Abilene we head south on route 84 to our first stop which is just south of Jim Ned Creek were we see Permian sedimentary rocks. We visit these so we can compare them with the much older rocks visited in the Hill Country. Our next stop is on highway 87 just south of the San Saba River. The following stop is north of Valley Spring on route 71. At the latter two stops we see Cambrian sedimentary rocks. Our next stop is near Inks Lake. Then we go to the town of Llano just below the bridge over the llano River.
