Dartmoor, the latest title in the highly successful and innovative British Mountain Map series, is the only really detailed map for walking to cover this famous area on one sheet. XT40 - A new generation of tough polyethylene maps. These maps are a leap forward in technical excellence. Tough, durable, and 100% waterproof, they are compact - not the great bulky package you get with a laminated map - and light to carry. This all - weather British Mountain Map for climbers, hill - walkers, mountaineers and mountain bikers is published by HARVEY in co-operation with the British Mountaineering Council. The colourful geological map on the back gives understanding of the land form and was specially designed by the British Geological Survey. Colour shading is also used for easy identification of hills and valleys. Mountain incident, first aid and navigation advice as well as useful local numbers and website addresses are also on the reverse side of the map.
