the pier at grand marais michigan

the pier at grand marais michigan is built to withstand the destructive forces of the great gitcheegumee (lake superior). we all know about its fury and power, if not first hand, at least from mr. lightfoot's lyrics. it can be pretty crazy.

well, the pier--actually a sea wall protecting the entry to the harbor--has some sections built out of interlocking steel sections that are filled with rock and cement.

 we wandered out on this structure last week and i found a bunch of interesting perspectives i wanted to capture. first, i was intrigued by the metal outer shells of the structure. their lego-like interlocking fingers were very cool, so they are the "interlocks." later, i found some rocks that still had the holes in them that were used to mine them from wherever they were quarried, and that set was dubbed the "rockholes."
