How the USA States Got Their Shapes
Map Group July 2024
Presenter: Keith Treschman

Keith has taught Science for over 40 years in Queensland secondary schools. He holds a PhD in Astronomy, an area in which he is passionate. He has visited the 7 continents and enjoys geographical places, for example, Hawaii, Great Rift Valley of Africa, Galápagos Islands, Jordan River and Antarctica.

On a map of the USA, one notices some straight horizontal and vertical lines, but then there are also angled lines, non-straight lines, lines with no apparently defined shape. Keith will explain these features by reference to history and geography.
