Photo Friday: Ice forms Lake Michigan stringers

By Evan KreagerGreat Lakes Echo Ice stringers, the lines of ice that can be seen traveling out across these Lake Michigan waters, are formed when strong winds blow ice off a point of land and into a long, connected string. This photograph produced by astronauts on the International Space Station shows Washington Island off the point of Wisconsin’s Door Peninsula and two smaller adjacent islands. They are joined by ice. When this photo was taken on Feb. 22, strong southwesterly winds blew against their ice-covered shores, according to NASA’s Earth Observatory.

Landscope: Increasing presence of well pads in Michigan

Take a look at this map. Cover the title, key and footer. It looks as if someone had a blank map of Michigan and began splattering paint across it. It’s like a work of art. But when the title of the map is revealed, it becomes obvious that all those pretty colors are actually different types of wells strewn across Michigan’s mitten.

Invasive Species: Round Goby

The Nature Conservancy has named the round goby one of the five “usual suspects” invading the Great Lakes basin. Round gobies are native to the Black and Caspian seas, but have found their way into the Mississippi River as well as Lake Michigan. These fish have a heightened ability to sense water movement, allowing them to feed in the dark. Round gobies feed on native fish and their eggs, and have a “blood vendetta” against zebra mussels, according The Nature Conservancy. These gobies can grow up to 10 inches in length and somewhat resemble an overgrown tadpole with black, gray or brown skin.

The Nature Conservancy has named Eurasian Ruffe, a fish native to northern Europe and Asia, as one of the five “usual suspects” in the Great Lakes basin. This fish has invaded northern Lake Michigan and feeds on native fish eggs. It has sharp spines on its fins making it difficult for predators to catch and eat, giving it the nickname, “Dagger Fin.”

Eurasian Ruffe are generally just under a half a foot in length and have an olive or golden-brown color.

Photo Friday: Pitcher’s thistle

By |

Here’s a reminder of Great Lakes beaches in warmer times. This plant is the federally and state-protected Pitcher’s thistle, which is also known as a dune thistle. The photo was taken last summer by habitat restoration specialist Terry Heatlie at Bois Blanc Island in north Lake Huron between Michigan’s Upper and Lower Peninsulas. The Pitcher’s thistle is native exclusively to the Great Lakes region, according to the National Fish and Wildlife Service. It was added to the government’s list of threatened species back in 1988.
