Shedding some light on the colorful limestone overhang

with 34 comments

Last week you heard about and saw two pictures of a limestone overhang in a hard-to-reach section of Great Hills Park. I mentioned that direct sunlight never reaches the overhang’s wall and ceiling. That said, the floor of the overhang is a creek bed; with enough water in it, and with the sun low enough in the sky, some rays of light bounce off the water and onto the ceiling of the overhang. Because the water’s surface isn’t perfectly still, the reflected light shimmers overhead, as you see in today’s picture from June 10th.

And here’s a clever quotation for today: “If somebody thinks I’m cherry-picking, show me the other part of the tree.” — Steven E. Koonin in a televised interview about his book Unsettled on May 25, 2021. Also unsettled is the question of why English speakers have picked cherry-pick rather than the alliterative peach-pick or plum-pick, or else apple-pick, lemon-pick, or some-other-fruit-pick. Maybe cherries got picked because they’re small, and therefore cherry-picking is like nit-picking. One thing’s for sure: cherries make for a much tastier pie than nits. And did you know that cherries was originally the singular of the word? We got it from Anglo-Norman cherise. But that sounded to the folks in merry old England like it was a plural, along the lines of berries and ferries, so they created a new singular, cherry. Linguists call that process back-formation, for which today’s picture of the geological formations at the back of the overhang is therefore appropriate. What fun to lead you from limestone to linguistic information and back again.
