Varvara's Travels April 15-22, 2012
Varvara appears to be moving pretty consistently west now. She is NW of Unimak Pass along the edge of the ice (shown in white for the most recent image). This image may give the wrong impression of a solid edge. Actually, the ice extent data includes broken up and floating ice.
