Humble Beginnings
John Williams Gunnison was born on November 11, 1812 in Goshen, New Hampshire. At the age of 18 he traveled to Hopkinton Academy, where after one term, he went on to teach at the local school. During his years as a teacher, he prepared himself to enter West Point Military Academy. In June of 1837 he graduated second out of fifty .
Gunnison began military service later that year when he was ordered into active duty under General Zachary Taylor. Violent battles had been brewing in Florida between the Seminole Indians and white settlers. As peace talks were undertaken, Gunnison was ordered to explore unfamiliar lakes and rivers in search of provision routes south to Fort Besinger. Although the assignments were challenging and there were many opportunities for adventure, the heat and humidity of the South took a toll on Gunnison’s health. In 1838 he received a transfer to the Corps of Topographical Engineers.
Gunnison experienced many things in his new job and personal life. Among them was his marriage to Martha A. Delony on April 15, 1841 and the births of their children in the years to follow. In the summer of 1841 he received his first western assignment to do a standard survey of the unexplored, wild country of the Wisconsin-Michigan border. Through many challenges and hardships, one of which was long periods of time away from his family, Gunnison and the survey crew persisted and eventually mapped much of the border land and the shores of Lake Michigan.
Going West to the Utah Territory
Gunnison’s first sight of the western lands came as a member of the Captain Stansbury Utah Territory Expedition of 1849. Gunnison, having caught the exploration bug during his previous expeditions in Florida and Michigan, was thrilled to embark on this new adventure. Their task was to explore the route to the Mormon community in Utah.
After a long, yet beautiful journey through the Great Plains and southern Wyoming, they arrived in the valley of the Great Salt Lake. They explored and mapped the Great Salt Lake region and gathered scientific information about their surroundings. That winter incredible amounts of snow fell bringing with it many dangers and hardships. Communication was cut off, leaving the crew with many idle hours. Gunnison began to study the Mormon Church and wrote a book titled The Mormons, or Latter Day Saints in the Valley of the Great Salt Lake: A History of their Rise and Progress, Peculiar Doctrines, Present Condition.
That same winter there was an uprising between American Indians and the Mormons near Salt Lake City. Gunnison negotiated between the two parties, winning the admiration of his peers. The experience led him to believe he could be a mediator, a belief that would later prove fatal.
