Lassen Peak rises to 10,457 ft in Pacific-Ranges within the Cascade Range range.

Standing at an elevation of 10,457 feet (3,187 meters), it is the southernmost active volcano in the Cascade Range. Lassen Peak is part of the Lassen Volcanic National Park and offers adventurers a range of outdoor activities throughout the year.

During the winter season, Lassen Peak receives heavy snowfall due to its high elevation. The snowpack can vary greatly, ranging from 10 to 55 feet (3 to 17 meters), making it a popular destination for winter sports enthusiasts. The mountain's snow-covered slopes provide excellent opportunities for skiing, snowboarding, snowshoeing, and other winter activities.

Lassen Peak is also known for its significant hydrological features. Several creeks and rivers within the region receive runoff from the mountain, including Kings Creek, Hat Creek, and Manzanita Creek. These waterways contribute to the diverse ecosystem and provide habitat for various plant and animal species.

The name of Lassen Peak originates from Peter Lassen, a Danish-American explorer who played a significant role in the settlement of Northern California during the mid-19th century. The mountain holds an intriguing history and folklore, including stories of the indigenous people who resided in the area, tales of volcanic eruptions, and legends surrounding the creation of nearby geological formations.

It is crucial to verify the information across multiple independent sources to ensure accuracy and obtain a comprehensive understanding of Lassen Peak and its surrounding features.

{# FAVORITE-LIMIT MODAL — fires when a non-premium user hits the 3-favorite cap. Mirrors the iOS PremiumGateSheet's .bookmarkLimit case: same copy direction (limit reached → unlimited with Premium), same primary CTA shape.

Push-notification alerts (snow / flow / buoy / ski) are managed in the iOS app because they require APNs + device tokens; the webapp has no equivalent surface, so the right thing to do is point users at the App Store.
