Last night SourDiesel and I went on a big exploration. We explored a drain deep under Fairfield. First, we went south in the direction of the outfall. When we got to the weird outfall thingy, we heard big waves. And we remembered JP and Tanuki's experience. So we went North quite quickly.
We were hoping to see a lift station, it turns out the Eberts station was next to the drain, separated by brick and rock. The metal thing on the ground in one of the pix is where water was gathered,siphoned down an adjacent tube, and then pumped to the hidden lift station.
Further north, we came across the concrete pipe. At the end of it, it turned into a totally crawlable brick tunnel. This mini-tunnel actually goes and does a two block loop before re-connecting to the main tunnel.
As for the 2 backreaker offshoots on my maps, it turns out that while they do exist, they are separated from the main tunnel by several feet of rock.
while they do run parallel to the tunnel, they do not actually connect to it.
Further north, we came across a 10 minute long section that had the most stunningly awesome stalactite calcite formations. It felt like we were in the ribcage of a whale.
We didn't get to do the entire drain. While not fully walkable as i had previously thought, the drain totally maintains its size as it goes north. I have to say, it is a much more traversable and much cleaner drain than the Cecelia creek system.
Anyways, i think we got more than we bargained for, in a good way! A beautiful drain, i'd love to check out the far northern section some other time.
And it was a real pleasure to explore with you, SourDiesel, you were really fun to explore with!
