Getting to the Top of the Mountain

Parkour is a climbing check for these kind of things if you wanted to try and push up. It's all said snow and ice covered rocks. Sometimes the haggle works in your favor, sometimes it doesn't. In an attempt to get to the top of the mountain without losing movement,. You rush up and as you're part way up, you barely see above the edge where your friends are. Your foot hits one edge where your momentum's been building and your foot hits smooth ice. Goes out, you watch her like bob up and then tumble back down. Oh, my gosh. On dead yelly.
