Rope-jumpers pictured leaping into crater

A member of the "Exit Point" amateur rope-jumping group takes a rope jump from a 120-meter (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, outside the town of Tuim in Khakassia region, October 18, 2014. The cavity was formed at the site of wolframium, molybdenum and copper underground mines due to numerous explosive works in the middle of the 20th century which influenced the fall of the hilltop. Fans of rope-jumping, a kind of extreme sport involving a jump from a high point using an advanced system of amortization including mountaineering and rope safety equipment, arrive at Tuimsky Proval for about a 5-second-long free flight with speeds of up to 180 km per hour.
