Wildland Fire

Visitors may see smoke from wildland fires on various park trails.

Thunderstorms are common during summer and fall in the Lassen area. Each year, lightning strikes result in wildland fires that help shape the Wilderness around the country. Each year, several of these lightning ignited fires are managed for the benefit of natural and cultural resources. Visitors to Lassen Volcanic National Park may see smoke from these fires from various park viewpoints.

Over 75 percent of Lassen Volcanic National Park is designated Wilderness. Lightning fires are allowed to burn in these particular zones, under specific conditions, and with close monitoring by park fire staff. Factors such as fire behavior, fuel loads, weather conditions, air quality, and potential threats to people and property are used to determine the ability to manage these fires.
