[Daily Photo] A tree branch and ice patterns in a frozen lake / 冰封於湖中的枯枝以及湖面的冰花

I was in Dolph Nature Area (in Ann Arbor, Michigan) near the Second Sister Lake. I found a tree branch half-frozen in the frozen lake. Beside the branch there were beautiful ice patterns. It looked like someone had written strange alien words on the ice surface.

湖面的冰花看起來就像是奇異的外星文字。
