Six passengers escaped with non-life threatening injuries after the van they were riding in slid over the edge of a Grand Canyon National Park embankment.

The National Park Service says emergency crews responded to a call Tuesday evening and found the van about 25 feet below the rim at the park's Navajo Point.

Park spokesman Shannan Marcak says two people were taken to Flagstaff Medical Center with non-life threatening injuries. Four others spent the night in a small community outside the park.

The rollover and numerous other accidents were reported around 5 p.m. amid light snow, wet roads and below-freezing temperatures.

Roads that take motorists to the western and eastern rims of the canyon remained closed Wednesday morning due to the weather.
