About 30 adult men, some with their families and others with teenage sons, left Salt Lake City on Saturday, March 31, 1849, and arrived the next day at the Provo River near what is now Geneva Road and 200 North. Under the direction of Bishop John S. Higbee and his counselors, Isaac Higbee and Dimick Huntington, they began building Fort Utah on April 3. The 1.5-acre fort was built south of the Provo River and extended on both sides of what is now I-15. Its initial form consisted of two rows of eleven homes facing each other and forming the outside walls of the fort, and this enclosure was completed in six weeks. Families of the workers began arriving later in April, and surveyors divided land south and east of the fort into 55 five-acre plots, including one for the fort and one for a cemetery. By the fall of 1849, Fort Utah had become a thriving frontier community, but a year later the colonists began moving to a new, higher location at what is now North Park at 500 North and 500 West, where it became known as Fort Provo.
