A big hole in the ground: This is where most of the raw materials of an industrial society come from. To appreciate the scale of this excavation, note that the bright blue object on a shelf near the center of the image is a Porta Potti.
A dragline is the largest of the machines used to strip away the overburden and mine the ore layer at an open-cast mine. A bucketload for this particular dragline, one of the world's largest, is 220 cubic yards. Note the school bus, which would easily fit in the bucket.
As we walk about a site and talk to people, we can note our observations. At this stage, we try to store the information we gain in some accurate way, carry a notebook, or a camera and tape-recorder, and make small sketches. The notes we end up with can later be used to devise design strategies.
We do not just see and hear, smell and taste, but we sense heat and cold, pressure, stress from efforts of hill-climbing or prickly plants, and find compatible or incompatible sites in the landscape. We note good views, outlooks, soil colours and textures. In face, we use (consciously) all our many senses and become aware of our bodies and responses.
Beyond this, we can sit for a time and notice patterns and processes: how some trees prefer to grow in rocks, some in valleys, others in grasslands or clumps. We see how water flows on the site, where fires have left scars, winds have bent branches or deformed the shape of trees, how the sun and shadows move, and where we find signs of animals resting, moving, or feeding. The site is full of information on every natural subject, and we must learn to read it well.
