The Hills have lots. Limestone is one of our most abundant resources. Most of it is the typical yellow stuff, with many small pockets, butter-dish edges and thin cracks.
There is some black rock mixed in. Much of it is moderately overhanging, with a few roofs, often close to the ground.
There is also a bit of sandstone. Nothing like the acres of patina found in the South, but of good quality.
For sport climbers and boulderers, there are worse places to be. Still, the magma-forged stone is the main attraction.
