 His treatise ""Draft of a Physical, Geographical, and Historical Description of Icelandic Ice Mountains on the Basis of a Journey to the Most Prominent of Them in 1792–1794"" was submitted to the Danish Society of Natural History in 1795 though it languished there for almost a century.Not until the 1880s was the Danish manuscript published in part; in 1945 it was published in its entirety in Icelandic by glaciologist Jón Eyþórsson.Due to its isolated location Iceland remained a remote location for geological investigation until the 20th century.
