> Skiers are not much better at judging angles, as it usually feel steeper than it actually is! That said, Way Up is quite mellow for a Grade I, despite being narrow. My guess is there's nothing over 45 degrees (I've skied it twice).
I would say that's right. I've been up and down it many times, bum slid, walked nervously when icy. There's a section quite high up which is 45 degrees and narrower (but obviously OK for skiing) while the rest is easier. No steps in summer.
