Atomic Shrimp | Chesil Beach Pebble Survey Part 2 - Gravel Positioning System (Also, What if Everyone Took a Stone?) @AtomicShrimp | Uploaded September 2024 | Updated October 2024, 3 days ago.
There's a local legend that sailors landing on Chesil Beach in fog, or at night, would be able to pick up a handful of gravel from the beach and accurately estimate their position on this 30 kilometre-long beach. In part 1, we captured the data; this time, we'll test the legend!
