A massive emergency response from various agencies converged on the entrances to underground tunnels to help extract a group of 71 schoolgirls and their chaperones in Nyack, N.Y., Wednesday.

The group, belonging to Toras Emachu in Monsey, N.Y., was enjoying a field trip to Memorial Park. As they explored the park, they entered the Nyack Creek culvert in the southwest corner and walked through the tunnel system, reaching downtown Nyack, where they became lost and could not find their way out.

Someone aboveground heard them and called 911, resulting in Orangetown Police, the Nyack Fire Department, the Nyack Community Ambulance Corps, Ramapo first responders, Hatzolah EMS of Rockland County, Chaveirim of Rockland County and other emergency response agencies rushing to the spot to help the teens find their way out.

While some were treated for dehydration and exhaustion, no injuries were reported, and everyone was accounted for.

Nyack Mayor Joe Rand, who was at the scene, explained what happened and praised the emergency responders for their quick response.

“Some young girls, some kids, they were in the park,” he said. “They got into the culvert of the creek. And they started exploring and then they ended up not really knowing where they were and they got a little alarmed.”

“As far as I know from the police, everybody’s been accounted for,” the mayor continued. “Nobody’s missing.”

“So I just want to say how grateful I am to the OPD, Nyack Fire Department, the Nyack Community Ambulance Corps, and other first responders for their fast action and for working together so well, and how happy I am that no one was hurt,” he added.
