Thank you for activating a core memory from when I toured this at age 9 or 10 while visiting Sunriver. It's awesome to get some new info about the area, and I appreciate the addition of CC!
No shortage of great places to visit in Central Oregon! TH-cam’s auto caption generator is getting so good that editing the auto-caption text is trivial for short videos. Always worth the effort.
Went in to those tubes back when I was 11 or 12 years old. Lanterns works better for seeing in there. It was a hot summer, we didn’t want to go back to the car(102 degrees Fahrenheit).
I visited this cave a few weeks ago. It was a fun underground hike. Tips for anyone planning a visit: It is slow going because of irregularities in the floor of the cave; if you aren't careful you'll trip on something. You have to constantly move the flashlight down to look at the ground (to make sure you don't trip) and then up to see the cave. If you don't have your own flashlight, you can rent one for a about $5. You must have a reservation. Reservations go on sale 1 or 2 days early and they go fast. There are bathrooms near the parking lot; use them if you think you will need to go. There's nowhere to go in the cave. Bring a light jacket or sweatshirt, it is a somewhat cold in the cave.
If I’m understanding you correctly… lava tubes form basically as soon as a fluid lava flow establishes a stable flow path. They’ll live as long as the lava supply lasts, sometimes for many years (like on Kīlauea before 2017). The insides of lava flows are well insulated and can remain hot enough to be a little gooey for about a month depending on thickness (according to one paper I looked at). It’s during this time that features like the veneered sides and collapses are happening. This is when lava contracts most and therefore when probably 90% of large-scale collapse happens.
Actually, it's very well-known what's beyond the sign at the end of the cave. I've crawled down to the very end of it myself. About 100 years ago for several months a couple local guys dug out the end and created the ditch and tailings you see through the sand. They got about 400 feet when they discovered the ceiling came down to meet the floor, which meant the end of the cave. Look, you gotta know that if there were any more to that cave it would be well-dug out and well-known. Not only has this been a tourist cave for a century or so, but this part of Oregon is crawling with cave moles like myself that don't let any leads go unexplored. . . Great video, otherwise!
Me and friends went into the deeper part of the tube where that sign is. It widens out to a small 4 foot high cave, then shrinks down to army crawling again. Those sand areas were not fenced off, nor was the back of the cave back then. We had the smallest of our group ahead of us and told him we'd pull him out if he got stuck!

Very informative colonoscopy through Mother Nature’s intestines. Rock on Andrew!
🤔
Me and a friend of mine walked all the way to the end of the cave where it's plugged with sand. That was 1977.

Aren't reservations primarily for guided tours?
This was so fun and informative - thank you so much for the tour!
Really interesting! Great video. Learned lots. Thank you from England.
Glad you enjoyed!
Cool! I’ve explored the lava tubes at Craters of the Moon, but never did this one.
There is no shortage of lava tubes in the Northwest!
Ha ha cool. A new video 👍🏻
Once in a while I get to it 🙃
Curious as to the timeline on a lava tube. Like from eruption until cool down, let’s say ambient temperature of the surrounding area

Word is the last Kilauea megaeruption in 2018 that flooded Leilani Estates is still stupid hot!

Maybe a Ape Caves tour also?
I’d love to! That’s a much longer and wetter cave so it’s a more challenging shoot.

I did that too when I was little. I enjoy a good lava tube crawl!
