Count the rings

Ronna and I encountered this bighorn sheep -- not to be confused with the mountain goat -- during our recent visit to Canmore, Alberta. The age of this agile animal can be determined by counting the rings on his horns. I did not venture that closely to check out his rings, but he seemed docile enough, considering we were after all invading his personal space.

It was a grand whirlwind tour. More photos to come...
