Thane H. McCulloh, Robert J. Fleck, Rodger E. Denison, Larry A. Beyer, Richard G. Stanley
2002, Professional Paper 1669
Volcanic rocks, mostly basalts and some andesites, are interbedded with middle Miocene strata and are overlain by younger rocks throughout the greater part of the Los Angeles Basin, California. Roughly correlative flows, previously dated radiometrically (or paleontologically) at about 16.4 to 10.7 Ma, crop out in five separate regions around...

Douglas A. Burns
2002, Water-Resources Investigations Report 2002-4066
The Rocky Mountain region of Colorado and southern Wyoming receives as much as 7 kilograms per hectare per year ((kg/ha)/yr) of atmospheric nitrogen (N) deposition, an amount that may have caused changes in aquatic and terrestrial life in otherwise pristine ecosystems. The Rocky Mountain National Park, in its role of...

Historical trend in ice thickness on the Piscataquis River in central Maine.
Thomas G. Huntington, Robert W. Dudley, Glenn A. Hodgkins
2002, Conference Paper, Proceedings of the 59th Eastern Snow Conference, June 5-7, 2002, Stowe, VT
We analyzed a long-term record of ice thickness on the Piscataquis River in central Maine to determine whether there were temporal trends that were associated with climate warming. Trends in ice thickness were compared and correlated with regional time series of winter air temperature, heating degree days (HDD) , date of river ice-out,...
