For the IIDA Northern California event in September, our group had the opportunity to do a hiking tour of the Oliver Ranch close to Geyserville, California.
Among the art pieces, the final one was Bruce Naumann concrete staircase sculpture at Oliver Ranch, described as his response to the unique physical contours of the land at the Oliver ranch in Geyserville, California.
All of the horizontal the treads are exactly the same size, 30 inches square, and then every riser is of a different height with the total length covering a 1/4 of a mile. The smallest rise is 3/8 of an inch; the largest rise is a vertical 17 inches. It is a treat to feel your legs stretch and strain as you descend, and I cannot even imagine the ascent.
As you descend you must pay attention to your steps and your feet or you may trip and fall because of the steep changes in riser height.
