Was it a sinkhole, a landslide or a street collapse?
Whatever you call it -- and Baltimore officials first used the term sinkhole Wednesday to describe the action as a block-long section of street collapsed and slid down a hill -- it's amazing to watch.
Check out this YouTube video of an SUV tipping over and then vanishing from view down into the chasm below.
Vehicles in North Baltimore vanished one by one Wednesday afternoon, burying train tracks at the bottom of the slide and prompting warnings from emergency officials for residents to avoid the area.
Posts on Twitter and Facebook from workers and residents in the area of 26th Street between Charles and St. Paul streets showed photos and video of vehicles teetering on the crumbling street, with overturned vehicles resting below at the bottom of the collapsed area.
