Remembering Randy Udall

Late last month, 61-year-old Randy Udall shouldered a backpack and set out, alone, into the Wind River Mountains of Wyoming. It was a habit of his: Randy was an experienced outdoorsman, and he periodically retreated from his busy, public life into the solitude of the Wind Rivers. He told his family that he would be […]

Returning to my roots

Earlier this week, I had the privilege of spending a few days at a place that nurtured my interest in science. The Mountain Research Station was where I conducted my first independent research project (funded by an REU grant from the NSF). As I’ve written previously, my experience studying the evolution of an alpine plant’s […]

Searching for the World’s Worst Glass of Water

It takes a few days to adjust to life at 13,300 feet in Potosi, Bolivia. As soon as I touched down in the tiny airport, I remembered the time I climbed Mt. Whitney and got desperately sick in camp at 13,000 feet. Whitney is the highest point in the lower 48 at 14,500. To visit […]

Plugging In

Two weeks ago, for the first time in 15 years, I flushed the toilet inside my house. This — and by “this” I mean the 15 years of non-flushing — was not quite as gross as it might sound. Until very recently, my family and I lived off the electrical grid in rural Colorado, in […]

Digits of the Devil

On Sunday evening, I was standing in our orchard watching the sunset when I turned around and saw a strange beam of light that appeared to rise from the east, directly opposite the setting sun. Crepuscular rays or “God’s Fingers” are pretty common around here, but usually these majestic light rays emanate from the sun. […]

Guest Post: Enough With the Spin

“In the 1960s we noticed there was a problem with time,” says Witold Fraczek, an analyst at Environmental Systems Research Institute in Greater Los Angeles. In 1948 Harold Lyons at the National Bureau of Standards in Washington, D.C. built the world’s first atomic clock, an instrument that keeps time based on the vibration of atoms […]

Dust on our crust

Spring is a nervous time for skiers and farmers. I’m both of these, and every April I watch the weather even more closely than usual. As a skier, I’m waiting for crust — the year’s most magnificent snow conditions. Spring’s warm temperatures compress the winter’s deep snowpack and when the freeze/thaw cycles line up just […]

The Xenotopian Impulse

Until last week, I’d never heard of the Broomway. Now I long to walk it. The Broomway is a paradox: a path through the ocean, a six-century-old walkway that disappears each day. It begins on the southeastern coast of England and heads straight out to sea, crossing about three miles of sand and mudflats until […]
