In addition to the two types of landscape photography compared above (wild landscapes, and landscapes with signs of human modification), there's yet a third type that I find especially fascinating to photograph, that of ancient ruins. In a way, it's the inverse of a "natural landscape with human traces", being instead of man-made landscape reverting to wilderness.
For photography, all three types of landscapes have power and interest in their own ways. I enjoy photographing all three. Sometimes I clone out the poles intruding into the otherwise pristine-looking wilderness, sometimes I leave them and the other human structures in, and sometimes the human structures are what I'm focussing on, as appropriate for what I'm trying to convey with the image.
Having traveled extensively in both the western U.S. and Europe, I can confirm that European art and photography don't often contain pristine wilderness just because there's so little of it left in Europe. It's far, far easier to find in the western U.S. I've hiked in both the Swiss Alps and the Sierra Nevada, and the experience is very different. In much of the Sierras, you can hike all day and, once you leave the trailhead, see no sign of humans whatsoever except for the little primitive trail you're on; I've been hiking on a holiday weekend on one of the less well-known trails and not even seen another human being. In the Alps, there are lifts, farms, signs, and restaurants all over the place; comfortable and convenient, but not a wilderness experience by a long shot.
