Strangest Bug I’ve EVER Seen!

I was camping up by Superior Wisconsin, and saw this bug sitting on a wood railing. It was huge! Probably from my knuckle to my wrist in length. It had really LONG antennae, and looked like some science experiment gone wrong. For the last year I’ve been trying to identify it, but have yet to. Hoping you can fill me in on what this fascinating and yet strangely odd bug is!

Longhorned Borer Beetle

Hi Melissa,
This beetle is one of the Longicorns or Longhorned Borer Beetles in the family Cerambycidae.  We believe it is a Flat Faced Longhorn in the subfamily Lamiinae and you may reference BugGuide to see some examples.  It might even be in the genus
Monochamus, however, the detail and angle of your photo makes positive identification difficult for us.
