Why are there so many granite erratics?

This is the Gray Bull in Wet Sleddale - it is the largest of the Shap granite erratics around but there are a lot of them, deposited by glaciers during the last Ice Age. I always notice erratics more in the Shap area and am wondering why. Is it that this granite is more prone to being carried by glaciers? Is it that this beautiful stone is so obvious that I notice them more? Or is it that this area is rolling wet moorland with few crags? It hasn't been improved much as farmland. I'm guessing it must be a combination of the second and third reasons.
