Hornets Nest

From reading online, I think this is a baldfaced hornets nest?

It looked empty to me, but I sure wasn't going to get any closer to find out! Love my camera zoom.

Sounds like the nests are built in the spring and by autumn or after hard frost they are abandoned.

PDF says: nest made out of wood pulp, because the nest was in the tree it's probably a baldfaced hornets nest

Says not a true hornet genus but a yellowjacket?
Build nest in spring and by winter is abandoned and probably won't be reused.
Chew up wood that mixes with a starch in their saliva, which they spread with their mandibles and legs to dry into paper.
Has a pic of a dissected nest so you can see what the inside looks like.

unexco site
The paper-like covering of the nest is made from chewed up wood, cardboard or paper that the workers will form into the outside nest covering. Nests can also be colorful as wasps will gather nest materials from different sources.
