Mass balance and climate variables are reported for South Cascade Glacier, Washington, for the years 1986-91. These variables include air temperature, precipitation, water runoff, snow accumulation, snow and ice melt terminus position, surface level, and ice speed. Data are reduced to daily and monthly values where appropriate. The glacier-averaged values...
U.S. talc; baby powder and much more
Water Resources Division, U.S. Geological Survey
2000, Fact Sheet 065-00
When most people think of talc, they probably envision talcum and baby powder. Since talc is very soft and easily carved, one might also think of sculptures in soapstone (massive talc). In fact, these uses of talc are quite minor compared to its wide variety of applications in manufacturing and...
Water-quality data for streams in the Boulder River Watershed, Jefferson County, Montana
David A. Nimick, Thomas E. Cleasby
2000, Open-File Report 2000-99
Chemical data were collected in the Boulder River watershed of southwestern Montana during 1996-99 as part of a detailed interdisciplinary study characterizing the effects of historical inactive mines on streams in the watershed. This report presents water-quality data collected by the U.S. Geological Survey for physical properties, major ions, nutrients,...
Magnetic susceptibilities of minerals
Sam Rosenblum, I. K. Brownfield
2000, Open-File Report 99-529
Magnetic separation of minerals is a topic that is seldom reported in the literature for two reasons. First, separation data generally are byproducts of other projects; and second, this study requires a large amount of patience and is unusually tedious. Indeed, we suspect that most minerals probably are never investigated...

Water-level data for the Albuquerque Basin and adjacent areas, central New Mexico, period of record through 1999
Dale R. Rankin
2000, Open-File Report 2000-231
The Albuquerque Basin, located in central New Mexico, is about 100 miles long and 25 to 40 miles wide. The basin is defined as the extent of consolidated and unconsolidated deposits of Tertiary and Quaternary age that encompass the structural Rio Grande Rift within the basin. Drinking-water supplies throughout the...
Surveys of water velocities in the vicinity of the discharge-release gates of Salamonie Lake Dam, northeastern Indiana, spring and winter 1998
Scott E. Morlock, James A. Stewart
2000, Open-File Report 99-228
Two water-velocity surveys in the vicinity of the discharge-release gates were performed at the Salamonie Lake flood-control reservoir in northeastern Indiana during periods of high-discharge release. One survey was done in the spring when the reservoir pool was at high elevation; the other survey was in the winter when the...

Publications of the Western Earth Surface Processes Team, 1999
Paul Stone, Charles L. Powell II
2000, Open-File Report 2000-215
The Western Earth Surfaces Processes Team (WESPT) of the U.S. Geological Survey, Geologic Division (USGS, GD), conducts geologic mapping and related topical earth- science studies in the western United States. This work is focused on areas where modern geologic maps and associated earth-science data are needed to address key societal...
Geohydrology and numerical simulation of groundwater flow in the central Virgin River Basin of Iron and Washington Counties, Utah
V.M. Heilweil, G. W. Freethey, C.D. Wilkowske, Bernard J. Stolp, Dale E. Wilberg
2000, Technical Publication 116
Because rapid growth of communities in Washington and Iron Counties, Utah, is expected to cause an increase in the future demand for water resources, a hydrologic investigation was done to better understand ground-water resources within the central Virgin River basin. This study focused on two of the principal ground-water reservoirs...

2000, IMAP 2750-A
Over the past 30 years, communities in the Northern Front Range of Colorado have experienced tremendous growth rivaling or surpassing that in other parts of the United States. This growth has challenged businesses as well as city, county, State, and Federal planners to meet the increasing demands for natural resources...

Many landslides occurred on the coastal bluffs between Seattle and Everett, Washington during the winters of 1996 and 1997. Shallow earth slides and debris flows were the most common, but a few deep-seated rotational earth slides also occurred. The landslides caused significant property damage and interfered with rail traffic; future...
