Abstract. In the August 2014 we performed repeated survey of the Kolka Glacier cirque. Our investigation included ground-based topographic survey (scale 1:5000), ground stereo survey using calibrated digital photocamera, stereo survey using unmanned aircraft system and stereo
survey by SPOT-6 satellite. We compared and analyzed advantages and defects of the approaches listed above in mountain terrain. Joint use of traditional and innovation techniques allows to create most precise digital elevation models of the glacier surface, assess the rate of the
Kolka Glacier regeneration and verify forecast of events similar to the 2002 disaster. We register accumulation of 30 M m3 in the Kolka Glacier cirque and 800 m advance of the glacier terminus in 2004–2014 despite unfavorable conditions for Caucasus glaciers. Rapid glacier advance is a unique case for the Caucasus in the 21th century.
Keywords: alpine glaciers, glacier disaster, natural hazards, remote sensing, forecast.

Abstract. In article are cited data about glaciers and rock solid glaciers of a northern slope of a massif of Chach – Kaydzhana (Central Caucasus Mountains, Kazbek-Dzhimaray massif). Questions of dynamics of degradation of a freezing are considered. Data on stone glaciers of this
massif are provided for the first time. Complexes of stone glaciers of this area are sources of clear sweet water.
Keywords: Caucasus, Kazbek-Dzhimaray massif, glaciers, stone glaciers, degradation of a freezing.
