Located in a median near Parking Lot E in the southwest, the sinkhole is believed to have been caused by a leak in a storm drain and worsened by recent rain and snow storms.
"With as wet as it is and as much snow as we've had, it's not to be expected but completely understandable," said school spokeswoman Ashley Van Essen.
She said campus staff are keeping an eye on the sinkhole to ensure it does not pose a threat to persons or property. She said repairs are not likely until warmer weather dries the area later this year.
An email to faculty and students was sent Wednesday morning and said the sinkhole was "of no threat to the campus community."
