Beaver Tunnel: Yet Another Trip
Yes, I've been here many times before, but Silent Search and Dokk hadn't seen it yet, and it's such a cool tunnel.  As it turned out, there were still a few  things left to be discovered.

This is quite a ways into the tunnel.  There's a side tunnel that used to connect to the main one (pictured) through this hole that was carved into its side.

However, if you go a short ways (well, a few hundred feet) upstream, you find that there hasn't been a flow in here for quite some time.  It is sealed off at this end with cinder blocks.

Basically, this section does nothing these days other than capture humidity.  You can see it in the picture making the whole image somewhat gray, and even though it was August, you could blow steam out your breath like it was a cold day.  You can see condensation collecting all over the walls.

In one section there was graffiti carved into the walls.  This section wasn't formed concrete the way most areas are.  Actually, it looked like it was applied with a trowel.

This is one of the better shots we collected.  This part said Oct 23, 1901.  You can also see the texture of the concrete better with the light coming from the side.

Another image of the graffiti.  Obviously this had to have been written into the concrete when it was still wet, and why would anyone go to the trouble as a prank in one of the least-likely places for it to be discovered?

I'd been meaning to do this for a while, and this time I had guys with me so I could get a boost up to these rungs.  The hole in the side of the manhole cover is just large enough to get the GPS out of and give me an idea where this location was.

Same thing with the flash this time.  You can see the last rung was a few feet above the top of the main tunnel, and that was already almost out of my reach.

A really old area with a tiny side tunnel.  I have no idea what was spray painted above it.  Most of the city's markers like this make no sense to me.

A neat close-up shot Dokk took (the copyright watermark should be his, actually).

This is one of the things I point out to explorers: You need a frame of reference in your images if you want the viewer to understand what they're seeing.

Aesthetics are great (like here), but most people won't get the scale of what they're looking at.  Are these rocks three feet high or three inches?  You can figure it out thanks to the water (i.e., no actual white caps), but in some shots, it's extremely hard to tell.

Actual size?  Not so impressive.

A small side tunnel with grass sprouting in it.  Grass seeds get washed down here and have plenty of water to sustain them, but there's no light, so they don't get much taller than this before withering away and being washed out with the rains.

One of the wider sections that is naturally lit by curbside drains.

Close-ups of a couple soda straw formations.

Taking a break.  It was pretty hot in here even though it was in the shade, obviously.
