Abstract: Eruptions and other geologic events at Mount Baker during the last 10,000 years have repeatedly affected adjacent areas, especially the valleys that head on the south and east sides of the volcano. Small volumes of tephra were erupted at least four times during the past 10,000 years. Future eruptions like these could cause as much as 35 centimeters of tephra to be deposited at sites 17 kilometers from the volcano, 15 centimeters of tephra to be deposited 29 kilometers from the volcano, and 5 centimeters, 44 kilometers from the volcano. Lava flows were erupted at least twice during the last 10,000 years and moved down two valleys. Future lava flows will not directly endanger people because lava typically moves so slowly that escape is possible. Hot pyroclastic flows evidently occurred during only one period and were confined to the Boulder Creek valley. Such flows can move at speeds of as much as 150 kilometers per hour and can bury valley floors under tens of meters of hot rock debris for at least 15 kilometers from the volcano. Large mudflows, most of which contain hydrothermally altered rock debris, originated at Mount Baker at least eight times during the last 10,000 …

From summary: The purpose of this study was to delineate favorable areas for uranium resources in northeastern Washington and northern Idaho by identifying granitic rocks with relatively large amounts of uranium and (or) thorium. Results are based on analyses of 344 rock samples; 230 were collected during this study, and data for the rest were taken from previous publications.

Appendix containing river sediment data graphs in addition to chemical and physical analysis data to accompany a report on aquatic disposal field investigations of the Duwamish Waterway disposal site in Washington.

Appendix containing data on the recolonization of benthic macrofauna over a deep-water disposal site in the Duwamish River influenced portion of Elliott Bay. It accompanies a report on the chemical and physical effects of open-water disposal of dredged material from the Duwamish River into Elliot Bay as part of a study to determine the effects of disposal sites on organisms and the quality of surrounding water.

This appendix includes data documentation from the analysis of water, sediment, SPM, elutriates, and interstitial waters for chlorinated biphenyls, and the results from this analysis of sediment for TOC, oil-grease, and percent-solids.

Appendix presenting data listings and depth profiles of hydrography reports recorded as part of a study evaluating the release of polychlorinated biphenyls during open-water disposal of contaminated dredged material in Elliot Bay, Puget Sound, Washington.
