Main changesdetected by using satellite data:

• Consequences of geological prospecting at Nesterovskiy and Chudnoye subblocks of Alkesvozhskiy block on gold are obvious at satellite imagery since 2011, June

• High volume of suspended matters eroded from Nesterovskiy subblock cause a great turbidity of Grubependity lake’s water

• Anthropogenic transformation is taking place also outside of Nesterovskiy and Chudnoye subblocks (ex: new facilities on the road to Chudnoye subblock)
