The Monticello Community Historical Society organized that same year and incorporated 11 years later. The Society operated the Monticello Historical Station and Museum in the hall which was built to house the township fire station in 1974. The museum closed in 2025, but the historical society continues to host programs at the Monticello United Methodist Church.

The Monticello Community Historical Society organized the Historic Monticello Driving and Biking Tour of interesting sites from the former township.

It was from the driving and biking tour that we learned that Wild Bill Hickok Park in what is now Lenexa occupies a small portion of the land which Hickok claimed in 1857. Hickok was elected as one of the 4 constables of Monticello Township at the age of 20 on March 22, 1858. He also served in the Free-State Army and his cabin was burned by pro-slavery men in late 1858. He abandoned his claim and left Johnson County in 1859.
