On my walk to this cap I saw my first robins of the season and a duck flew up out of the grass right beside me. The cap took a few minutes. I found CanadianRockies old log giving explicit directions: "The cap is flush with the ground and 10 feet SSW of the medium-sized white rock." As I scanned the ground I discovered it right behind me - how'd I miss that?? Thanks CR for the helpful log.
