Panum Crater is a other great outdoors located in United States.
California United States
I highly recommend driving out to this place and walking up the top. The view is breathtaking, and the obsidian and puma stones are wicked cool. Be prepared for a long bumpy ride down a dirt road .
Walk the whole crater: plug and outer rim. Black shiny rock is obsidian . Pick up a pumice stone to feel its weight.
Make sure you have a couple of hours to check out both trails (Rim and Plug Trails ).
Check out the exhibits inside to give some good history and science about the lake's formation. Great bookstore too! - Lolly W
Incredible place, otherworldly feel. Go at sunset. - Maarit Olkkola
