There are only 6000 tule elk left in the world, all of them found in California. Some of them roam along the coastal hills of Point Reyes National Seashore, an area that is also occupied by cattle and dairy ranches. To protect grazing land for cows, some of the elk are confined by high fences. But as drought worsens, and the elk are cut off from food and water, large numbers of them are dying. A band of activists have been trekking through the fog, in darkness, to try to help them.
