The Laurentian Ice Sheet, where now lies the Hudson Bay, had glaciations named for each geographic region: Nebraskan, Kansan, Illinoisan, and Wisconsin. Markings of these glacial events can still be seen in parts of Minnesota today in the form of striations and grooves within the ground, the irregular hilly deposits from end moraine, the high terrace created by ancient rivers, exposed bedrock, and the finely textured silt of loess found in the prairie soils. It is the geographic history that helps create the beauty and unique lands within the state of Minnesota.

There are numerous types of seed dispersal methods within the plant kingdom. One such method is through a diaspore, a unit that consists of seed and additional tissue to help with dispersal. While these may be found with fruit, common in plants dispersed by frugivores, another commonly seen diaspore is known as foxtail, or spear grass. As the common name implies, it can be harmful, or even fatal, to livestock and pets due to its sharp structure. Foxtail itself refers to a number of grasses, some with a fanning structure and others with a cone shape. Control of foxtail is important in pastures.

Time to get back to posting! The next handful of posts will be things I ran across while in Minnesota. Unfortunately, though it is the Land of 10,000 lakes, my time there was limited almost exclusively to work, but I managed to gather a few nature-related photographs for sharing.
