NASA-SP 370. 2 volumes (929 pages), well illustrated, charts, diagrams, tables, cloth, very good. 8 by 10-1/2 inches. 'Finally, there is a NASA report titled, The Soviet-American Conference on Cosmochemistry of the Moon and Planets. This report is a source which, in this author's opinion, contains everything anyone ever wanted to know about meteoric influx and the depth of moon dust. As this report explains on page 574, the moon's "maria" (the darker, more recently melted areas) have dust piled several meters thick over them; but that its "continental regions" are piled as deeply as dozens of meters thick 14 - this would be about 100 feet.'
