ROCK JAW - Key Persons
Paul Lindberg invented the first Rock Jaw to use while restoring the Round Island Lighthouse in the St. Mary's River which connects Lake Superior and Lake Huron. He used this first Rock Jaw to move and place over 1,500 rocks in 90 days. An experienced landscape contractor, Lindberg recognized that this invention was hugely superior to any other method he had used to date. He began manufacturing Rock Jaws for sale.
