These ants are approximately 4-5 cm in length (bigger than Formica fusca workers but smaller than Camponotus modoc workers), and were found at a high elevation (Simon Fraser University).

 

 

 

I suck at IDs, but my best guess is that they're Formica aserva?

Formica ravida like high elevations.

Sounds like either Formica gigantus or Formica astronomicus to me.

Trager mentioned: Yes, looks like Formica aserva. Your middle picture (the most useful one for ID) shows the general lack of pilosity and truncate clypeus typical of this species.

I'd say 5-6 mm, based on my experience with this ant. F. pacifica is in the 4-5 range.
