A couple of hundred metres west of St. Felix School, very close to a public footpath, Southwold Suffolk, UK.


Expedition Plans[edit]

It's World Geohashing Day! Wo-hooo! And it's the End-Of-The-World! Oooooooh! So this will be my last ever geohashing expedition. My plan is to arrive at 4pm, well before the global earth quake, leave a marker and retire somewhere more comfortable to watch the end of the world and join the raptor rapture at 11 p.m. local time!

Delayed - new ETA 17:30 to 18:30.

The world ended as predicted at 22:00 UCT. I'm writing this from a parallel reality in the multiverse where the closest I got to Rapture was a most excellent Czech Pilsner Lager.

The Expedition[edit]

It was a clear sunny evening with a significant sea breeze. The public footpath followed the perimeter of the school grounds and led to a point 29 metres from the hash. There was a low fence leading into a paddock. Over the fence and 29 metres later the hash was still 20 metres away on the far side of a deep tree lined drainage channel. This was GPS wierdness. There was a clear view into a sweet-corn field where the hash must be located. So after some back tracking, a short leg on the main road and a traverse of the edge of the sweet-corn, the GPS decided the hash was 20 metres away back in the paddock. Damn! The tree lined drainage channel was only about ten metres wide at this point but very densely overgrown, deep and wet. So which side was the hashpoint on? Google earth shows it clearly in the paddock so either way it's co-ordinates reached.

Atmospheric Refraction[edit]

Several geohashers have reported that their GPS receiver refused to reach zero. I also have experienced a hash when the GPS reached zero. By the time my camera was ready to capture the evidence, the GPS said the hash was 20 metres away. Just standing still, the GPS said I was wandering around and the track log left a random scribble. On that day there were huge convection clouds and heavy showers. I believe today also, was a day of unstable air. The cool dense damp sea breeze was undercutting the warmer drier less dense mainland air making a giant wobbly jelly prism. The error was only ten or twenty metres but that was sufficient to cause the muddle.

Of course the GPS disturbance might just be a precursor of the end of the world!
