Three very small Alpine glaciers in the Julian Alps are presented: the Eastern and the Western Canin glaciers in Italy and the Triglav glacier in Slovenia. The history of measurements usinga measuringtape andvia geodetic means on Canin glaciers is presented in brief; the majority of the paper deals with the acquisition of glacier boundaries from archive non-metrical images. The acquisition is based on interactive orientation method (mono-plotting) using lidar DTM. Seven archive non-metrical images of Mount Canin from 1893 to the mid-1970s andtwo aero-photogrametric images from periodic aerial photogrammetric surveys of Slovenia from 2000 and 2011 were used to determine the glaciers' areas. In addition, a map of Canin glaciers from 1908 was geo-referenced. Five archive non-metrical images of Triglav glacier from 1897 to 1962 were usedto determine the glacier area. Problems with obstructed areas are presented, and possible solutions are also given for deriving areas behind the obstructions. The usefulness of archival imagery for long-time monitoring of glaciers is presented, and the importance of old mountaineering publications as a source of such images is emphasized.

The Triglav glacier is situated in the Julian Alps in the northwest of Slovenia. Presented are the results of investigations and measurements of the Triglav glacier done between the years 1999 and 2012. During this period its depth was measured by means of georadar for the first time. Its area was measured on a yearly basis by means of various land surveying methods. The dynamics of the glacier shrinkage is explained by using the weather data of each respective year. Due to the glacier's concave form, accumulated winter snow did not melt until the late summer in the past few years, particularly in the central and lower sections of the glacier. If such weather conditions continue, and the amount of winter precipitation further increases, the remainder of the Triglav glacier, though small in size, will continue to exist for a few years.
