Besides, it had gotten uncomfortably warm at Pit River. And the flies were starting to annoy me. Time to move on.
So I headed toward Lassen Peak. The higher altitude means a nice temperature drop. And getting out of the valley allows for more constant breezes.

There are several campgrounds along highway 89, between Burney and Lassen Volcanic National Park. However, a past forest fire through the area meant some of them are closed and others are not very inviting unless you like a view of burned trees.
Cave Campground (which gets its name from a lava tube cave on the other side of the highway) was open and appealing, even though it's right on the highway. I found a site away from the generator people, with a lava outcropping that blocked some of the road noise. The temperature was perfect and only the occasional fly buzzed through the Rolling Steel Tent. And though the campground was rather full, it was quiet.
