Beautiful Sugarloaf Cove was saved for it. College students road trip to the North Shore from across the Midwest to see it. There's a great slab of it by the lower footbridge over the Temperance River. And I found it under glass in the Smithsonian. It's "pahoehoe," basalt hardened in the ropey form it had as it crept and cooled a billion years ago.
Most terms geologists use are either speaking German, Scottish, or Hawaiian. Hawaiian comes in handy on the North Shore because of all the volcanic features, which are found actually forming in Hawaii and as they were a billion years ago here. In addition to pahoehoe , we have aa (rhymes with baba). What's the difference? Pahoehoe was formed by fast-flowing lava, aa was from by the slow-moving stuff.
I think we could use some more Hawaiian language in our daily use:
"pupu"=snacks "kapu"=sacred or forbidden "ohana"=family
That would make the Slade family the ohana of kapu pupu.
