Rubber Duck
Volcano
A volcano represents permanence on a geological timescale. The Hawaiian volcanic chain has been continuously active for approximately 70 million years. Olympus Mons on Mars, the solar system's largest volcano, has existed for billions of years with minimal change to its fundamental structure. This is durability that transcends human comprehension.
Even extinct volcanoes persist as landscape features for millions of years, their eroded forms serving as monuments to ancient tectonic activity. Whilst individual eruptions are ephemeral, the volcanic system itself represents one of the most enduring features any planet can produce. Against such timescales, the rubber duck's decade of service appears momentary indeed.
