The Snail Tunnel
This tunnel used to drive me nuts since I passed it on my way to work all the time.  I had a pretty good idea where it led, but I figured we would give it a shot anyway to see what was underground.  So how did this tunnel get its name?  Well, read on and find out.
The outfall pours out into this canal and makes its way to the Trinity River a couple miles from here.
The outfall itself is pretty big though, so we were hoping for something interesting upstream.
I swear this wasn't posed.  This is just on the other side of the outfall as Dani ponders what to do next.
At this point it split up into a bunch of tunnels.
You can see through the walls roughly how many there were.
I blasted an air horn in here just for the hell of it, and the reverb lasted forever.  Almost as long as the ringing in my ears did afterward, in fact.
I like how this opened out to reveal that the next section was all covered over like something exotic.
I've got the Indiana Jones theme running through my head right here.
A short while later we finally found the end of the tunnel...
...that was fed by the lake at the top of the incline.

So how did we end up calling it the "snail tunnel"?
There were hundreds of the guys mixed in among the algae and pollution.
Here are still more little guys (Those are snails, not pebbles).
I guess the snails made good food for the swallows that love big wide-open tunnels like this.
