Biohazard Cleanup Near Downtown Monroe Monroe, UT

Monroe is a city in Sevier County, Utah, nicknamed "The Little Green Valley" for the irrigated fields around it, with 2,515 residents counted in the 2020 census.

The 2020 census counted 854 households in Monroe, with a median age of 37.8 years.

In the summer of 1863, George A. Smith sent George Washington Bean to explore the Sevier River valley, and a small community named Fort Alma was founded on the east side of the river.

Indian hostilities during the Black Hawk War drove the original settlers from Alma in 1866, and by 1871 Moses Gifford, Walter Jones, Andrew Rassmussen, and others reclaimed the abandoned fort, planted crops, and built homes.

The community was renamed Monroe for the fifth president of the United States, James Monroe, when its post office was established.

Monroe is home to naturally occurring hot springs with travertine deposits, produced by the Monroe-Red Hill geothermal system along the Sevier fault.

On the east side of town, hot water surfaces at 168 degrees Fahrenheit at about 200 gallons per minute, building the Monroe Mound, a travertine deposit about one mile across.

About a mile north of town, Red Hill Hot Springs also surfaces at 168 degrees Fahrenheit at about 100 gallons per minute, forming a deep red mound about one-third of a mile across.

Mystic Hot Springs, homesteaded in 1886 by the Cooper family and long known as Monroe Hot Springs, was renamed in 1995 and has operated under its current name since 1996, with soaking pools and vintage bathtubs set into a hillside.

Monroe sits at the foot of Monroe Mountain in the Fishlake National Forest, where Monroe Peak rises to 11,227 feet, the highest point on the Sevier Plateau, and the Paiute ATV Trail crosses the mountain.
