- North Dakota (Wikipedia)
North Dakota ( /- dəˈkoʊtə/) is a U.S. state in the Upper Midwest, named after the indigenous Dakota Sioux. It is bordered by the Canadian provinces of Saskatchewan and Manitoba to the north and by the U.S. states of Minnesota to the east, South Dakota to the south, and Montana to the west. North Dakota is part of the Great Plains region, characterized by broad prairies, steppe, temperate savanna, badlands, and farmland. It is believed to host the geographic center of North America, Rugby, and is home to the tallest artificial structure in the Western Hemisphere, the KVLY-TV mast.
- Glacial erratic boulders of Island County, Washington (Wikipedia)
Glacial erratic boulders in Island County are a remnant of the Pleistocene glaciation that created Puget Sound and transformed the surfaces of what are now Island County’s main landmasses: Whidbey Island and Camano Island. South of Deception Pass, the two islands’ surfaces and beaches are completely composed of glacial till. Abundant glacial erratic boulders lie on the islands, their beaches, and under the near-shore waters.
