The hip-hop superstars weren't exactly trying to stay incognito -- once outside they removed their masks and sat on a bench for a bit talking.
Of course, these 2 go way back to their Roc-A-Fella Records days, and it seems Dame flew in to check on Ye ... on the heels of his Monday and Tuesday night Twitter attacks against his wife and mother-in-law.

Kanye is reportedly working on new music while he's in Wyoming, so it's possible Dame came by for that too -- but we know family and friends have been concerned about his mental health since the Sunday rally in South Carolina.

With Dave, and now Dame, jetting into Wyoming ... Kanye's friends are doing their best to rally around him.
