Oregon

By Travelog Editorial Team · Updated August 8, 2026

Oregon is live on Travelog with one city, Crater Lake, home to Crater Lake National Park, Oregon's only national park. Entrance costs $30 per vehicle in summer and $20 in winter, valid 7 days either way. The lake formed after Mount Mazama's volcanic collapse roughly 7,700 years ago, an event ancestors of the Klamath people actually witnessed, an eruption confirmed by documented archaeological evidence: sagebrush-bark sandals recovered from beneath the volcanic ash layer.

The documented archaeological evidence connecting a living oral tradition to an actual 7,700-year-old geological event is worth understanding before visiting, covered in full below.
