Located 16 miles (26 km) up the Weber River from Ogden, Mountain Green is the world headquarters of the Browning Arms Company.

[3] Mountain Green lies in Morgan Valley at the east end of lower Weber Canyon, just north of I-84 at the interchange with Utah State Route 167 (Trappers Loop).

The next day, 25 American Rocky Mountain Fur Company trappers belonging to John Henry Weber's brigade arrived under the command of Johnson Gardner.

On May 24, 1825 John Gray, a half-Iroquois leader of the freemen trappers who were dissatisfied with the conditions and pay under the Hudson's Bay Company, declared their intention to leave Ogden's brigade.

The deserting HBC freemen joined the American trappers on their way to Henrys Fork (Green River) about 120 miles to the east for the first of what was to be sixteen Rocky Mountain Rendezvous, organized by fur trade entrepreneur William H. Ashley, which took place on July 1, 1825.

When Mormon pioneers began to arrive in Morgan County in the 1850s, they found a man named Ben Simon already in possession of the land in the Mountain Green area.

Such early settlers as George W. Higley and Gordon Beckstead moved to Mountain Green in the 1850s with permission from the Simons and the Native Americans.

They purchased a Mountain Green farm in 1961, and by 1968 Browning had relocated its executive offices, research and development, sales and data processing to the Morgan County location.

In 2007 the northern Utah section of the American Institute of Architects offered a design assistance team to develop guidelines for a new Mountain Green town center.
