Pictured Rocks is the site of many of Michigan's waterfalls. Most of the waterfalls resulted from water running over the cliffs of the Munising Formation. This lime and sandstone formation exists between Tahquamenon Falls , some 75 miles (121 km) east, to Laughing Whitefish Falls , 30 miles (48 km) west of the Lakeshore.
Jacobsville Sandstone is a red sandstone formation, marked with light-colored streaks and spots, primarily found in northern Upper Michigan, portions of Ontario, and under much of Lake Superior. Desired for its durability and aesthetics, the sandstone was used as an architectural building stone in both Canada and the United States.
The pale yellow portion shows the Upper Peninsula (UP) of Michigan. Marquette is on the south shore of Lake Superior, straight north of the "'r' in the word 'Upper'". Recent geologic mapping in the Marquette, Michigan, U.S., area provides information of the structure for the zone along a 10 km (6.2 mi) strike.
The Michigan Basin is a geologic basin centered on the Lower Peninsula of the U.S. state of Michigan. The feature is represented by a nearly circular pattern of geologic sedimentary strata in the area with a nearly uniform structural dip toward the center of the peninsula.
A survey of Lake Michigan located at least 40 large craters on the lakebed. Initial studies highlighted the spots as unknown shapes, but additional research revealed the craters are filled with ...
The Lake Border Moraine (also called the Lake Border Morainic System) is a complex group of moraines bordering the southern end of Lake Michigan. It can be traced north along the eastern shore of the lake basin and across the highlands between the northern Lake Michigan and Saginaw Bay .
Structural dome on Baffin Island, seen in a planation surface. Oblique aerial photo of Upheaval Dome, Utah. Now considered to be a deeply-eroded impact crater, it was for many years believed to be a salt dome. Caprock of a salt diapir at Cape Breton, Nova Scotia. The white rocks at left center are the gypsum and anhydrite carapace of the diapir.
The margins of the Canadian Shield have been covered by sedimentary rocks, such as in Michigan where a series of sediments has filled in the Michigan Basin. [4] The exposed sections are often where glaciers have removed this overlying regolith to reveal the underlying glacially scarred crystalline rock. [6]
