supported the study. Elizabeth Nystrom assisted with sampling and sampling equipment in the field, including the field measurement of methane. Richard Reynolds and Carolyn Van Alstyne also assisted with field sampling, and Patrick Phillips prepared statistical and quality-assurance analyses. Martyn Smith and Douglas Freehafer provided geographic information system support that included processing of lidar imagery, and generation and processing of stream network and topographic information that facilitated the definition of valley areas.

Les Arihood, Scientist Emeritus, U.S. Geological Survey (USGS), for his assistance in interpreting water-well drillers' records for the lithologic database and Sue Kahle, USGS hydrologist, for her contribution to the discussion of glacial geology in the northwestern United States. Finally, we thank Tom Nolan, USGS hydrologist, for his application of the dendrogram analysis in the comparison of sediment and aquifer characteristics of hydrogeologic terranes.

This report presents borehole geophysical logs from 21 wells completed in bedrock near the village of Windham, N.Y. The data were collected as part of a water-resources investigation conducted by the U.S. Geological Survey, during 1990-93, in cooperation with the New York City Department of Environmental Protection. Natural gamma logs, caliper logs, and fluid-conductivity and temperature logs are depicted for each well; driller's logs are included where available. Location maps and a table of selected well data are included. The geophysical logs provide indications of rock type and occurrence of water-bearing fractures.
