In the meantime, her father, James Parker, was searching frantically for her. Rachel wrote that she had never seen open space the size of the Great Plains, and her travels with the Comanche took her to what her father later thought was Colorado in the northernmost part of the Comancheria. She attended a giant meeting of all divisions and bands of the Comanche, their allies the Kiowa and the Kiowa Apache, while the tribes considered whether to drive the Texans completely from the Comancheria, and conquer Mexico. There were thousands of Indians present, and Rachel Plummer wrote she had never seen so many people, nor imagined there to be so many Indians. Her accounts of her travels, and the untamed land she saw, remains one of the best descriptions of the early west in existence.
