Working as a
prospector, Brigham followed the
Mississippi River by horseback and stayed at
Galena in 1822. One of the earliest visitors to the area, he helped miner James Johnson build one of two log cabins at the camp. Returning to
Springfield, Illinois, he left there with a team of oxen heading for the
lead mines region of southwest Wisconsin to build his own mining camp. He was originally part of a mining party which lived along the
Platte River, only four miles from present-day
Platteville, Wisconsin. However, the party soon left the area under threat from the local
Winnebagos during the
Winnebago War. In the spring of 1828, Brigham arrived in
Dane County, Wisconsin to work the lead mines in and around
Blue Mounds. Using such crude tools as a
windlass,
rope and
tub, over 4,000,000 lbs. was taken from the mine and hauled by wagon to Green Bay, Chicago and Galena, in total a 15-day trip. He later accompanied
William S. Hamilton and
Henry Gratiot and several others to Green Bay to negotiate boundaries between the miners and local tribes. By 1828, he had established a successful lead mine operation at
Blue Mounds, as well as operating an inn and general store serving the local miners, local tribes and other travelers. His tavern became a popular stopover along the
Old Military Trail, and soon his small mining camp grew with settlers arriving from
Illinois and within the
Michigan Territory. He was honored by the Michigan territorial governor
Lewis Cass and appointed a
magistrate. He held the position of magistrate for four years, serving as
justice of the peace, and from the winter of 1830–1831 until 1837, as
postmaster of
Moundville. and a state representative in 1848, == Death ==
