Our Fox Mulder-esque search for the truth about this morning’s blasting continues! DCist was able to get in touch with Shannon Whalen-McDaniel, a spokesperson for Arlington County, regarding the possibility that the noise had originated from the work which is currently going on at the Rosslyn Metro station.

The County is installing a shiny, new entrance to improve access to the station, and the project’s excavation process recently hit bedrock, so a series of controlled blasts have been required. But according to Whalen-McDaniel, that’s not what woke you up this morning.

“Ours has been really going on undetected,” she said, adding that “there are a lot of measures in place” to limit the noise coming from the Rosslyn Metro blasts. Besides, says Whalen-McDaniel, “we didn’t blast today.” Foiled!

Another rumor that has been making its way around is that the noises were coming from construction work on a private development by Monday Properties at 1812 North Moore Street in Rosslyn. But that can be ruled out, too: “It was too early for 1812 North Moore,” said Whalen-McDaniel. Foiled again!

But we didn’t strike out — Whalen-McDaniel added that there’s been some recent cannon firings at Arlington’s Fort Myer which may have been the root of the noise. DCist has contacted the base to confirm that they were indeed firing their artillery around 6 a.m. this morning, but have not yet heard back from a spokesperson — normally, the cannon fire only goes off later in the morning, but we’ve got a good feeling that this might be our ticket.

One way or another, we’ll get to the bottom of this. Wake the District at your own peril, noisemakers!
