Lake Superior Ice Cover
16" x 16" x 1" (41 x 41 x 3 cm)

Embroidery on silk.

Lake Superior is, by surface area, Earth’s largest freshwater lake, with enough water to cover North and South America in one foot of water! Fresh breezes from the Northwest blow across the lake picking up moisture and delivering 200 inches of winter snow to the Keweenaw Peninsula where I live. I can cross
country ski during 5 months of the year. But higher air temperatures are leading to increases in Superior's surface water temperatures and to less ice formation on the lake. This embroidery details some of the physics and consequences to declining ice formation.
