Came around the corner fast, Sadie just ahead of me, and Momma Moose and Baby Moose were standing no more than 20 ft off the trail in a clearing. 20 ft is very close in wild moose proximity terms. Some moose don't like runners (read Karl Meltzer's moose encounter) and Momma Moose generally doesn't like runners when Baby Moose is around.
So after a mild heartbeat skip and a fast sprint by I got far enough away to feel comfortable to take a photo. Sadie's curiosity got the best of her and she went toward Momma Moose (Baby Moose had climbed up well behind her) and got to about 10 yards away before Momma Moose let out a deep growl/puff that sent Sadie scurrying back to me.

I've heard some bad Moose attack stories and it's always in the back of my mind when I'm running around blind corners or switchbacks. This was my closest encounter yet, and I feel lucky that Momma Moose wasn't in an ill mood.
Sadie blew off the encounter and when we reached the top of our run she reasserted her dominance over the mountain with a majestic pose:
