OLD FORGE, N.Y. (AP) — Authorities say three snowmobilers have died in separate crashes in northern New York since Friday.

Two crashes took place on Friday, with 46-year-old Thomas Hetherington of Middlesex, New York killed after crashing into a tree while snowmobiling in the Adirondack town of Inlet. New York Upstate reports that 23-year-old Jonathon Black of Somerset, New Jersey died that same evening near Old Forge.

Webb Police Chief Ronald Johnson says conditions in the area were very icy, and the causes of the crashes were "imprudent speed for the conditions."

New York State Police say 18-year-old Luke Tyrrell of Adams, New York died Sunday morning after losing control of his snowmobile and crashing into a tree.

Tyrrell was pronounced dead at an area hospital.
