I don't have a video, or anything, but there's another shortcut. It doesn't require buying a horse for the 4x4 stickyhoof glitch, anyone can do it on foot, with relatively little trouble. Just fast travel back to Helgen, you'll come out at the East gate, and head East toward the Rift Stormcloak Camp. Hang a left before the signpost, there's several little hollers there, so if you get to that landmark, turn back, and go up the one before it. Then past Orphan Rock, to South Skybound Pass. Don't bother going in, that takes you back down toward Riverwood, and a Wispmother.
Turn left, and you will see 2 slopes on either side of ridge. Take the one strewn with boulders, it won't get you all the way, but when you can's climb any higher, stickyfoot around the ridge to the snowy one. Stick to the middle, where it's not too steep to climb without jumping, and just run up the slope to the path. You'll come out just past the Beefgate Frost Troll, and avoid all the animals on the path. Go say hi to Arngier for me.
