About this earthcache
Most of the Tors on Dartmoor are formed from igneous rocks, the word igneous comes from the Latin word for fire. Igneous rocks are formed from hot molten rock called magma. These rocks may be formed after the magma reaches the surface such as during a volcanic eruption or well below the surface when it intrudes its way into cracks underground and cools under pressure. These underground rocks are knows as plutonic or intrusive rocks. Granite is one type of plutonic rock. Hard as granite is, it yields to the beat of the weather on the face exposed to the prevailing rain-bearing wind.
Oke Tor forms part of the Belstone range and has three main piles. The tor’s centre pile is weathered at the north end into rounded spurs. The third northernmost pile is notable for its giant rock-parting. Further north again is a pile having a miniature rock-parting into which a former summit slab has fallen and remains upright. Some tors have wide partings at vertical joints – these are due possibly to the action of frost, being struck by lightning or an earthquake.
The given co-ords will take you to a part of Oke Tor.
