Two Harbors Trip - Fall 2011 - The Lens at Split Rock Lighthouse
Split Rock Lighthouse is one of my favorite spots in the world to visit and I usually visit at least once a year. One of the things I enjoy about this lighthouse is that it still houses the original 3rd bi-valve type fresnel lens, along with the original mecury float and clockworks. It is a beautiful piece of machinery and it has been well maintained.
To give you some perspective, if I were able to stand next to the lens, it would be as tall as I am.
