I've never heard of Harry A. Colt...probably a misprint.
Colt designed the original CC of Detroit which was on or near Lake St. Claire. It hosted the 1915 US Am. Alison built a new course in 1927 at a new site.
RTJ completely redesigned the course prior to the US Am in the 50's. I believe RTJ II remodelled it again more recently. I'm certain Rich applauded both moves.
In the region Alison designed/redsigned CC of Detroit, Plum Hollow, York Downs, St. Georges, Kirtland, Columbus, Lochmoor, Westwood, Orchard Lake, Lost Nation and Colony.
Colony is feature Daniel Wexler's fine book Lost Links.
