Mysterious Burn Zone Near Lake Anne Dumbfounds Tens

Please to be enjoying this bizarre photo of fire damage along the hillside that (at times) successfully separates Lake Anne from Wiehle Avenue drivers. First noticed by several vigilant Restonian operatives over the weekend, its cause remains unknown -- especially given its seemingly deliberate rectangular dimensions. Was it a careless Loudoun County cut-through commuter motorist, tossing a cigarette into the tall grass? Was it a controlled burn, perhaps to eradicate the scourge of Reston paths, or maybe poison ivy? Or was it... something more sinister?

Being a responsible "web log," we will apply Occam's Razor and suggest the theory that makes the most sense: trainee UFO pilots practicing making crop circles by creating the less well-known crop rectangles. You're welcome.
