i made a plasticine picture of mount everest. it's very realistic with the little tents at base camp and the prayer flags strung up and the khumbu icefall, all pocked with crevasses and snow.
it seems much less daunting in miniature. maybe molding is the safe approach to mountains! no frostbite or altitude issues! though your hands will smell of plasticine, it's a small price to pay for sculpting the summit.
