Powder Days

This week, I was reading a story from a few years ago about what the last snow on earth might look like. Snow algae, which occur naturally in the snowpack, rise to the surface during the spring; when they emerge, they turn red. This  “watermelon snow,” these days, could be seen as a warning. The […]

How Snow Falling on Pines Changes the Forest

Snow falls often where I live now. I love it, mostly. I do like to work, so I don’t love when it creates snow days. But I love its crisp delicacy, falling soft and softly falling. I love its silence and its brightness. I love the way it tattles on the deer and turkeys and […]

A Vocabulary for the Almost-Disappeared

“Look, our snowman is still there,” I said Monday morning. “Oh!” my daughter said. “It is! Mommy, will it be there for all the times?” I picked her up. “No, it won’t,” I said. “I think it will melt. Remember how we talked about snow melting?” “Oh,” my 3-year-old said. “Okay.” Her disappointment was audible. I […]

Redux: Dust on our crust

This post first appeared on April 24, 2013. Unfortunately, the problem of dust on snow has not gone away. Since I wrote this post, NASA has gotten involved in studying snow on the Grand Mesa. I wrote about the NASA project for FiveThirtyEight. Spring is a nervous time for skiers and farmers. I’m both of these, […]

Redux: A Snow Day

The last few days in Washington have been beautiful, springlike. Soft breezes, temperature in the 60s and 70s. Which would be fine, if it were spring. But it is February, and it is not fine. This weather is making me angry. I try to enjoy it, because it’s what we have, and it is, objectively, […]

Redux: Below the Snow

Right now, the meteorological event that some are calling Winter Storm Kayla is on its way across the U.S. While people may be curled up inside with a quilt by the fire, another group of creatures is finding shelter outside, under a cold, white blanket. This post about that unique below-the-snow spot, called the subnivium, originally ran in […]

A Snow Day

The first snow of the year, and the first noticeable snow of this winter, fell here in D.C. on Tuesday. Yes, we know that our reaction to snow makes no sense. No, we don’t have enough snowplows. No, we don’t know how to drive in snow. You’re very clever for noticing, People Who Live In […]

Freezeproof a Fairy—With Science!

Tom Painter, a research scientist at NASA’s Jet Propulsion Laboratory in Pasadena, studies snow hydrology in mountains around the world. He’s also a leading expert on the thermodynamics of fairies and princesses. Painter started his fairy-princess sideline a few years ago, when he was asked to lend his expertise to Tinkerbell: Secret of the Wings. In the movie—bear with […]
