We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
I reviewed some copies of lighthouse construction blueprints a long time ago. It appeared that the submerged sections were carved of stone sections. These were stacked on undersea rock. The last block was laid at high tide. I have no idea how the masonry sections rose above that. They must have started with calm seas at low tide.
My father was in the Coast Guard in the mid-fifties. He and my mother lived in Alaska and many times he would tell us the harrowing stories of getting out to the lighthouses when it was his time for duty. This video brings his words to life for me, however I believe for the most part they used small boats from the cutters to the lighthouse in very rough seas. He may have enjoyed this much more. After all people now pay to zip line through the air.
Global warming (even if you concede all the alarmism) is generally irrelevant to coastline shifts. They have been eroding and shifting literally forever, and will continue to do so. Lighthouses that were well inland many years ago are now on peninsulas or islands; lights that were in the middle of river channels are now in muddy trickles of water well on their way to becoming swamps then proper land. Artificially straightened rivers revert to their oxbow shapes at the first signs of flooding, and flood control measures are often inadequate to hold back actual floods once they decide that, by God, it's time to put some land and people underwater.
Only in the last 20 years or so have civil engineers really started to understand some of the ways in which water resists doing what we tell it to do. It has begun influencing how they treat coastlines and the areas near them. It isn't the usual misguided nature worship of the eco wienies; rather it's an acceptance of the fact well known to sailors, that the water is going to do what it feels like doing and it doesn't care much - or need to care much - about your objections to that. Masses of water are impersonal and uncaring destroyers of all that gets in their way. Perhaps that relates to some of the the symbolism tied up in Noah's flood.
