The Bottom, Netherlands
From Geohashing
This graticule is located at 17,-63. It contains the island of Saba and a tiny sliver of Sint Eustatius. Most of the graticule is water; the odds of a hashpoint falling on land are about 0.1%. However, the graticule also contains both Sint Maarten's Man of War Shoal Marine Park and the Saba Bank National Park, both of which are prime diving spots and good locations to score the Underwater geohash achievement.
