Magnitudes and implications of peak discharges from glacial Lake Missoula
New field evidence and discharge calculation procedures provide new estimates of maximum late Pleistocene glacial Lake Missoula flood discharges for two important reaches along the flood route. Within the Spokane Valley, near the point of release, the peak discharge probably exceeded 17 ± 3 million m-sec. Downstream at Wallula Gap, a major point of flow convergence, peak discharge was about 10 ...
متن کاملThe sequence and timing of large late Pleistocene floods from glacial Lake Missoula
Glacial Lake Missoula formed when the Purcell Trench lobe of the Cordilleran ice sheet dammed Clark Fork River in Montana during the Fraser Glaciation (marine oxygen isotope stage 2). Over a period of several thousand years, the lake repeatedly filled and drained through its ice dam, and floodwaters coursed across the landscape in eastern Washington. In this paper, we describe the stratigraphy ...
متن کاملReconstruction the climatic changes of the last 600 years in Southeast Iran, study area, the Lake Sardarya, Taftan Volcano
Introduction: In order to recognize the mechanism of local climatic settings and to be able to establish the future climatic scenarios is essential to understand the past climatic and environmental conditions of the each area. This is also important to explore the response of local areas to the global climatic variations. The palaeoclimate researches carried out in Iran mainly considered the g...
متن کاملSedimentological evidence of the level and climate changes of Lake Zeribar in the Holocene
Lakes are very interesting sedimentary environments for the study of ancient climate, changes in sedimentary environments and lake level changes. Lake Zeribar is situated in the Zagros Mountains, Kurdistan, Iran. The main purpose of this research is to examine grain size sediments, geochronology and clay mineralogy accumulated in Zeribar Lake in order to check the water level fluctuations, clim...
متن کاملChronology of latest Pleistocene lake-level fluctuations in the pluvial Lake Chewaucan basin, Oregon, USA
New accelerator mass spectrometer radiocarbon ages from gastropods in shore deposits within the pluvial Lake Chewaucan basin, combined with stratigraphical and geomorphological evidence, identify an abrupt rise and fall of lake level at ca. 12 14C ka. The lake-level high is coeval with lake-level lows in the well-dated records of palaeolakes Bonneville and Lahontan, and with a period of relativ...
