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.

The awe-inspiring beauty of the Brockville Railway Tunnel, showcasing a stunning formation of stalactites and stalagmites. These natural sculptures are formed over thousands of years as water drips from the ceiling of the cave, depositing minerals that gradually accumulate. The stalactites hang from the ceiling like icicles, while stalagmites rise from the floor, both glowing under the warm illumination. The tunnel, which is Canada's first railway tunnel, was completed in 1860 and is a testament to the country's rich history of railway construction.

Since everybody seemed to enjoy my other cave photos, here’s some more detail shots of a different area in this cave system. This area used to be underwater, causing the bubbly formations.
You can see in these photos where the water level was.
So interesting all of the different things a bit of rocks, water and time can create

The Little Cave Soldier. He was found on a ledge guarding the path through the cave.
