The Geological Survey in 1928, 1929, 1930, and 1931 reexamined and mapped the coal beds of the Mesaverde formation across the southern part of the San Juan Basin, in New Mexico, from Gallup on the west to Cuba, Grant, and the Rio Puerco on the east and southeast. The geologists have prepared separate reports on the areas for which they were responsible.

No edition of the consolidated volume will be published, but the three parts can be bound together if desired, ii CONTENTS
