Eight backcountry skiers were found dead and one remains missing after an avalanche near Lake Tahoe, authorities said Wednesday. The avalanche in Northern California's Sierra Nevada mountains is one of the deadliest in U.S. history. Here's a look at the others:

A massive wall of snow swept two Great Northern passenger trains into a gorge, killing 96 people. The trains had been stuck on the tracks for days because of bad weather, and some passengers had trekked into town, likely saving their lives.

In the most deadly event of the Klondike Gold Rush, a series of snow slides in April 1898 killed around 65 people on the Chilkoot Trail.

Ten climbers and a guide were killed by a massive ice avalanche on the Ingraham Glacier, the most deadly mountaineering accident in U.S. history.

An avalanche wiped out several homes in the town of Twin Lakes near Independence Pass, killing seven residents, including five children.

An avalanche crashed into the Alpine Meadows Ski Resort near Lake Tahoe, killing seven people, including four resort employees who remained on site even though the resort had been closed for the day because of the dangerous conditions. A 22-year-old chairlift operator was rescued five days later after a specially trained dog found her in the remains of the ski chalet.
