The author of this work is the Estonian geologist and mineralogist Konstantin Grewingk (1819-1887). He was a Professor of Geology and Mineralogy at Derptskogo University (1819 - 87) and Director of the Fersman Mineralogical Museum in St. Petersburg from 1854-1857. Grewingk traveled extensively  in Russia and also present day Alaska studying the geology, mineralogy and archeology of many areas. He wrote the first good description and prepared the first map of the famous emerald mines of the Urals in 1854. His work on the Baltic region provided some of the first accurate descriptions of the stratigraphy of the region. His travels and observations of the geology of Siberia, Alaska and California contain some of the first descriptions of the geology and maps of Alaska. Where ever he went, Grewingk collected mineral specimens and these became a part of the Fersman Museum collections. His above study is an early and accurate contribution to our knowledge of Northwest America and its adjacent islands. The work is in German and contain a wealth of information.
