Of note, William Fletcher and Anne Hawley Reynolds in 1852 brought Ellis Reynolds Shipp to live, which Shipp became the legendary MD, Obstetrician, and Pediatrician, through the young women's midwife training program of Dr. Richards and Eliza Snow, beginning her training in young women's MIA in Pleasant Grove.

[6] Pleasant Grove was officially incorporated as a town January 18, 1855, by which time the settlement had grown to 623 people.

The southwest monument would have been located near 300 South 100 West, the area is now occupied by a large parking lot and retail store.

Portions of the 1994 television series The Stand, adapted from the Stephen King novel, were filmed in Pleasant Grove.

According to the United States Census Bureau, the city has a total area of 9.2 square miles (23.7 km2), all land.

The city council is made up of five members: Dianna Anderson, Eric Jensen, Todd N. Williams, Cyd LeMone and Brent Bullock.

The first annual “Strawberry Day” (initially a single-day event) was held on June 21, 1922, with 10,000-15,000 people in attendance.

[17] The festival retains the traditional name, even though large-scale commercial growing of the fruit no longer occurs in the city.
