Every published report, grouped by sector and then by the block it belongs to. Reports that are written but not yet scheduled are not listed here — this page only ever shows routes you can read today.

01

Laurentides

The Laurentian shield north of Montreal, where rounded gneiss domes collect a deep, wind-packed snowpack from December into April. Trailheads sit between 300 m and 500 m, so the base here usually runs 20-40 cm deeper than the St. Lawrence valley floor. Mixed hardwood below 600 m, black spruce and balsam fir above.

02

Adirondack High Peaks

New York's 46 High Peaks sit inside a state constitutionally protected forest preserve, which is why the access roads stay unplowed and the trailheads are further from the road than almost anywhere else in the northeast. Snowpack runs continental: dry, faceted, and prone to persistent weak layers on north aspects.

03

White Mountains

New Hampshire's Presidential and Carter ranges generate their own weather, and the notch roads that reach them are the windiest plowed corridors in the northeast. Above treeline the snow is stripped and re-deposited into slabs; below it, sheltered valleys hold some of the deepest snow in the eastern United States.

3 routes · Pinkham Notch · Bear Notch Forest Roads

04

Gatineau Park

A 361 km² federal park inside the Ottawa commuter belt, which makes it the most heavily winter-used terrain in this guide. The park grooms about 200 km of ski trails and leaves the rest to snowshoers; the Eardley escarpment gives it 200 m of relief in a single step.

4 routes · Luskville Escarpment · La Pêche Lake Block

05

Algonquin Park

Ontario's 7,653 km² interior park, sitting on the transition between Great Lakes-St. Lawrence forest and boreal forest. Highway 60 is the only plowed access, which leaves everything beyond it as a genuine winter backcountry. Snow depth on the interior lakes peaks near 90 cm in late February.
