Polar Weather

Dagrún gazed into the valley where the sea gut into the earth. Rocky forms towered on either side of the valley and she gazed for awhile at a water fall that rushed its way from the very top of a nearby rock face all the way into the sea below. At this distance the sound was particularly relaxing, providing a background ambience to their exploration. "This is a neat place." She padded closer to the edge of the water before reaching out and daring to dip her paw in. She scuttled back. The water was absolutely frigid, far colder than the waters of the Rio Grande. "So, why do they call it the Polar Sound?" Was it because the waterfalls were making sound?
