Summit County Utah
Summit County administrative offices are located at 60 North Main Street, Coalville, UT 84017; phone: 435-336-3200.
Summit County was first traversed by Mormon immigrants as early as the 1840s. The first white settler in the area that would become Summit County came in 1853. His name was Samuel Comstock Snyder [1808-1866]. The county was organized in 1854. Snyder built a saw mill and a grist mill and created a reservoir by harnessing the flows of White Pine, Red Pine and Willow Creeks.
