts.
