![]() Early Attempts on OV 0000 (Beast Cliff)Also on March 4th 2006 Gillian attempted to visit OV0000 in North Yorkshire. My first contribution to the Geograph project was a picture of TM0000, Dengie Marshes in Essex, which I reconnoitred on March 4th 2006. ![]() In particular the neologism ‘myriad’, referring to a 100km square, tied in very nicely with zero points which are by definition the meeting points of four land myriads. Until then I had never heard of geographs but I soon realised that that our Zero Point Project and the National Geograph Project had much in common. This introduced me to David Squire’s photograph and first geograph of the TA 0000 square. Discovering the National Geograph ProjectIn March 2006 I was searching the internet for information on ‘Redbourne Hayes’ our title for the zero point TA000000. Exploring grid quartets gives a much better feel of the country around each zero point, so as well as recording the exact points, we have extended our photographic mission to include interesting features within each quartet. Modern OS maps actually identify the quartets by over printing four sets of different myriad prefix letters. This led us to develop the concept of the zero grid quartet (also known as zero tetrads), that is the four kilometre squares that border a zero point. Swineshaw became the model for tackling other zero points and made us realise that any interest lay not so much in exact zero points but more in their locality. Our second zero point SE000000, Swineshaw Moor, proved more encouraging and as it lies only 15 miles from our home in Bury we have been able to return several times in different weathers and seasons. I took a few photographs but they lacked much interest. The zero point was in a field of wheat and the nearby roman route of the Fosse Way had become a disturbingly busy trunk road. To test the concept we first visited SP000000, the Fosse Way near Cirencester, but early results were not encouraging. Once we started to compile a list of the 22 land based zero points in Scotland, England and Wales we were struck by their rich variety of terrains (see Appendix One for a full list). My wife, Gillian Rimington, thought that it might be interesting to locate all the grid references with six zeros and build up a photographic portfolio of them. Zero PointsI first became aware of OV0000 in November 2005 as part of an idea to visit the zero points of the United Kingdom. The maps above show from left to right, the 500km squares or pentads of the original National Grid, the land based 100km squares or myriads covering Scotland, England and Wales and the letters of the four myriads that border OV000000 at Beast Cliff. Beast Cliff forms part of Britain’s heritage coastline and is also included in a 260 hectare site of special scientific interest mainly on account of its botany and unstable Jurassic geology. To add to its interest, access to OV is problematical. OV0000 is the only geograph square where it is possible to photograph an entire myriad and pentad with one shot! With all zero points, circumnavigation prompts a GPS to jump wildly from one myriad to another. OV000000 is the only point in the UK where four such 500 kilometre squares intersect as can be seen from the OS website map below. Each of these has a different first letter because each belongs to a different pentad. The National Grid Reference OV000000 (or zero point) marks the intersection of the four myriads OV, TA, SE and NZ. The remaining areas of both the OV myriad and the O pentad lie in the North Sea.Īs a geograph square, OV0000 only just qualifies with around 10 square metres of boulders above the high tide mark but there is an extensive boulder foreshore above the low tide level. It is also the only land representative of the much larger 500km grid square (or pentad) which is known by its prefix letter O. OV0000 – a unique grid square at Beast Cliff, North Yorkshire Why OV0000 is so remarkable OV0000 at Beast Cliff in North Yorkshire is the sole land representative of the OV 100km national grid square or myriad.
