[Daily Photo] Beautiful ice patterns on First Sister Lake / 姊妹湖上的冰花

I went to Dolph Nature Area in west Ann Arbor yesterday. There are two sister lakes in this area: First Sister Lake and Second Sister Lake. The lake in this photo is the First Sister Lake. You can park your car in the parking lot beside the Second Sister Lake and hike about 15 minutes to get here (Thanks to my GPS). There is a small dock on the lakeshore. I had a good time taking pictures from the dock. Look at the beautiful ice patterns on the frozen lake surface. The ice maybe had melted last week and froze again recently to form these amazing patterns.
