As the city's name suggests, its geography is dominated by a high ridge separating the valleys of theBig andLittle Cottonwood Creeks. At the eastern edge of the city, these valleys narrow into theBig andLittle Cottonwood Canyons within theWasatch Mountains, respectively. This is reflected by the city's official nickname, "City between the canyons". The ridge is covered in suburban housing, but most commercial development has been restricted to the lower-lying areas north of the ridge (along Fort Union Boulevard, inFort Union itself, and near Big Cottonwood Creek and the "Old Mill" in the northeast corner of the city).
State Route 190 andState Route 210 run near the eastern edge of the city and provide access to the canyons; they are the only state routes that enter the city.Interstate 215 runs along the northern border of the city, andState Route 152 touches the city at a point. The city is building amulti-use trail along the full length of Big Cottonwood Creek within its borders.
