This is Mt. Lassen. It's another volcano, the last one for us. We came up here more to look at the nearby lava tubes which someone told Dave about. We did take a look around the "devastated area" from the 1915 eruption, and got some educational-like info on different igneous rock types.
One of Dave's online buddies told him about the lava tubes near Lassen, so we went hunting for them. It's totally different from other cave formations, having been sculpted inside by the flowing and cooling processes of lava.
Subway Cave Lava Tube
Subway Cave was discovered because it crumbled in on itself. (The remaining roof is quite stable, it seems the cave-in was something that happened due to heat when the tube was active.) It's far too dark inside for video--in fact, we even had trouble taking photos with the flash because it didn't light the cave sufficiently for a viewable picture.
Interviewing kids tends to make up for such things, though.

Issac is really enjoying your posts on the volcanoes. Here is his comment: "I know about volcanoes and I like the pictures of volcanoes you posted. I didn't know about lava tubes. I thought the lava tubes would be small, like a box or something. It was cool watching you go into the lava tube. I bet it was two stories high. I liked watching her go down the railing. Thank you for the video and the pictures."
