This deep culvert was discovered by Dan Helsing who first walked its length from the infall to the falls with nckt where they couldn't continue without rope.
The following night I tagged along with them and we headed up through the outfall.
It starts as a concrete box with a plughole draining into it.
This way to my secret lair...
Dan Helsing keeps a look out...
From here it gets rocky and bastardly treacherous. Proceed with caution. Seriously.
It then opens up into the chamber that Dan and nckt reached the night before. WOW. The chamber is vast and echoes the sound of the water hammering down onto the rocks below both falls. I'm sure I have tinnitus from that place.
