Dispatches from the Cryosphere
For the majority of us in the Chesapeake Bay Watershed (with the exception of New Yorkers and those from northeastern PA), we will likely not encounter moraines, fjords, drumlins, eskers, or kettles on our watershed ramblings. These are just a few of the landscapes left behind by the massive Laurentide Ice Sheet that dredged its way across Canada and the northern tier of the U,S, 100,000 to 11,000 years ago.
However, there are still places on this remarkable planet that are covered with ice – the Cryosphere.
The Cryosphere is the part of Earth that is frozen. Think ice sheets, glaciers, permafrost. The “cry” in Cryosphere is derived from the Greek krios, meaning cold, but I can’t help think of the double meaning here as these fragile systems melt away.
