Unstable conditions in the Catskills and Adirondacks have led the state’s Department of Environmental Conservation to warn hikers and skiers they should “exercise an abundance of caution” and consider alternative plans.

“Warmer temperatures and rain have contributed to intense, severe, and dynamic conditions across the Adirondacks and Catskills,” says a DEC release. “Key winter routes are now impassable due to washed out bridges, thawed water crossings, and flooding.”

Even on trails that are still navigable, compacted snow may appear to be a solid surface but often leads to post-holing or sinking through to the ground level. This can happen with boots, skis, and even snowshoes.

DEC staff have encountered up to two feet of standing water on frozen lake surfaces, damage to high-water bridge crossings, and snow slides on steep terrain.

“A passable stream at the start of a hike can quickly become a life-threatening crossing on the way out,” the DEC warns.

The DEC advises recreationists to know their route and multiple alternatives, be prepared to wait for water levels to lower, and plan on longer-than-anticipated detours.

“If you do venture out there,” the release says, “remember to Hike Smart NY! Inform loved ones of your detailed trip itinerary, travel with an experienced hiking partner, and pack headlamps, emergency shelter, additional food and non-cotton clothing, along with the rest of the 10 Essentials systems.”
