My dodgy generalisation is that the US resorts probably have shorter runs,
lower vertical drops but at least do have more of the white stuff which is
always useful if you want to slide down it.


Alps were glaciated. Rockies were not. Gives different terrain. The
slopes of the Rockies are wider, hence US skiers express surprise at
the number of catwalks in European resorts (which are bulldozed into
the mountain to enable easy transit).
