BCP162 - Calgary Renfrew
Quick drive up cap.
Although I see I'm not the only one to spot the hole first. I saw the hole filled with garbage and leaves which was nicely insulating a plug of ice which I pried out with my ice scraper. Then there was the layer of mud which brought me to... a pin (D'oh!).
I turned my head and found the orange-painted cap with an orange-painted stake laying next to it. The paint was too thick to make out the markings very well.
