- The South Pointing Spoon (hakaimagazine.com)
On a bronze plate, the little metal spoon balances exquisitely on its bowl. Each time it’s tossed or spun, it comes to rest with its neck aiming south. This is a replica of the aptly named south pointing spoon, thought to be the first magnetized object ever used to tell direction. And it was the crucial precursor to the magnetic compass, one of the most important inventions in maritime history.
- Interstate State Park (mnopedia.org)
The Interstate State Park, located on 295 acres in Taylors Falls, is the second-oldest state park in Minnesota. Created in 1895, its unique topography and geological history draw many visitors to the area. It is the first park in the United States to be located in two states, Minnesota and Wisconsin, with the St. Croix River serving as the border. The two parks are operated separately by the states’ Departments of Natural Resources.
- Compass (Wikipedia)
A compass is a device that shows the cardinal directions used for navigation and geographic orientation. It commonly consists of a magnetized needle or other element, such as a compass card or compass rose, which can pivot to align itself with magnetic north. Other methods may be used, including gyroscopes, magnetometers, and GPS receivers.
