The Jackrabbit Trail from Rock and River at the Keene end is skiable to the top of McKenzie Pass above Whiteface Inn Lane. Given that Saranac Lake only received 4" of snow, a descent to McKenzie Pond cannot be recommended.
The Ausable Lake road is being driven, but there is plenty of skiable snow next to the vehicle tracks, and there is a skied in track for the first mile from the gate. Please extend it and keep the tracks as wide as the ones on the first mile.
Tuesday's big storm did not dump quite as much snow as predicted on the Jackrabbit Trail or the High Peaks in general. 4" in Saranac Lake, 6" in Lake Placid and Keene. The north end of the Park and up to the St. Lawrence River did get nearly a foot. Nevertheless, there is enough snow to ski the golf courses and the truck trails and no danger that this will melt before the weekend. In fact, it will be more like mid-winter temperatures through the weekend before it warms up into the 40s to start next week.
In the High Peaks, the snow does not yet reach the 12" threshold where regulations require snowshoes, but travel is generally easier with snowshoes if there is more than 6". And as noted above, it will be full-on winter on the higher summits with goggles, face mask, and of course traction for any of the higher, steeper trails. No report from Lake Colden, and no lake ice is anywhere close to safe.
For skiers, here is my current speculation about possibilities. No idea how much blowdown might still be down after the Halloween storm. More on Friday.
Marcy Dam Truck Trail: Skiable to Marcy Dam. Be aware that there are rocks that, while covered, present a hazard.
Hays Brook Truck Trail: Enough snow to be skiable, but there may be blowdown.
Fish Pond Truck Trail: Same as Hays Brook.
Raquette Falls: First few miles skiable, but not enough to ski to the falls.
Ausable Lake Road: Still likely being driven, so not a good surface for skiing.
Newcomb Lake Road: Likely skiable, but the remote monitoring equipment at the Huntington Forest is not updated. Reports of conditions welcome.
