Dear Jamie,
This is an American Dagger Moth Caterpillar,
Acronicta americana, and we found a matching image on BugGuide to verify its identity.  According to BugGuide:  “Larvae feed on leaves of alder, ash, birch, elm, hickory, maple, oak, poplar, walnut, willow and other deciduous trees” and “The caterpillar’s hairs can cause skin irritation.”
