How Thick Is the Earth's Crust? ... We present a new contour map of the thickness of the Earth's crust. We use a 10 km contour interval plus the 45 km contour. This contour map was created directly from the 5 deg. by 5 deg. gridded crustal model CRUST 5.1 (Mooney et al., 1998) plus complementary information.
