We report new results on v{sub 2}(p{sub T}) for Au+Au collisions at {radical}(S{sub NN}) = 200 GeV for charged hadrons, pions, kaons,(anti)protons, K{sub s}{sup 0}, and Lambda. The analysis is extended to p{sub T} = 12 GeV/c for charged hadrons and p{sub T} = 4 GeV/c for identified particles. A comparison of the azimuthal anisotropy of charged hadrons measured at sqrt {radical}(s{sub NN}) = 130 and 200 GeV is presented. The p{sub T}-dependence of baryon versus meson elliptic flow is discussed.

The authors discuss some of the results on the measurements of heavy flavor production at the Tevatron. Heavy flavor production can be used to test QCD over a wide range of quark masses (m{sub b} {approx} 4.5 GeV/c{sup 2} to m{sub t} = 174.3 {+-} 5.1 GeV/c{sup 2}). In addition, it is a background that has to be understood to perform physics measurements in the top sector and Higgs searches. The results reported here are performed using the Run1 data collected at Tevatron ({approx} 100 pb{sup -1}).

Clay-poor lahars of late Holocene age from Mount Rainier change down the White River drainage into lahar-derived fluvial and deltaic deposits that filled an arm of Puget Sound between the sites of Auburn and Seattle, 110-150 km downvalley from the volcano's summit. Lahars in the debris-flow phase left cobbly and bouldery deposits on the walls of valleys within 70 km of the summit. At distances of 80-110 km, transitional (hyperconcentrated) flows deposited pebbles and sand that coat terraces in a gorge incised into glacial drift and the mid-Holocene Osceola Mudflow. On the broad, level floor of the Kent valley at 110-130 km, lahars in the runout or streamflow phase deposited mostly sand-size particles that locally include the trunks of trees probably entrained by the flows. Beyond 130 km, in the Duwamish valley of Tukwila and Seattle, laminated andesitic sand derived from Mount Rainier built a delta northward across the Seattle fault. This distal facies, warped during an earthquake in A.D. 900-930, rests on estuarine mud at depths as great as 20 m. The deltaic filling occurred in episodes that appear to overlap in time with the lahars. As judged from radiocarbon ages of twigs and logs, at least three episodes …
