Guard Island Big Island Nest is located in the tallest clump of trees, about 180 feet south of the lighthouse. It can be seen from both sides of the island. From the GPS given, look back at the lighthouse, then to the left to the tallest clump of trees. This nest is nearly at the top of this cluster of trees. It is active every other year, alternating with Little #2 for the past several years. Look for Harbor seals on the rocks or in the Bull Kelp (sea weed).
