Lassen Volcanic N. P. - USA

I didn’t know about this park until a month ago. The United States has 63 designated national parks, and this is one of the few I've never heard of. It is great to learn about new places.

Nestled in the peaceful forests and wilderness of Northern California is Lassen Volcanic National Park. Lassen Peak is the largest plug dome volcano in the world and the southernmost volcano in the Cascade Range.

Established in 1916, Lassen Volcanic National Park is home to meadows freckled with wildflowers, clear mountain lakes and numerous volcanoes. A closer look at the landscape, however, reveals the hissing fumaroles and boiling mud pots that still shape and change the land, evidence of Lassen's fiery volcanic past. - in: https://www.nationalparks.org
