The Vermilion District in northeastern Minnesota contains one of the classic Neoarchean Archean granite-greenstone belt terranes in the United States that formed between 2722 Ma to ~2661 Ma. Crustal development during ...

To garner a better understanding of groundwater flow and water quality on the University of Wisconsin –Eau Claire campus, we collected monthly measurements in fourteen (14) monitoring wells across lower campus, including ...

Phosphorus (P)-laden runoff has been associated with lake eutrophication throughout the upper Midwest United States. Although P has been considered immobile in groundwater systems, investigation at UW-Eau Claire suggests ...

Gemmy hydrothermal quartz crystals typically exhibit each of their six prism and six rhombohedral crystal faces. However, discerning which of the crystal faces were actively growing at any given time during construction ...

Lower Paleozoic clastic strata of western Wisconsin were deposited during a series of transgressive marine incursions into the mid-continent in Cambrian to Ordovician time. These strata consist of intercalated sandstone, ...

Mud Lake experiences severe lake eutrophication throughout the summer months. Although anthropogenic nutrient sources have been identified as a contributing factor, an ongoing investigation at UW-Eau Claire has demonstrated ...

This study seeks to measure baseflow conditions in West-Central Wisconsin to aid in determining the impacts of groundwater withdrawals on local streams. Streamflow is measured monthly at fifteen (15) sites across eleven ...

The rocks containing the Crandon deposit are part of the Pembine-Wausau Terrain and formed ~1.85 billion years ago. These formed in a bark-arc setting as part of the Penokean Orogeny. Arc-derived sediments eventually covered ...

Lake eutrophication due to nutrient loading from phosphorus (P) is a growing problem across the Midwest, causing a loss of aquatic biodiversity, damage to fisheries, and adverse impacts on human health. Although eutrophication ...

An important skill in geology is the ability to visualize spatial relationships of geologic units beneath the Earth. Virtual and physical models allow students to observe and measure geologic structures and visualize their ...
