Photo Friday: Cold produces sundog above Lake Superior

By |

By Evan KreagerGreat Lakes Echo This image taken over Lake Superior’s southern shore shows a reflection of light known as a “sundog” on the outer edges of a halo surrounding the sun. Fog is created when cold air moves over water that is much warmer. Because of the cold, this fog often contains tiny ice crystals. The crystals can act as prisms, creating a 22-degree circle of light around the sun known as a “22-degree halo,” according to Earth Science Picture of the Day, which published this image. The picture was taken by Shawn Malone on Jan.

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.

Photo Friday: Land distribution around railroad supply town

By |

By Evan KreagerGreat Lakes EchoThe small town of Reese, just south of the crease of Michigan’s Thumb, was once a bustling supply center at the crossroads of two railways. This true-color image, taken by NASA’s Earth Observing — 1 satellite on May 21, 2012, shows the town at their intersection. The green and white square plots of land also gives insight into some of the area’s history, according to a description of the image produced by NASA. In the late 18th century, the Continental Congress decided how to govern the newly settled lands west of the Appalachian Mountains, according to the NASA description. The Ordinance of 1785 divided the land into townships, and then again into individual square mile plots, creating the colorful collage seen here.

Photo Friday: Ice atop Lake Erie

By |

When last week’s snowstorm and cold spell made its way through the Great Lakes, nearly 90 percent of Lake Erie froze over, according to the NASA Earth Observatory. The colorized picture above shows ice (pale blue) and snow (blue-green) formed on top of the lake. A report by Jeff Masters, director of meteorology at Wunderground.com, showed that these high levels of ice coverage had not been seen on the Great Lakes since January 1994.
