Mt. Rainier sunrise sketch by Chandler O'Leary

A lot of people are going to be up early today to participate in holiday craziness—but for me, this time of year has a completely different incentive to be out before the sun. Because if you live in the South Sound area and you’re very, very lucky, you might catch that rare phenomenon where the sun rises behind Mt. Rainier and casts a massive shadow on the clouds above.

The moment doesn’t last long—about the same amount of seconds as alpenglow does. And the conditions have to be absolutely perfect for it to happen: clear enough for the mountain and sun to be visible (which almost never happens in winter), but with just enough mid-level cloud cover to give the shadow a reflecting surface. And you can only see it from certain areas where the sunrise is perfectly aligned behind the mountain (like the solstice sunrises with which places like Stonehenge and Mission San Juan Bautista are intentionally aligned). All of this makes it so uncommon that we’re lucky if conditions are right once a year.

In my six-plus years here, I’ve only seen it in person twice—and on Monday, I was finally lying in wait with my sketchbook. It felt like winning the lottery.

Pin it!
