  • The Effect of the Shrinking Great Salt Lake on Snow Duration in The
    University of Utah UNDERGRADUATE RESEARCH JOURNAL Blowing in the wind: The effect of the shrinking Great Salt Lake on snow duration in the Wasatch Mountains. Chase Hodges-Heilmann (Gannet Hallar, Tanner Visnick, Christopher Rapp) Department of Atmospheric Science Introduction Utah has two things that tourists know about, the Great Salt Lake, and the Greatest Snow on Earth. The Great Salt Lake is receding and impacting the seasonal duration of the Greatest Snow on Earth. As the Great Salt Lake shrinks, the more arid surface contributes to more windblown dust. When this dust deposits onto snow, the albedo of the surface is decreased, and thus snow melts quicker. Relevant Literature Health complications, issues with visibility, and climate change are all influenced by windblown dust. Dust from the Great Salt Lake accounts for a total of 7% of all wind-blown dust in the Wasatch mountains (Skiles et al., 2018). Lake Sevier and the Great Salt Lake Desert make up the majority of wind-blown dust on the Wasatch mountains (Hahnenberger and Nicolli, 2012). Although dust from the Great Salt Lake right now isn’t major, the lakebed of the Great Salt Lake is becoming more and more exposed. Since pioneers arrived to Salt Lake City in 1847 the Great Salt Lake has decreased in elevation by 11 feet, which translates to a volume reduction of 48% and exposing nearly half of the lake bed (Wurtsbaugh et al., 2016). A decrease in volume of saline lakes is often attributed to global warming and climate change, but water development and diverting tributaries is also to blame (Wurtsbaugh et al., 2017).

  • South Dakota to Nebraska
    Geological Society of America Special Paper 325 1998 Lithostratigraphic revision and correlation of the lower part of the White River Group: South Dakota to Nebraska Dennis O. Terry, Jr. Department of Geology, University of Nebraska—Lincoln, Lincoln, Nebraska 68588-0340 ABSTRACT Lithologic correlations between type areas of the White River Group in Nebraska and South Dakota have resulted in a revised lithostratigraphy for the lower part of the White River Group. The following pedostratigraphic and lithostratigraphic units, from oldest to youngest, are newly recognized in northwestern Nebraska and can be correlated with units in the Big Badlands of South Dakota: the Yellow Mounds Pale- osol Equivalent, Interior and Weta Paleosol Equivalents, Chamberlain Pass Forma- tion, and Peanut Peak Member of the Chadron Formation. The term “Interior Paleosol Complex,” used for the brightly colored zone at the base of the White River Group in northwestern Nebraska, is abandoned in favor of a two-part division. The lower part is related to the Yellow Mounds Paleosol Series of South Dakota and rep- resents the pedogenically modified Cretaceous Pierre Shale. The upper part is com- posed of the unconformably overlying, pedogenically modified overbank mudstone facies of the Chamberlain Pass Formation (which contains the Interior and Weta Paleosol Series in South Dakota). Greenish-white channel sandstones at the base of the Chadron Formation in Nebraska (previously correlated to the Ahearn Member of the Chadron Formation in South Dakota) herein are correlated to the channel sand- stone facies of the Chamberlain Pass Formation in South Dakota. The Chamberlain Pass Formation is unconformably overlain by the Chadron Formation in South Dakota and Nebraska.

Data from marine sediments suggest that deposits from two asteroid impacts (one close, one far away) may be preserved in the Badlands. These impact- generated deposits may represent late Maestrichtian events or possibly the terminal K-T event. Interpretation is supported by paleontological correlation, sequence stratigraphy, magnetostratigraphy, and strontium isotope geochronology. This research is founded on nearly a decade of NPS approved field work in Badlands National Park and a foundation of previously published data and interpretations. The K-T boundary occurs within
