Connectivity:
A remembrance of Michael Soulé

When one of the founders of conservation biology passed this week at 84, I heard it was peaceful, that he was ready. I imagine Michael Soulé’s heart and breath stopping and an incredible release of feathers and bones, colors of a million beetles, a rush of eyes of countless shapes.  You might say he ushered […]

Clovis and the Virus

Not long ago, a friend who lives nearby, a skilled hunter of arrowheads, found a beautiful fluted spear point. It came from between his house and mine, along a ditch. The find was stunning, what I think has to be Clovis technology from 13,000 years ago, its point as sharp as the day it was […]

Sunrise in the Caribbean

Wednesday night, Washington, D.C.: Because my work life is slightly on fire right now, and because I already spent 10 hours of this day either sitting in front of my computer or walking around in circles talking to people on the phone, I present to you a photograph of a sunrise in the Caribbean last […]

Alaska Calling

Arizona winter night, stars over pines, my buddy and I were heading for a hot tub on the outskirts of Flagstaff when a phone rang. It was a mutual friend, Jayme Dittmar, a dog musher on a 1,300-mile expedition by dog sled from Nome, Alaska, to the village of Utqiagvik on Point Barrow. She was […]

Guest Post: Weird Rock, Weirder Story

“There is an aspect to this story that is weirder than you can imagine.” That sentence was e-mailed to me by a geologist, Jan Kramers, at the University of Johannesburg in the waning days of 2017. I had e-mailed him about a paper of his in Geochimica et Cosmochmica Acta. The title of the paper […]

Technically, the Moon is a Boulder

This happened the other day not far from where I live. Boulders fall all the time around here, highways regularly blocked. This time, the wording is what stuck. The local sheriff’s post went viral when this fallen obstacle was described as a “large boulder the size of a small boulder.” With those words, this 10,000-pound […]

Rain on Other Worlds

I found this ill-cared-for painting from 1976, when I was nine, of a spaceship either taking off or landing on a barren world. This was before Star Wars, but I was well-steeped in forbidden worlds and Star Trek. I dreamed of alien planets, their skies red or green, their landscapes sere and wind-torn. I stared […]

Children Like Sand

This post originally ran October 30, 2017 Sand blowing and grains hurdling over each other, landing and knocking the next, is called saltation. This is how dunes move, not sheering chaos, but each grain effecting the other, billiard balls knocking each other down the line. Kids found that if they stood on a dune crest, […]
