The Poroharju esker in the Käsivarsi Wilderness Area, Finland. I captured this photo during my six-week solo winter hike. Esker is a large and extensive formation made of sand and rocks, and is quite common in Finnish landscapes. These eskers were formed during the Ice Age by melting water from glaciers.
