Sandstone: Rock for Crack Climbing. Sandstone is a sedimentary rock, a rock type that encompasses a wide variety of characteristics and is deposited directly on the earthâs surface. Roughly 75% of the earthâs land surface is covered with some type of sedimentary rock. Sedimentary rocks like sandstone form when minute rock particles, often from granite, are deposited by wind and water on earth surfaces.

Sometimes tingling in legs will become extreme when walking. Extremities seem to fall asleep (different than the above numbness) often. A couple of months ago my foot (I believe left one only) several times fell asleep with a distinct centralized ball of heaviness/pain for lack of a better description.
