213 Winter 1949 Fig. 12. The Markings of Palpa. This composite aerial photograph gives a good over-all view of the maze of lines, "roads," triangles, and trapezoids on a plateau just about the valley and town of Palpa. This valley is just to the north of the valleys of Nazca and Ingenio and is part of the Rio Grande System. (Servicio photos.) Nacional Aerofotografico This drawing Fig. 13. Gat-Demon. near Palpa seen on this aerial photograph appears to be similar to those found on textiles and water jugs of this region and is generally known as the "cat-demon," and is probably derived from the mountain "tigers" found in Peru. It may have been associated with the paths and the triangle seen below it.
