The Drop-Off, Part 2
Naturally, I was dying to find out what was at the top of the huge Drop Off we observed from the canoe the last time, so Dani and I went on a scouting mission the week before this expedition.  With some perseverance, we finally found an entrance, although I didn't get around to checking it out until the next weekend with Elizabeth.

Unlike virtually every other tunnel we've ever explored, this one required a little more effort to get into.  Basically, we had to jump down a curbside drain, then crawl 15 to 20 feet through this pipe to enter the tunnel. 

There's more detail about how I found this spot and scouted it out in one of the journal entries.

That's Elizabeth thanking her genes for a metabolism that allowed her to get into tight spaces while cursing her claustrophobia that almost wouldn't.

This tunnel shared the archway design common to so many throughout Dallas.

The washed-out look of this image was an unfortunate effect of pushing the brightness parameter of my gfx editor to impossible degrees.  The original image was pitch black except for the singular spot of the flashlight in my hand.

The first thing we did was to head downstream toward the Drop-Off itself.  Sure, we wanted to know what was upstream, but this was the whole reason for going down here.  You could hear the roar of the water in the distance, so we went toward that end first.
At several points throughout this tunnel we found spots where water "sprouted" from cracks in the walls, floor, or ceiling.  Pretty scary.

And for the boot fetish people out there, you owe me for this shot.

This was a small concrete damn just a little upstream from the Drop Off itself.  Considering the goal is to get water out of the tunnels, I have no idea what it was there for.  Any ideas?

And here it is!

This is one side of the Drop Off itself.  The grate we looked through from the canoe last time is just above the water at the bottom of the incline.

If it weren't for the Prozac, I would have been at the bottom.

There's Elizabeth from a more a straight-on angle in front of the Drop Off. 

If it wasn't for the Haldol, I so would have pushed her to the bottom.

This is a view down the edge of the "cliff."  You can see the hand rungs along the side.  For scalar reference, they're maybe 3 or 4 inches across.  The drop is probably about 10 feet or so.

The tunnel in the distance was open and not submerged (unlike downstream; see relevant journal entry), but it was difficult to photograph because it was relatively far away from the flash.

After the Drop Off, we doubled back and went upstream.  The area shown here is where the tunnel's archway shape switched over to the more rectangular configuration.
