One week after a large sinkhole developed in a wooded area in Ringwood, the leader of the Ramapough Lenape Nation says his clan is very worried about the condition.

Vincent Mann is chief of the Ramapough Native American Turtle Clan. Mann says that a 50 feet in diameter sinkhole is near power lines, and he says he wonders what would happen if the lines were affected.

He also says there's no guarantee another sinkhole will not pop up near their homes or where the children get the school bus. There have been several cases of the ground collapsing near the abandoned mine shafts that are all over Ringwood.

Ringwood officials have put a fence around the hole to keep people away. Assessments were made Wednesday to consider putting up permanent fencing around the area.

Chief Mann says that he thinks the best solution is to get away from the sinkhole, and he wants help for the entire community to relocate.

"My first obligation is the safety of my people," Mann says. "That's not to put a fence up, it's not to fill in [the hole] with dirt."

Ringwood officials tell News 12 New Jersey that a plan of action to fix the hole will be announced soon.
