A massive sinkhole opened up in the middle of a mountain road during a rainstorm. It suddenly formed and swallowed two full cars on Mines Road near Lowell on April 20 2013. The vehicles fell 5 feet straight down before sinking another 20 feet. The cause could be a violent flashflood that would have uprooted a plastic culvert and the asphalt on top, thus creating a 30 feet wide and about 25 feet deep sinkhole.

Officials believe a quick rainstorm caused a flash flood, which was too violent for a 5-foot plastic culvert installed in the road to handle. As a result, the conduit uprooted and the asphalt on top gave way, opening into a sinkhole 30 feet wide and about 25 feet deep.
