Ravens wide receiver Torrey Smith has noticed something funny lately. “The sky looks weird in Baltimore,” he tweeted last evening. He was referring to yesterday’s weird sunset, which had some people half-convinced that an alien mothership was about to land on the city. But he could’ve just as easily been referring to any number of recent dramatic sunsets–which led me to wonder, just why have Baltimore’s autumnal evenings been so colorful recently?
Every year on March 13, I wake up with the nagging feeling that I’ve forgotten something important. And I have: Baltimorehenge. That’s the name for one of the two days each year where the sun’s alignment matches up perfectly with the city’s street grids, resulting in an urban “canyon sunset” precisely between the city’s east-west street canyons.
