The moment we arrived at the falls of Girão we searched for stone carvings, finding a few, and several repetitions of circles similar to those already found. Designs a and d are on the west and east side of the same rock, which is 9 feet in length. The figure is 21 inches high, the five circles 1 foot across. The east side was almost obliterated. Designs b and c are on loose stones; b, facing west, is 16 inches long; the rock is 50 inches long and 35 wide; c is 22 inches long; the rock 70 inches long by 27 inches broad, and was 30 feet above the river at date. The rocks are basaltic, dipping north at an angle of 86°. Many small stones, 1 and 2 feet in diameter, lie about, with marks on them nearly defaced.

At Pederneira all the rocks on the right side at the foot of the rapids are literally covered with figures. Fig. 115 a is on a large bowlder facing the south; b has joined to its right side, c; d, e, and f are on the same stone. Most of these rocks are only a few feet above low water and are covered at least eight months each year.
