Grinnell Land
a barren, mountainous Polar tract, in lat. 80° N., separated from Greenland by Smith Sound and Kennedy Channel. It was discovered by by Lieut. E. J. De Haven, and named after Henry Grinnell, of New York. Lieut. A. W. Greely thoroughly explored it. N. and S. it is covered with ice-caps; between them lie valleys that lose their snow in summer, and support herds of musk oxen and the usual Arctic fauna. In the interior Greely discovered Lake Hazen, 65 miles long, and two ranges of mountains, one containing a peak (Mount Arthur), 5,000 feet high.
