I’m a city person. I seldom see the horizon. What I probably share with you, whether you are a city person or not, is the habit of looking at tall things. Trees, poles for street lights, even buildings, set a scale for my judgment of distance. I found myself completely lost in the desert. In the flat landscape which extends all the way to the horizon, I could not gauge distances. I saw a man striding towards me, and took the featured photo. I thought it might take him a quarter of an hour to get near us. It was more like five minutes.
Later I saw this cow sitting in the distance, chewing its cud. Far far away, I thought. It got up, ambled past us and was lost in the distance; all in the space of ten minutes. My eyes could not adjust to this completely flat landscape. If there was a line of electricity pole marching from horizon to horizon, I might have been able to use that to estimate distances. But without any vertical cues, I completely failed.
A little walk later I saw this tree sandwiched between two hills. Later I looked at the photo and thought, “Just a minute. Hills?” No, in this desert there are no hills. The tree is the usual stunted acacia tree. It gives us a scale for how large things are. The bumps around the tree are just two heaps of sand, not very high. Looking again at it, I realized that the picture also has two electricity poles which are higher than the “hills”. The poles here are not very high, so that limits how high these piles of sand and dust are.
I didn’t stay in the desert long enough to get used to gauging distances. Wherever I looked I was deceived.
