No plans this Saturday? No worries. If you’re anything like us and are totally transfixed by the sprawling, sand- and ice-sculpted art of Jim Denevan — this event is right up your alley. The famed land artist, renowned for skillfully using mother nature as his medium, will be on site at Anthropologie signing copies of his latest tome, Jim Denevan: Lake Baikal. Pop into the Union Square location and read the super-inspiring tales from Jim’s latest adventures atop the Siberian tundra. You'll get to enjoy tasty refreshments and meet the sandman himself! Sounds like a superb Saturday morning plan to us. Details below.
