(CBS) — It’s turning out to be a “December to Remember” for a Near North Side auto dealership — but not because of post-holiday sales.

Tons of salt buried cars parked outside the McGrath Acura dealership Tuesday when portions of the south wall of the adjacent Morton Salt storage facility collapsed.

No one was hurt and no extrications were necessary because of the spill, at 1301 N. Elston Av.

The Chicago Fire Department, Chicago Dept. of Buildings and Morton Salt all said it appears that salt was merely piled too high in the storage building, causing the wall to give way.

“It appears to be a case of too much salt and too little wall,” said Fire Department spokesman Larry Langford said.

First responders quickly determined that all employees of the Morton facility and of the adjacent McGrath Acura dealership were accounted for and unhurt, and that no one else was buried in the salt.
