I saw this circle-o-bricks while hiking at Ijams on Valentine's Day with my sweetheart and my dog. I have been to Meads Quarry at Ijams several times but have never noticed these bricks. I wonder what they are / why are they there? You can see them on the quarry loop trail near the owl themed water tower. And if you haven't been hiking on a brisk winter day, I strongly suggest it. Downed leaves and crisp winter air provide some nice clear views this time of year.
