Dykeman Roebuck is involved in the final write-ups of the following Williams Trunk S archaeological excavations in Dinetah:


Site LA72759 is an archaeological site of a pre-ceramic society living in the uplands of the San Juan Basin. The excavation uncovered the remains of seven pit structure habitations, two middens and several hearths and other thermal features scattered along a series of very shallow washes on top of Pump Mesa, near the rim of La Manga Canyon in the upper San Juan River basin in Northwestern New Mexico. Radiocarbon testing of several samples from the site provide a calculated date range of 760 B.C. to A.D. 260. These results place the site in the transition period from late Archaic to Basketmaker II. Corn kernels, cupules and pollen were found at several locations throughout the site. Processing of corn, cactus and other floral products was a major focus of the activities at this site. An essential part of site LA72759's function may have been its geographical location and its relation to neighboring archaeological sites and ecological environments. This analysis examines a number of factors in assessing this site's situation.

The excavation of the site was undertaken by Cultural Resource Management Consultants, Inc., in conjunction with the Navajo Nation Archaeology Department, in the spring and summer of 1997. It was performed on behalf of Williams Field Services, Inc., in the on-going efforts to mitigate some of the adverse impacts of the Fruitland Coal Gas gathering system development associated with Williams' Trunk S pipeline construction.

This site was selected for data recovery activities according to the guidelines defined by the Memorandum of Agreement between the Bureau of Land Management, Farmington Resource Area, and the New Mexico State Historic Preservation Division for the Fruitland Coal Gas Archaeological Data Recovery.

Data recovery procedures were in accordance with the Data Comparability Guidelines for the Fruitland Coal Gas Gathering System Plan (FRACAG 1991), the Fruitland Data Recovery Research Design (Hogan, Elyea and Eschman 1991), and the Data Recovery Plan for Three Sites, including LA72759 (Dykeman and Wharton 1996). Excavation procedures and methods were defined by an in-house set of guidelines for CRMC (Dice 1999).

Cultural Resources Management Consultants, Inc., ceased doing business before the report of the excavation could be produced. Through the intercession of the Bureau of Land Management and the cooperation of Williams Field services, this volume, reporting those excavations, has been produced through the efforts of Kristin Langenfeld of Scalable Editing Services and Paul Roebuck of Dykeman Roebuck Archaeology.

This report details the excavations and provides a discussion of research questions.
