Snow Seas

Snow seas are large lakes of liquid like snow that has congregated into large valleys inArctus. The snow in the snow seas flows similarly to water, but it's now wet, but it's heavy enough to flow downwards like water. Going into the liquid snow won't get you wet, but it is incredibly cold.
Snow seas are very remote, being so far north and far away from any large settlement. They are considered some of the most beautiful sights in the world, they also have mountains near them and the northern lights often glow in the skies above them.
