Why and where I found it is when I was reading the Wikipedia article on the Alta Via del Sale, from where this picture is taken. It’s also one of the examples. It is on average rated SG 3-4 and piece-wise SG 4-5.

One other example, also ridden by us during the Alps Divide ULTRA was the Col de Sommeiler, which is rated SG 4 throughout.
