NAME AND LOCATION OF CLOSEST CLIMATE STATION (latitude, longitude, and distance from borehole, km) – provide (if available) mean monthly air temperature and snow depth of reporting interval for mean annual ground temperature
Big Almatian Lake (Bolshoe Almatinskoe Ozero), 43 04'N, 76 59'E, 2506 m a.s.l. and 8 km beyond the K0 site by road
Data for period 1932-2000: see table.
Depth: 25 m Drilling Angle: 90 ° Diameter: 7.6 cm
Drilling Method: core drilling Date Drilled: 01. Jan 1973
Type: 38 km beyond Almaty city, last 16 km earth road (4-wheel drive vehicle) Distance From Road: 0 m
Type: laboratory building, not heated Distance From Heat: 10 m Other Disturbance: residential construction, heated Distance From Heat: 20 m
Permafrost Thickness: >20 m Permafrost Zone: Discontinuous Vegetation: Site has no vegetation, but surrounding territory can be classified as tundra Landform: Upper Pleistocene and Holocene morainic complex Lithology: During deep excavations (up to 10 m) near the K0 site massive cryostructures, were present deeper than 4.0-5.0 m. The largest ice bodies reached 15-20 cm in size. Iciness of permafrost varies from 5 to 40%. Above 4.0-4.5 m, the grounds has a red-brown color with obvious ferrate traces. Predominant: gravel, fragments of stones and sand without soil layer. Morphology: Site is located near the mountain pass Zhusalykezen
