Nauman’s staircase sculpture at Oliver Ranch is a response to the physical contours of the land it crosses. Though all the treads are exactly the same size, 30 inches square, every riser is different and measures the land’s changing contours every 30 inches for the length of the staircase, almost a 1/4 of a mile. The smallest step is 3/8 of an inch; the largest step is 17 inches. In classic Nauman fashion, about the time you want to look at the view, you need to focus on your feet or you may fall because of the changes in step height.
