Overview

Excerpt from Rock Art in the Navajo Reservoir District High, inaccessible panels and those with little level foreground had to be photo graphed at an angle, thus distorting the figures to some degree. For this reason all accessible panels were drawn as well as photographed. In order to record large panels of petroglyphs in their totality, a string grid of foot squares were set up as a guide for drawing on graph paper. As an aid to copying, many of the petro glyphs were chalked in outline before drawing. In this way, Shapes were more accurately determined in vague cases and the small details were brought to the attention of the recorder. It was more expedient and accu rate to make tracings with crayons on plastic sheets taped to the cliff over iso lated or very small groups of figures and the many-colored and complex rock paintings. Colors Of the paintings were matched in the field with pastels. In addition to the drawings, field notes were taken on technique, weathering and patination, site situation, and other pertinent factors. Samples of the pigments of the paintings were obtained and brought back to the laboratory for analysis. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
