Abstract
From February 20 to March 27, 1967, four glaciers near Mt. San Valentin (46°35'S, 73°20'W, altitude 4, 058 m) in northern Patagonia were surveyed by the second Patagonia Expedition of Hokkaido University and Hiroshima University. The glaciological and meteorological works carried out on these glaciers are described and some results are given. The firn line in this region was observed to be 1, 2001, 500 m above the sea level. The mean ablation-rate for five days measured on the lower stream of the Soler Glacier was 9. 2 cm/day, when the mean air temperature was about 11°C. The mean surface flow velocity along the central line of this glacier was approximately 40 cm/day.
