A Southern Washington Lava Tube, July 2023.

This cave is possibly the second-longest lava tube in North America. It's somewhat known by locals, so unfortunately bears the scars of visitation by an unknowing, uncaring public. Lava caves cannot clean themselves out, nor can they regenerate.

It's a more complex lava tube than most - it has at least three branching passages above the main channel. Two are meanders from when the flowing lava river was at a higher level, and another is a channel that branches off downstream. I cannot find a modern survey of it, so the true length of these branches and the cave itself is unknown to me. The entrance of the cave is steep, and the opening is small. The setting allows a moss and fern garden to grow green in the misty daylight until it is choked out by the dark.

This cave surprised me with how tall and narrow it is - ceilings are often in excess of 40 feet (~11 m), carving a winding void into the earth. The floor is very rugged, and made of breakdown (collapse debris) for most of its length. We never reached the end, unprepared for how long it would take to finish the remaining third of the cave. A return is in order after the thaw.

BOOKS.

I've been hunting around for reference books for TDA and while on my quest I found three guides for Age of Empires, the original manual for the first Age of Empires, and the original manual for Empire Earth! I am a HUGE nerd for the first two Age of Empires games, like Age 2 ranks as one of, if not my most, favorite game of all time. Finding these (and for cheap! these were all $4 each!) was an AWESOME find, I love finding books about things I love. Empire Earth is another RTS game I used to play way back in the day. I still have the original box for this game somewhere, but I didn't know if I had the original manual inside. It was only $3, so I picked it up too. It's HUGE.

And I did indeed find some great reference books! The Photoshop one was a happenstance find that I decided to pick up, but the two books on gun care and ballistics are AWESOME! I have to do a lot of research about guns for TDA because Rez is supposed to be a gun expert, and I am very much not. These are both from the 70's, but the information in them is fantastic, exactly what I'm looking for. The ballistics one is actually really cool, talking about and showing different types of bullets and their usages. I still need more gun books, as I need a few for modern gun care. Told the owner of the store when I was buying them "I'm a writer, I swear, I need these for research."

#right now i'm looking for geology books about the landscape of north idaho and washington

Much of western Washington's recent geology has been dominated by giant ice sheets stretching from the Canadian Rockies to central Washington. This ice gouged out the Salish Sea, Puget Sound, and carved up the rest of the landscape. Port Townsend sits on a peninsula made up of the junk giant glaciers left behind. This is typically sandstone, gravel, and mud but weird stuff starts happening when the giant glacier meets the ocean and starts to melt. There's lots of cool geology in Port Townsend, once you know where to look!

The only Cool Rock(tm) I found in the Green River near Auburn a week and a half ago, just before I got officially engaged to @kkatieclarkk, a well tumbled, partially agatized piece of petrified wood. Documenting here so I can eventually slice and polish it up for multiple pieces of jewelry for us both??! #rock #rocks #silica #rockhounding #Washington #rockhound #geology #agate #agates #quartz #crystal #crystals #calcite #zeolite #zeolites #mineral #minerals #collection #earth #geo #nature #pnw #pacificnorthwest #mining #wood #petrifiedwood #fossil #fossils #fossilwood #woodgrain (at Kanaskat-Palmer State Park) https://www.instagram.com/p/CeUZk5RPXwu/?igshid=NGJjMDIxMWI=
