There's regular snow. And then there's Sierra snow.
The Sierra Nevada is one of the snowiest places on Earth. We're talking about a mountain range that can get 50+ feet of snow in a single winter. Storms that bury cars, close highways for days, and remind everyone that nature is absolutely in charge.
I've lived through some wild ones. But the historical records? Those make my stories look tame.
Here's a look at the storms that shaped this place—and what they teach us about living in snow country.
The Numbers That Don't Seem Real
Before we get into specific storms, let's talk about what the Sierra is capable of:
- Tamarack, CA (1911): 73.5 feet of snow in a single season. That's not a typo. Nearly 75 feet.
- Donner Summit average: 400+ inches annually in a normal year
- Single storm potential: 10+ feet in 3-5 days is not unusual
These mountains catch Pacific storms like a catcher's mitt. All that moisture hits the Sierra, rises, cools, and dumps. Over and over and over.
The Donner Party Winter (1846-47)
You can't talk about Sierra snow without talking about this.
The Donner Party got trapped in the mountains in late October 1846 by early, heavy snow. What followed was one of the most harrowing survival stories in American history.
That winter dumped an estimated 22+ feet of snow at what's now Donner Pass. The migrants couldn't move forward or back. They built shelters, ran out of food, and... well, you know the rest.
What it taught us: Respect the timing. The Sierra can turn hostile fast. Early snowstorms happen, and when they do, the mountains don't care about your plans.
Today, there's a reason Donner Pass has some of the most robust snow-clearing infrastructure in the country.
The Big One: January 1952
This storm is still referenced by old-timers as the benchmark.
In January 1952, a series of storms absolutely buried the Sierra. Donner Summit recorded 149 inches (over 12 feet) in just 6 days. The cumulative total for the month was over 300 inches.
Trains were trapped. Highways were closed for weeks. The town of Truckee was completely cut off. People were skiing TO the grocery store because it was the only way to get there.
What it taught us: Even with modern infrastructure, the Sierra can shut everything down. You either learn to live with it or you don't live here.
The Winter of 2016-17
This one's recent enough that I remember every detail.
After years of drought, the Sierra got absolutely hammered. Mammoth Mountain recorded 618 inches (51.5 feet) of snow. Squaw Valley (now Palisades) got over 700 inches.
The snowpack was so deep that ski resorts stayed open into July. Roads were carved through 20-foot snowbanks. The lakes filled back up. The drought broke.
I remember driving through Mammoth that spring—the road was a canyon of snow, walls higher than my car on both sides. It was surreal.
What it taught us: The Sierra can recover fast. And when it snows here, it SNOWS.
March Miracle Storms
Some of the biggest dumps happen when you least expect them.
The "March Miracle" is a phenomenon where late-season storms save an otherwise mediocre ski year. It's happened multiple times:
- March 1991: Over 200 inches in a single month at some resorts
- March 2011: Multiple feet just when everyone thought winter was over
- March 2023: Record late-season snow extended seasons into May
What it taught us: Don't put away your snow gear until May. The Sierra always has one more surprise.
The Human Element
Here's the thing about big Sierra storms—they're inconvenient, sometimes dangerous, and also kind of magical.
Yes, you might get stuck. Your power might go out. The highway might close. You'll shovel more than you thought possible.
But there's also this: fresh snow muffling every sound. The world turned quiet and white. Skiing powder so deep you're literally floating. Neighbors helping neighbors dig out. The particular joy of being snowed in with good people and nowhere to be.
Living here means accepting both parts.
Storm Prep 101 (From Someone Who's Learned)
If you're going to spend time in the Sierra during winter, here's what I keep on hand:
In the car:
- Chains (and know how to put them on BEFORE you need them)
- Blankets, snacks, water
- Full tank of gas before any storm
- Shovel, ice scraper, flashlight
At home:
- 3+ days of food and water
- Backup heat source
- Flashlights, batteries, candles
- Full phone charge when storms are forecast
Mindset:
- Plans change. That's fine.
- Storms are temporary. The powder is worth it.
- Check Caltrans before driving. Always.
The Respect
Every big storm is a reminder: we live in the mountains on the mountains' terms.
The Sierra has been doing this for millions of years. It'll keep doing it long after we're gone. Our job is to enjoy it, prepare for it, and respect the power of it.
I've never regretted a storm day. Some of my best memories are from being snowed in, making soup, watching it pile up outside. The mountains give you these moments if you're willing to receive them.
