MP 15-2DM, Hogup Bar Quadrangle, Box Elder

By: Daren T. Nelson and Paul W. Jewell

The Hogup Bar quadrangle is located southeast of Park Valley, Utah, and west of the northwest arm of Great Salt Lake. Late Pleistocene Lake Bonneville sediments and related shorelines dominate the landscape, and record the transgression and regression of Lake Bonneville. Surficial deposits overlie Tertiary basalt and Permian-Pennsylvanian sedimentary bedrock.


Great Salt Lake may ebb and flow, however its current low levels give impetus to talk about water use, and how to use it more wisely in the desert. Andrew Rupke, a minerals specialist here at UGS, joins the conversation in this article. Check it out!


Not many states have a defining natural feature that locals actually discourage visitors from seeing.


While the weather has been warm, and there’s not a lot of snow or ice around, it’s a great time of year to look at the Ice Age animals of Utah. Did you know that Great Salt Lake is the remnant of Ice Age lake, Lake Bonneville? Read more about this different age in Utah in our “Popular Geology” subjects HERE.


Utah’s Great Salt Lake has been protecting the Wasatch Front from a potential health hazard for 150 years, but that protection is threatened, say some scientists, by a growing, thirsty population and a drying climate.
