Changes in mountain glaciers in Northeast Russia from the little ice age to the mid‐20th century

The authors assess the retreat of the poorly studied glaciers of the Russian Northeast from their maximum extent during the Little Ice Age, utilizing remote sensing and historical data. The basic indices of change utilized were the linear distance from the end of the glacier to its moraine and the difference in absolute elevations of the end of the glacier and the moraine; these were calculated for 23 glaciers in the Kodar Range, 37 glaciers in the Suntar‐Khayata Range, 52 glaciers in the Cherskiy Range, and 63 glaciers on the Koryak Upland.
