Michael,
I watched the video. It takes some courage to post this, because you open yourself up to criticism. I'm glad you were OK. What do you feel like you learned?
In my opinion, you didn't need a rescue (Monday morning quarterbacking). You weren't injured and you were using your tracking feature. Why didn't you just hike back the way you came? To your car.
"I'm feeling stuck" isn't a reason to not try. Fight your way back up the deep snow and push yourself. It seems like you were too quick to call for a rescue.
You had food, fuel (until you ran out) and your tracking. When you need a rescue is very subjective, but I don't think you tried hard enough.
What would have done if your Garmin died before you sent the SOS? Would you sit there and die? You'd probably try to get back to your car. Use the SOS when there are no other options for self-rescue, but before you're dead. :)
Edit: I was mistaken in thinking the OP was the person in the video. Thanks, Mark!
