Chris Skoglund, of Mark’s Window Cleaning, Inc. of Iron Mountain, cleans the gigantic Cornish Pumping Engine in the museum located at 300 Kent St. in Iron Mountain. The massive 54-feet tall engine, including a distance of 75 feet from the back of the flywheel, which has a diameter of 40 feet, to the end of the pump bob and the surrounding concrete floor were all degreased and power washed. The project was completed by Skoglund in four and a half days, compared to the estimated time of 10 days work. Mark’s Window Cleaning, owned by Mark Couillard, charged $300 less than usual as a donation to the museum. The Cornish Pumping Engine is the largest steam-driven pumping engine ever built in the United States and is listed on both the National Register and the State of Michigan Register of Historic Sites.
