Originally called Belmont Park, this site was renamed in 1938 in honor of Colonel Owen Summers, a former member of the Oregon Legislature. Summers was the commanding officer of the Second Oregon Volunteers Regiment in the Spanish-American War. He also introduced the bill which later created the Oregon National Guard.
In the southwest corner of this park there is a huge rock, which came from Kelly Butte. This rock holds a bas relief image of Colonel Summers on a bronze plaque.
