Before one of our hikes in the area, we decided to check out what was at the end of this staircase. Turns out there was nothing there... except for a spot to hide a cache of course. The easiest access is from Viewridge Rd, although you can also park on Chagall Rd.
UPDATE 9/27/15: Cache is now a bison tube. Bring your own pen. Please be careful when retrieving & replacing the container.
The cache is less than .1 from parking, or about 100 stairs (one way).
