Ice Dive by Viktor Lyagushkin. Lazurny (Russia) is an old neglected quarry, totally filled with ground waters. Pine trees and bushes on its bottom remain green for many years. In winter the quarry is covered with thick ice and snow. The circles and rays on ice “sky” are man-made. According to Russian ice diving standards the snow should be removed from the ice in such a manner as to let divers orientate themselves beneath the ice and easily find their way back.
