I think that you are talking about the old Itasca Grain Co. elevator dock. It was owned by Cargill in the 1960's and I think that the last owner was Bunge. The elevator was torn down and the dock is called the Power Squadron Dock today. It is used for Duluth Power Squadron events and private boat owners almost every day. Hope that this answers your question.

There were two docks located East of BN #5. One was a coal unloading dock, the Northwestern Hanna Fuel (Old Hanna Dock). Also there was a grain elevator Canadian ships often loaded at. Both docks were affiliated with Hanna. From the 1961 Ship Masters Directory. Mike
