In the 1970s growth was phenomenal in the suburbs of the Wasatch Front. Sandy was one of the fastest-growing cities in the country at that time.

It is a rugged and geographically diverse state at the convergence of three distinct geological regions: the Rocky Mountains, the Great Basin, and the Colorado Plateau. Utah covers an area of . It is one of the Four Corners states and is bordered by Idaho in the north, Wyoming in the north and east, by Colorado in the east, at a single point by New Mexico to the southeast, by Arizona in the south, and by Nevada in the west. Only three U.S. states (Utah, Colorado, and Wyoming) have exclusively latitude and longitude lines as boundaries. One of Utah's defining characteristics is the variety of its terrain. Running down the middle of the state's northern third is the Wasatch Range, which rises to heights of almost above sea level. Utah is home to world-renowned ski resorts made popular by light, fluffy snow and winter storms that regularly dump up to three feet of it overnight. In the state's northeastern section, running east to west, are the Uinta Mountains, which rise to heights
