The expedition of last summer was a hasty reconnoissance, during which but little detail work could be undertaken. The actual study of the ice-fields of the St. Elias region remains for those who come later. {189} PART V. HEIGHT AND POSITION OF MOUNT ST. ELIAS. The height and position of Mount St. Elias have been measured several times during the past century with varying results. The measurements made prior to the expedition of 1890 have been summarized and discussed by W. H. Dall, of the United States Coast and Geodetic Survey, and little more can be done at present than give an abstract of his report. The various determinations are shown in the table below. The data from which these results were obtained have not been published, with the exception of the surveys made by the United States Coast Survey in 1874, printed in report of the superintendent for 1875. _Height and Position of Mount St. Elias_. -----+--------------------+-------------+-------------+------------- Date.| Authority. | Height. | Latitude. | Longitude W. -----+--------------------+-------------+-------------+------------- 1786 | La Pérouse | 12,672 feet | 60° 15' 00" | 140° 10' 00" 1791 | Malaspina | 17,851 " | 60 17 35 | 140 52 17 1794 | Vancouver | ----------- | 60 22 30 | 140 39 00 1847 | Russian Hydrogra- | | | | phic Chart 1378 | 17,854 " | 60 21 00 | 141 00 00 1847 | Tebenkof (Notes) | 16,938 " | 60 22 36 | 140 54 00 1849 | Tebenkof | | | | (Chart VII) | 16,938 " | 60 21 30 | 140 54 00 | Buch.
