Water chemistry of Oregon Cascade wilderness lakes : a comparison to 1985 data

Creator:: Logan, Michael Burke
Abstract:: The Western Lake Survey (WLS) of 1985 documented the status of lake water chemistry across the western US and inferred population representations of various subregions and geomorphic units via statistically analyses. Results from this 1985 study indicated that lakes of the Oregon Cascades had the second most pristine and dilute...

A paleomagnetic study of Recent Cascade lavas

Creator:: McKnight, William Ross
Abstract:: Ninety-five oriented samples were obtained from nine Recent Cascade lava flows in Oregon. Directions and intensities of remanent magnetization were measured on a spinner magnetometer which measures directions of magnetization to within 1.2° s.d. Angle measurements were plotted graphically using an equal area projection. Mean directions and statistics were calculated...
