A week of solitary work on North Manitou Island wraps up. A storm delays the boat, so it continues for now. Damp, thundershaken, sipping tea.

🌇 Guten Morgen Chicago 🌇
Another beautiful sunrise from the shores of Lake Michigan, which seems more like one of the Great Inland Seas. Every morning, watching these sunrises the likes of which I've not seen since childhood on the Eastern Seaboard, feels like being at the Atlantic ocean.
How about some science curiosity...
> During the middle Pleistocene era, the area now submerged under the Great Lakes had been a lowland river system. As glaciers advanced and retreated they carved these areas into the Great Lakes and filled them as they melted.
> The preservation of fossils in Michigan resumed when the last glaciers withdrew from the state. Between 17,000 and 13,000 years ago, much of Michigan's icy covering had disappeared.
> After the glaciers melted much of the state was covered in large lakes made of glacial meltwater. By 10,000 years ago many of these lakes had dried. Forests of spruce and fir grew on the newly exposed terrain.
> - The Pleistocene (plaɪstəˌsiːn), referred to colloquially as the Ice Age, is the geological epoch that lasted from c. 2.58 million to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations.

> - The Cenozoic Era (siːnəˈzoʊ.ɪk, lit. 'new life') is Earth's current geological era, representing the last 66 million years of Earth's history.
