3 Days in Crater Lake National Park, Ore.

Roughly 7,700 years ago, high in the southern reaches of the Cascade Range, the 12,000-foot Mt. Mazama began to erupt with astonishing force. Over the course of several days, the volcano released a towering column of pumice and ash that reached 30 miles into the atmosphere, spewing debris across 656,000 square miles of what is now the western United States and southwestern Canada.

3 Days in Tofino, British Columbia

On November 4, 1875, under dark skies and a mounting gale, the sidewheeler Pacific collided with the sailing ship Orpheus as it rounded Cape Flattery en route to San Francisco. The Pacific sank almost immediately; only two of its 250 passengers and crew lived to tell the tale.

Orcas Island

3 Days on Orcas Island, Wash.

In the waning days of this past July, a killer whale—soon to be known to the world as Tahlequah—gave birth to a calf in the waters off the coast of Victoria, British Columbia. The event was a cause for celebration for Tahlequah’s endangered pod, whose 75 members had not seen a live birth in nearly three years. But within less than an hour, the calf had stopped moving.

Kerry Park

3 Days in Seattle, Wash.

Like so many adolescents who reached their formative years in an era of grunge, my introduction to Seattle came through music. I first heard its beauty in the voice of Chris Cornell, and I felt its darkness and melancholy in Kurt Cobain’s anguished howl. The city was strangely captivating for a place I’d never been—sparkling blue in summer, misty gray all winter, and the source of so much that channeled my teenage emotions.

3 Days on Whidbey Island, Wash.

As the 18th century came to a close, the British explorer George Vancouver set sail to survey the wild coast of the Pacific Northwest. Among his findings was a narrow pass at the tip of Fidalgo Island, where the tides moved with such force that Vancouver believed he had found the mouth of a great river. It wasn’t until his lieutenant, Joseph Whidbey, explored further that he realized he had discovered a second island—one that stood on the other side of this confounding Deception Pass.
