Lake Þingvallavatn at Þingvellir national park, one of Iceland’s most famous landmarks, is partially covered in a thin layer of ice. Yesterday strange patterns appeared on the surface of the lake.

In early years lake Þingvallavatn used to be covered in thick, solid ice until spring. This has not been the case over the last 15 years or so as winters have been getting warmer, according to Thingvellir National Park's Facebook site.

The lake gets partially covered in ice for shorter periods of time, and the ice is very unstable. This has happened over the last few weeks, a thin layer of ice has covered big parts of the lake.

Yesterday a local noticed a strange looking pattern in the ice cover. This is still unexplained and locals do not remember seeing anything like it before.
