Did a thorough check all around the park (in three areas), and I think we can safely say that any remnant of this course is now gone (and it should be removed from DGCR's active courses).
Flat course with mature trees and a lake view. Targets are 20" diameter metal hoops. One is used twice for a total of 9 holes. Tees marked with numbered wood timbers.
From US 30; west on D59 4 miles to a right on M54 (Rolf Ave), 2 miles to park. Follow M54 to Cottonwood Point boat ramp. Course plays around ramp area.
