Field Notes
Not many low branches are alive. Only the youngest tress had low enough branches to examine. The site was within eyesight of a road. The ground was very wet. We saw no trash. There was some scat (unidentified) next to tree #2.
Supporting Evidence
This picture shows that we were looking at hemlock trees. The needles are flat, have racing stripes on the underside, and are alternating.
Of the four trees we looked at, two trees had branches like this, with nothing unusual on the undersides of the branches.
This is typical of the undersides of the branches of all 4of the trees we examined. There are 2 places where there are dead needles clumped together, but no white fuzz.
The type of "fuzz" that we saw is shown in this picture. We saw this on branches of two of the 4 trees we examined. We did not see reddish eggs as shown in the species card, although we did see small back dots. What we saw was more weblike and stretched between several needles; what was shown on the cards was more clumped.

Comments
Good photos of the damage.
Good photos of the damage. The black specks are frass from needle-mining caterpillars. They also produce the silk. Their work makes a protected spot to feed and develop into moths. More info here: http://www.dec.ny.gov/docs/lands_forests_pdf/hemlockpests.pdf.
fuzz buster
I see racing stripes and petioles. You're definitely looking at the right tree. Your "fuzz" doesn't look like HWA to me either.
Your macrophotography skills
Your macrophotography skills are awesome! Did you think for a minute that the webbing that you show in your 3rd evidence photo might be hemlock woolly adelgid or were you totally sure it wasn't from the very first time you saw it?
Looks like a really nice place to explore. Nice work!
