...But wait a minute, bluebonnets flower in Texas in the spring and this is August.
But surely this has to be Yellowstone, with fumaroles and mud pots and stinky sulphurous air. But I am not in Yellowstone.
Here's another clue.
If you haven't guessed yet, I'm in Lassen Volcanic National Park. This is one of the lesser known National Parks situated in Northeastern California and boasting the largest plug dome volcano in the world, Lassen Peak. It last erupted in 1915.
We spent 2 days in the park, hiking the trails and enjoying the clear mountain air and the cool nights. Here are a few photos of one of our great National Parks.
