Miles Morris Goodyear (February 24, 1817 – November 12, 1849) was an American fur trader and mountain man who built and occupied Fort Buenaventura in what is now the city of Ogden, Utah. The fort was located approximately two miles south of the confluence of the Weber and Ogden rivers and about one-quarter mile west of the end of Ogden's modern 28th Street. Goodyear was the first recorded man of European descent to live in the Weber Valley of Utah.
Born in Hamden, Connecticut, Goodyear was orphaned at the age of four and served as an indentured servant for much of his youth. In Independence, Missouri, when he was nineteen, he joined the 1836 Whitman-Spaulding missionary party traveling west on the Oregon Trail. As described by his fellow travelers, the young Goodyear was "thin and spare," with "light flaxen hair, light blue eyes." In later years, Goodyear's hair was described as red. Goodyear left the party at Fort Hall, in modern southeastern Idaho.
For the next decade, Goodyear worked as an independent or "free" trapper, being unaffiliated with any of the major American or Canadian fur companies. He lived, for a time, with the Bannock Indians of southern Idaho. He traded in the Western mountains and visited various gatherings of mountain men and Indians, including the rendezvous of 1841. By 1839 he had married Pomona, daughter of the Ute Chief Pe-teet-neet. The couple had two children, William Miles and Mary Eliza.
Adapting to the progressive decline of the fur trade and the increase in emigrant traffic on the overland trails, Goodyear built a way station on a large westward bend of the Weber River. The enclosed fort, constructed with local cottonwood logs, was begun in 1845 and completed by the end of 1846. Four log cabins occupied the corners of the fort, with sheds, corrals, and a garden within the enclosure. Additional corrals outside the walls accommodated cattle, horses, goats, and sheep. Occupied by Goodyear and his family and a number of Indian helpers, as well as visiting trappers and emigrants, the fort served as a base for the rapidly diminishing fur trade in the Wasatch Mountains and as a meeting and trading post for overland emigrants.
