Abstract

Measured sections used in the preparation of facies and other regional maps are best located by section, township, and range. To examine the described section in the field, reference should be made to geographical landmarks, e.g., "measured along the E. bank of the N. fork of Ash Creek Canyon, 1 1/2 mi. E. of Johnson's Ranch." Adequate location of measured sections is essential for examination of the basic field data.
