Geology of Sandhill Wildlife Area

Sandhill Wildlife Area was named for both the Sandhill cranes that frequent area marshes and for Grange's Sandhill Game Farm. Sandhill lies within the bed of Glacial Lake Wisconsin. This lake covered parts of Wood and six neighboring counties and was formed by the yearly run-off of melt water from the great Continental glaciers that covered much of eastern and northern Wisconsin from 60,000 to 10,000 years ago. With the retreat and disappearance of the glaciers, the lake drained, leaving a vast expanse of sandy soils covered by marshes and forests on the slightly higher, undulating sand ridges. Outliers or "mounds" that are remnants of a sandstone plateau deposited on the floor of seas that covered central North America 500 million years ago are also scattered throughout the region. North Bluff, which rises 200 feet above the surrounding plain, is composed of very ancient Precambrian quartzite rock that was sealed in sandstone for hundreds of millions of years.
