This is the field above the Meldon Reservoir car park, Okehampton, Devon, in the Dartmoor National Park. Taken from the carpark at Meldon Quarry. I have tried to take this before but I only had the 18-55mm then and it was too far away!

The row of trees on the left are these which go all the way down to the edge of the reservoir.
