Which part of Earth most likely has the highest albedo value?

Ice reflects much more sunlight than choppy ocean water, so the highest albedo is among the smooth-ice choices. A Sun only 15 degrees above the horizon shines at a lower angle than one at 30 degrees, causing more light to reflect from the smooth surface rather than enter it. Therefore, smooth ocean ice with the Sun at a 15-degree angle has the highest albedo.
