True. There are volcanic landforms - hinting of past and possible
future(!) eruptions - all over the western United States if one knows where to look, and how to recognize them. From ancient desert lava flows to towering peaks. They are, literally, everywhere. California, Oregon, Washington, British Columbia, Idaho, Arizona, New Mexico, Wyoming – I could go on and on!!
These are particularly prevalent in the Pacific Northwest along the spine of the Cascades - from Central California to Canada. Thousands of them. Perhaps even tens of thousands.

Its a deep, subterranean filled volcanic lake. Icy cold. NW of Elgin stands a knob. It is the beginning of a new peak formation. I've been told that a woman owns part of it that has natural ice caves in the dormant vent tubes. She occasionally used to take people through them.
Wow. Sounds like you live in my kind of place. I am unfamiliar with this part of Oregon, but it sounds very interesting!
What is a “vent tube”? I am familiar with lava tube caves, but am not sure what a vent tube is. Please tell me more!

Sorry if I'm getting too technical for a lot of people here. My dad and uncle (both gone now) owned, during their time, the worlds leading geotechnical company. Rock formations and geology were frequent discussions wherever we went.
Interesting! What is a "tiny caldera"? Considering the massive explosive processes involved in caldera formation, it is difficult for me to picture a 'tiny' caldera. Please tell me more! How big is it?

We could have spent weeks there. I wanted to go back and do an opal mining day trip in an old vent, but never got to it.
I have not visited the Oregon ice caves (are you speaking of the lava tube caves at Newberry Volcano, i.e. Newberry National Volcanic Monument?). When I visited Newberry, I had my dog with me, and he had to remain in the car. I took the time to do a short hike through the Big Obsidian Flow there, but didn’t want to be away from the car so long as to allow a stroll through a lava tube.
As for Idaho – WHOA, lots of interesting volcanic areas in Idaho. I visited Craters of the Moon National Monument in Idaho in 2018 – an AMAZING volcanic area, not just the monument itself, but for miles and miles all around – and, of course, nearby Yellowstone volcano on the same trip.
I have visited the lava tube ice cave in Lava Beds National Monument, on the slopes of the mighty Medicine Lake Volcano in far north-eastern California. Impressive! This was many years ago - visited on a day that was maybe 100 degrees - had heard of the ice cave there, didn't believe it possible - but it was!!
How did you come to find your home in north-eastern Oregon? What drew you to that area?
Hey, thanks! This is being interesting and fun. Takes one's mind off the current 'situation'.
Let the discussion continue!!
