LANSING, N.Y. (AP) — Seventeen miners are stuck in an elevator 900 feet underground at a central New York salt mine and emergency crews are working on a rescue.

Emergency management officials say rescue equipment is on the scene and the miners aren’t in danger.

Tompkins County Emergency Management officials say the miners have been trapped since late Wednesday night at the Cargill Salt Mine in Lansing, about 40 miles outside Syracuse.

Authorities tell local media that they’re able to communicate with the miners and have managed to get them blankets, heat packs, and other supplies.

Cargill’s website says the mine just north of Ithaca has been in operation since 1922 and annually processes about 2 million tons of road salt that’s shipped throughout the northeast United States.

Messages left at Cargill’s corporate headquarters were not immediately returned early Thursday.
