The Fall Line

I have a mild case of fatal familial obsessive-compulsive disorder. (At least, if that were real I’d have it.) Today’s obsession is the Fall Line. It’s the line that runs through the big east coast cities — New York City, Trenton, Philadelphia, Wilmington, Baltimore, Washington D.C., Richmond, all the way down to Columbia SC and […]

Guest Post: Cuba’s Stories in Stone

Starting about 135 million years ago, long after the Pangea supercontinent fragmented into shards of planetary crust, one of those geological slivers began noodling toward the north and east. Near the end of the Eocene epoch, it bumped into what is now Florida. With a newborn ocean giving it a shove from behind, it overrode […]

A stark introduction to geologic time

When I was a kid, my mom would measure time for me in units of Sesame Street. During a road trip when I’d inevitably ask, “Are we there yet?” she might answer, we’ll be there in two Sesame Streets. For a kid, two hours can seem like forever. We imagine the world through the lens of […]

Dance Party!

I miss dancing. One of my favorite activities as a kid was dropping the needle on our Hooked On Classics record and letting loose across the living room’s faded oriental rug. Later, I danced with gusto in church pageants, whether in charming second-grade square dances or hippie-esque liturgical dances that involved wearing leotards and waving […]

The Pursuit of Balance

My neighborhood, as I’ve mentioned, is an interesting place: At our weekly potlucks, we speculate on everything from the number and sex of the next batch of goat kids (money’s on two girls) to the efficacy of bourbon as mouthwash (not promising, sadly). Last week, a guest announced that he was on his way to a […]

Galápagos Monday: Southern Inhospitality

This is the second installment of a six-week series about my recent trip to the Galápagos. You can read my first post, about tortoises and donkeys, here. At dawn on June 6, more than 30 years after Lynn was chasing tortoises at the top of Alcedo, our boat anchored near the volcano’s base in Urbina Bay. By […]

Guest Post: Continuity and Deep Time

About a decade before my father died, he asked me to start collecting rocks for him. I didn’t fully understand why, but since I was studying geology at the time, I began to pick them up wherever I visited. Limestone from the Alps; granite from New Zealand. He kept the rocks I collected on a […]

Guest Post: Oldest Rocks Could Weigh A Man Down

“It’s not your usual rock that you would find,” says Jonathan O’Neil, a geologist at the Carnegie Institution in Washington DC. It’s a bit of an understatement because O’Neil is referring to what he believes is the world’s oldest rock, a funny-looking basalt embedded in the Nuvvuagittuq greenstone belt in northern Quebec. The rock itself […]
