Your blogger took these pictures of the Portland Head Light, in Casco Bay, from the Casco Bay Lines ferry in July, 2009. Wikipedia has a nice entry on the history and significance of the lighthouse (see here), constructed in the late 18th Century at the behest of George Washington. Moreover, the lighthouse itself maintains a webcam, to be found here. Click on the webcam photo to enlarge it.
Here is another photo of the same lighthouse, taken in July, 2011.
