[edit] Tunnel

  • I talked to my mom tonight about this underground river. She worked at the Federal Reserve building from the 1960s until the 1990s and she said there is a tunnel connecting that building to the old Post Office (now the Federal Courthouse Building) that faces south on 5th Avenue North. She has been in it before. She said they told her that the tunnel would flood because of the underground river. --Wheresdib 20:58, 28 August 2007 (PDT)
  • I'm beginning to think that people are routinely mistaking ground water for an "underground river". --Dystopos 21:01, 28 August 2007 (PDT)
  • You think? I am pretty sure that unless someone can take me to the basement of the McWane Center and put me on a boat in the river, it was just a big hoax. Yes, Birmingham is built on limestone and yes there are lots of old mines, but surely if there really was a huge river we would know about it. I am in the process of creating a map showing where this "river" would flow, according to all the "sightings". --Wheresdib 06:44, 29 August 2007 (PDT)
  • I flipped through my big USGS folio on the Geology of the Birmingham Quadrangle. Nothing specific about caverns or underground rivers. There was a tidbit I hadn't thought about, which is that Jones Valley is only a "valley" because its bounded by ridges, but its also a watershed, with streams crossing the ridges rather than flowing along the valley floor. --Dystopos 07:18, 29 August 2007 (PDT)
  • The first thing I looked at, back a couple of weeks ago when the thread was started on AL.com, was the online topo maps from the USGS, and they don't have anything at all resembling a river or even a creek that runs from Highland Ave northwesterly towards the 18th St N/5th Ave N intersection. I have no doubts that there are underground streams but if there was really a river it would be documented by now. Surely. --Wheresdib 07:26, 29 August 2007 (PDT)
  • Well, it's not the McWane Center, but next door at the Alabama Theatre the basement is so deep that they have to pump sewage up to the city sewer lines. It's only flooded once that I know of since 1985ish, and I think that was because said pump stopped working, not because of an underground river. --Lkseitz 13:31, 29 August 2007 (PDT)
