Wood Wasp

Dear Cory,
This is one of the Horntails or Wood Wasps in the family Siricidae.  They have larvae that are wood borers.  Your particular Wood Wasp is Urocerus flavicornis, a species that uses conifers as the host.  According to BugGuide its range is:  “all forested regions of Canada and the US.”
