Mud Boiling at Lassen Volcanic National Park

At Lassen Volcanic National Park, I was surprised by just how volcanic it was, everywhere. And yes, I know it’s in the name. But I was not expecting lava rock to be everywhere and for all the lakes & springs to have a whiff of sulfur and boiling water to them. It feels like the Earth is genuinely alive & active beneath your feet (which, in fairness, it is..). Boiling Hot Springs Lake in the Warner Valley is a little off the beaten track, but we had it all to ourselves on a summer weekend.
