Yes, one and the same.  Redistributed with his permission.

Derrick, (while I'm sending you email), check this out:

The AskJeeves imagery at that resolution is the NYSGIS 60cm/pixel
infrared.  See the wye?  It's quite hard to see using visible imagery.
I've gone to the location, and there's definitely a wye there, but the
infrared makes it obvious.  I believe that the wye was used between
1851 and 1886, when the Potsdam & Watertown terminated there.
