A 1904 study of volcanic phenomena by an adventurous American geologist who documented the activity of Mount Pel?e in Martinique.In this 1904 study, American geologist and explorer Angelo Heilprin (18531907) documents the temporary formation of a 'tower' of lava that resulted from the devastating eruptions of Mount Pel?e in 1902. This account of his third visit to Martinique is complemented by unique photographs depicting volcanic activity and its aftermath.In this 1904 study, American geologist and explorer Angelo Heilprin (18531907) documents the temporary formation of a 'tower' of lava that resulted from the devastating eruptions of Mount Pel?e in 1902. This account of his third visit to Martinique is complemented by unique photographs depicting volcanic activity and its aftermath.Born in Hungary, the geologist Angelo Heilprin (18531907) moved with his family to the United States as a boy. He later left New York to study natural sciences in distinguished European institutions, and went on to hold academic positions in Philadelphia and ultimately at Yale. His teaching duties were interspersed with expeditions to Yucatan, Greenland and other places of geological interest. This 1904 study, complemented by unique photographs, depicts his third visit to the island of Martinique in the aftermath of the devastating eruptions of Mount Pel?e in 1902. Heilprin documents the temporary formation of Pel?e's 'tower', a monolith of lava that grew rapidly after the eruptions, reaching a height of 300 metres before its collapse. Heilprin also summarises the chief features of volcanic eruptions and directs readers to his 1903 publication Mont Pel?e and the Tragedy of Martinique (also reissued in this series) for further information.1. Martinique revisited, and a fourth ascent of Pel?e; 2. The tower of Pel?e; 3. The after-history and nature of the tower; 4. Further observations on the phenomena of Pel?e; 5. Some thoughts on volcanic phenomena suggested by the Antillean eruption;lc#
