The Margerie Glacier in Alaska is nearly identical to what it looked like in 1941, and has been advancing for the past couple of decades.
Margerie Glacier is about 1-mile wide, with an ice face that is about 250 feet high above the waterline, but with its base about 100 feet below sea level. The glacier is about 21 miles long and extends into snow-fields in the Fairweather Range where elevations exceed 9000 feet. The ice flows about 2000 feet per year, or about 6 feet per day. It has been advancing about 30 feet per year for the past couple of decades.
