The cache is a small rubbermaid container. Original contents include:
A rock (of course), a small polished pebble of amethyst
A small candle, to help brighten what is probably an overcast day
Plymouth Prowler toy car, because there are only ever trucks out on the island
Sports Illustrated wrist watch, to help pass the time
Carhart stocking cap, to protect your ears from the bitter biting wind
Puffin stuffed animal, because puffins visit the island in the summer
A bottle of water (Clearly Arctic, 100% Pure Alaskan Water), because you really don't want to drink the (suspect) water on the island
A one million dollar bill, not that money will do you much good out here
Whitebeard the Wandering Wizard TB, whom I met back on the Alaskan mainland; said he wanted to wander in search of adventure, so I brought him with me to THE ROCK AT THE EDGE OF THE EARTH!
