Mapping Washington State’s Glacial Legacy

Mapping Washington State’s Glacial Legacy Presenter: Daniel Coe, Washington Geological Survey Glaciers from last ice age left long-lasting imprints on the topography of Washington State. Geologists and cartographers have been unraveling this glacial landscape since the late 19th century. The Washington Geological Survey has recently created many new maps that build upon this rich cartographic inheritance by fusing earlier data and techniques with modern insights and technology. We will compare and contrast examples of our newest glacial—themed maps with their historical predecessors. This presentation was made at the 2018 annual meeting of the North American Cartographic Information Society (NACIS) in Norfolk. For more information on NACIS, check out http://NACIS.org.
