THE FIRST RESPONSIBILITY -

- - OF A PROFESSIONAL GROUP IS TO PROVIDE SUBSTANTIALCONTRIBUTIONS TO ITS FIELD THAT WOULD NOT OTHERWISEMATERIALIZE. FURTHER, IT IS THE PERSONAL RESPONSI-BILITY OF EACH MEMBER TO CONTRIBUTE A SHARE OF THEEFFORT REQUIRED BY PROJECTS SPONSORED BY HIS GROUP.ADDED ABILITY WITH WHICH TO SERVE HIS PARTICULARROLE, WHETHER IT BE THAT OF A CONSULTANT, A TEACHER,OR EMPLOYEE, IS HIS REWARD.

THIS NINTH ANNUAL FIELD CONFERENCE AND THE FOLLOWINGPAGES COMPRISE A RECORD OF RESPONSE TO THESE OBLIGA-TIONS, AND PERPETUATE A FOREMOST PURPOSE OF THE NEWMEXICO GEOLOGICAL SOCIETY.

WHILE ENJOYING THE BROAD SCOPE OF THIS EXCURSION,CONSULT THE LIST OF COMMITTEE MEMBERS AND OFFER AGRATEFUL HAND TO THE DEDICATED INDIVIDUALS WHO HAVEGIVEN FREELY OF THEIR KNOWLEDGE AND TIME TOWARD THEPREPARATION OF THE CONFERENCE AND GUIDEBOOK.

DURING MANY MONTHS OF PLANNING, THE SPLENDID COOPER-ATIVE SPIRIT OF THE ARIZONA GEOLOGICAL SOCIETY DEMON-STRATES THE ADVANTAGES OF JOINT EFFORT IN BEHALF OF ACOMMON PURPOSE. AN EFFECTIVE PATTERN FOR THE FUTUREIS SUGGESTED.

MEMBERS OF THE EXECUTIVE COMMITTEE JOIN TO WELCOMEEACH OF YOU AND URGE YOU TO AVAIL YOURSELVES OF THELASTING FELLOWSHIP AFFORDED BY OUR MUTUAL PROFESSIONALINTERESTS. YOU ARE INVITED TO RETURN TO OUR TENTHANNUAL FIELD CONFERENCE IN 1959.WE OFFER ENTHUSIASTIC THANKS TO THOSE WHOSE CONTRIBU-TIONS HAVE ASSURED THE SUCCESS OF THIS VENTURE. OURGENERAL CHAIRMAN, RICHARD D. HOLT, HUMBLE OIL REFIN-ING COMPANY, ROSWELL OFFICE, MERITS SPECIAL RECOGNI-TION. To HIM, I EXTEND MY PERSONAL AND SINCERE GRATI-TUDE.

REX ALCORN, PRESIDENTNEW MEXICO GEOLOGICAL SOCIETY

ACKNOWLEDGMENTS

Primary acknowledgment is due the Arizona Geological Society, whose cooperation makes this con-ference possible. As a group, and as individuals, as committee members, editors, authors of indi v i d u a 1papers, and solicitors of the works of their confreres, they have carried a major part of the preparation of theguidebook and of the field conference. They are showing us the hospitality of our neighbor State, as wellas the intensely interesting geology of a very beautiful portion of it.

The New Mexico Geological Society is grateful to all the Conference Committee members, and tothe individuals, organizations, companies, and advertisers whose cooperation with them have made t h eguidebook and the conference technically and physically possible. Special mention is due the United StatesGeological Survey for authors, editors, and committee men. Also the University of New Mexico, the Uni-versity of Arizona, the New Mexico Bureau of Mines & Mineral Resources, the New Mexico Institute ofMining & Technology, the Atomic Energy Commission, several oil companies, and individual consultants,some identified in author or committee listings, but many sharing the effort unnamed.

The general chairman wishes to express his thanks and gratitude - and even awe and amazement -for the cheerful and enthusiastic manner in which all of these assignments and solicitations were accepted,and the keen and efficient manner in which they were carried out. Let the obvious appreciation of thosein attendance at the conference, and of the many proud owners of the guidebook, be their fitting reward.

The Society wishes to thank the National Park Service for cooperation at Petrified Forest, SunsetCrater, Wupatki, and Grand Canyon. Grateful thanks are offered to the Northern Arizona Society o fScience and Art and to Lowell Observatory for having the museum, the research center, and the observa-tory accessible to us during our stop in Flagstaff.
