Jim Denevan 西伯利亚冰圈大型艺术造型，是由一位俄罗斯的艺术家Jim Denevan在2010年创作，从高空中观看的话，有点外星人造访过这里一样，巨大的螺旋造型占了贝加尔湖九平方公里的区域。

Looking at these crazy pictures, you’d think aliens had landed on the North Pole to create ice circles, but obviously that isn’t the case. These incredibly huge spirals were created by artist Jim Denevan and his crew who in 2010 created a large scale artwork on the frozen surface of Lake Baikal in Siberia, Russia.

In a quest to create the world’s largest work of art, Jim and his team drew these beautiful patterns by carving into the fresh snow on the frozen lake, using the white of the snow to contrast with the dark ice. Incredibly the whole thing ended up spanning an area of nine square miles. The photos say it all.
