Biohazard and Crime Scene Remediation in Mount Olive, AR

Mount Olive is an unincorporated community and census-designated place (CDP) in western Izard County, Arkansas — one of seven different Arkansas communities that share the Mount Olive name, and the only one the Census Bureau recognizes as a CDP in Izard County.

Mount Olive stands on the White River about 11.1 miles west-southwest of Melbourne, the Izard County seat, at an elevation of about 371 feet.

The Mount Olive area is among the oldest settled ground in Izard County: Jehoida Jeffery came to Arkansas in 1818 and settled on the White River near here, becoming one of the county's very first settlers and one of its first justices of the peace after statehood.

In the 1830s–1840s the Izard County seat was moved up the White River from Athens to Mount Olive, and the courthouse here was still standing in 1862, when it served as a Confederate enlistment post where Company G of the 27th Arkansas Infantry signed up; the seat later passed to Mount Vernon and then, in 1875, permanently to Melbourne.

Postal records show that a Mount Olive post office opened in 1847 and operated until 1960, and in the pioneer era mail was carried on horseback from Mount Olive some 160 miles to Thomasville, Missouri, over a route with only four post offices.

Mount Olive saw repeated Civil War violence: Union and Confederate cavalry skirmished and fought here in May and June of 1862, and on January 25, 1864, Union raiders came into town and burned it.

A state historical marker dedicated in 2015 at the Mount Olive Cumberland Presbyterian Church — Arkansas Civil War Sesquicentennial Commission Marker No. 80 — commemorates Mount Olive's Civil War history.

Mount Olive Township, one of Izard County's civil townships, takes its name from the community.

The Census Bureau first listed Mount Olive as a census-designated place in the 2020 census, which counted only 17 residents, making it one of the very smallest CDPs in Arkansas.
