November 23, 1833
William Austin Burt was appointed U.S. deputy surveyor.
During the 1830s and 1840s, Burt and his crew surveyed much of Michigan. Burt also invented the solar compass to work in areas where minerals in the ground might make the needles of their magnetic compasses act wildly and produce errors. Burt’s solar compass saved the U.S. government lots of money when the country’s western territories were surveyed.
