Urus Central and Urus Oeste

... from Urus Este. The sign down in the valley that points to the trail to Urus Este is misleading, as it says 5495m. However, it's Urus Central that is 5495m, followed by Oeste with 5450m and then Este with 5420m. Still, everybody climbs Este. I asked around why that was. Most people didn't really seem to know or even care, but a few said that Central was more difficult. So I asked, how much more? But nobody could tell me. 28 June 2011.
