Before Lassen Peak last erupted, in 1915, it was thought to be dormant. It’s now thought to be dormant again. The mountain, which is part of the southern end of the North Cascades, and the landscape over which the mountain presides, now form Lassen Volcanic National Park, a place that is a combination of typical northern California landscape and ruinous volcanic-aftermath landscape. Some of the park is still geologically active, with boiling water, hot streams, fumaroles, sulfur vents, and steam holes. Blue lakes contrast with golden flakes of iron pyrite; wildflowers grow near cinder crags.

Like all of the North Cascades, Lassen Volcanic National Park is covered with snow for much of the year. The road to Lake Helen is sometimes buried under 40 feet! So, get out your snowshoes or cross-country skis and pack a winter picnic. In the summer, there’s plenty of hiking, boating, kayaking, swimming, and even horseback-riding.
