John Sivers, an early pioneer of this community, arrived at Coonville (Glenwood) from England on July 4, 1849. He operated the first grist mill built on this site by J.W. Coolidge in 1849, established the Sivers-Deupree Mill on Keg Creek north of Glenwood in 1865, and operated the Vinton Mill at Old Pacific. This park is part of the original Sivers Homestead.
