Lake Shetek State Park was established in 1937. Located near the entrance to the park is the Lake Shetek Monument, a stone memorial pillar which marks the mass grave of 15 settlers who were killed during the U.S.-Dakota War in 1862.

The site for the stone monument was selected by William Duley Sr., who lost two of his children during the US-Dakota War. The monument was dedicated in 1925.

Inscription on monument:

"At this site lie the bodies of fifteen people in a mass grave ten feet long, four feet wide and four feet deep. Contained in this grave are the remains of six adults and nine children killed either at Lake Shetek or at Slaughter Slough on August 20, 1862. The fifteenth victim, whose name does not appear on the Monument, was a twelve year-old boy killed in the late afternoon of the 20th. Mistakenly identified as Frank Eastlick, he lies with the rest, his name unknown to this day. Originally, the bodies of the slain lay unburied from August 20, to October 16, 1862. The bones were collected and buried by the edge of Slaughter Slough in a shallow grave and lay there until the following year. On October 31, 1863, a military burial party, commanded by Captain Starkey and assisted by Wm. Duley, Captain of Scouts, with the aid of Thomas Ireland, Charles Hatch and H. Watson Smith reburied the remains at this present location. The State of Minnesota began construction of this monument in 1924. It was completed and dedicated in 1925."
