Lighthouse Fresnel Lens
Owl’s Head lighthouse, Rockland, Maine. Once a year I’m told, the lighthouse is open for tourists to climb the tower. It’s not much height to the top. But it is fun to see the light up close. This is the one and only time all year. I didn’t plan to be there but I was happy to climb up. The sunlight shining through was warm enough for me to imagine how much heat there must be when this light is in action.
