The obvious north-facing gully off the Twin Lakes/Swamp Creek Road is quicker both up and down once the road melts out nearly that far. It's also skiable more or less to the car if you time it right. Plus it's way more scenic, and you'll have that whole side of both peaks of Goat Mountain to yourself.
Drawbacks: a short season, and a definite rockfall risk in the gully.
I assume that's what you mean by the logging road which crosses Swamp Creek. I believe that's not the only one. I've talked to someone who tried climbing via the much lower slide path which faces approximately west, not too far from the Mt. Baker Highway. They said it was arduous and not much fun. And I've wondered about some obvious approaches from above Twin Lakes itself, but by the time it becomes practical there are always more appealing tours to be had. But with sled access in winter, that would skip the gully and start higher.
Hope that's helpful....for someone.
