Lassen Volcanic National Park Retro Graphic Tee for Hikers

Lassen Volcanic National Park in northern California is home to all four types of volcanoes found on Earth, plug dome, shield, cinder cone, and composite, making it one of the most geologically diverse parks in the country. Lassen Peak last erupted between 1914 and 1917, making it the most recently active volcano in the contiguous United States before Mount St. Helens. The park's hydrothermal features, boiling mud pots, fumaroles, and hot springs, remain active today, a reminder that this is living volcanic terrain. This retro graphic tee captures that energy with bold stacked lettering and hydrothermal steam woven into the design. Wear it hiking Bumpass Hell, one of the park's most popular hydrothermal areas, or on any day you want to represent one of California's most underrated national parks. A thoughtful gift for the geology enthusiast and Sierra Nevada explorer.
