A member of the “Exit Point” amateur rope-jumping group takes a rope jump from a 120-metre (394 feet) high rock down to a man-made crater called “Tuimsky Proval” (Tuimsky cavity), with the air temperature at about minus 15 degrees Celsius (5 degrees Fahrenheit), outside the town of Tuim in Khakassia region, October 18, 2014.
