Check out insane photos of Highmark Stadium taken on Friday morning -- showing the field, seats and just about everything else at the venue covered in several FEET of snow.

In the pics, you can't even get a glimpse of green grass -- let alone the chairs where Bills supporters were supposed to sit for Sunday afternoon's contest.

According to weather reports, Orchard Park has been hit with 36 inches of snow in the past few hours ... and it's expected to get pelted with a bunch more in the near future as a massive storm continues to pound the Western New York area.

Things have gotten so bad, the Bills had to cancel their Friday practice over it all.

Meanwhile, at star quarterback Josh Allen's home near the stadium -- his doggo and girlfriend are struggling with the effects of the storm too.

Brittany Williams posted pics of her falling in the powder while trying to get the couple's pup to go to the bathroom.

As for the game on Sunday, it's been moved to Detroit -- with the NFL saying Thursday the conditions just weren't safe enough for all involved to play.
