The Cascade Mountains stretch from southern British Columbia, Canada, all the way into northern California. Part of the famed Ring of Fire – a string of volcanoes and mountains running throughout the Pacific Ocean – the southern Cascades contain hundreds of small to medium-sized volcanoes. This includes more than 30 volcanoes that make up California’s Lassen Volcanic National Park.

This week marks the 100th anniversary of one of Lassen’s most powerful volcanic eruptions.
