Warden Hill side view

2 cones of 195 metres of cotton yarn are coated in cyanotype and taken to the top of Warden Hill, the highest point in my local area. One thread was tied to the top of the triangulation point which is 195 metres above sea level and then walked and unraveled travelling down the hill. After ten minutes of exposure it was rewound. This process was repeated with the other cone going in a different direction.
