We've all heard of Stonehenge, some of us have heard of Manhattanhenge, but a website called SunCalc enables us all to think of our own cities as Carrollhenge or Des Moineshenge.
To figure out if this happens in your city or town, a website called SunCalc allows you to calculate the angle of sunrise/sunset from any vantage point on the planet. With this information, you could figure out when your surroundings mark sunrise or sunset. You enter a location and a date, then SunCalc determines the angle you would see the sun rise or set.
This Saturday looks like a good match between the sunset and the downtown Des Moines street grid. February 8th looked like a good date to watch the sun rise in downtown Carroll.
How does your city line up?
