What we look for at Marmot Hatcher Pass AK

Wind direction

ESE (120°) → SSW (200°)

The wind must blow from within this arc. Direction is the same for both wings.

Ideal speed

5–10 mph

Ceiling · Paragliding

≤ 19 mph base · gusts ≤ 23

Top of the range for paragliding (any rating) — switch wings up top to compare. Hang gliders hold roughly 10 mph more than paragliders.

Thermal site at Hatcher Pass managed by the Arctic Air Walkers, with a flat SW-facing launch that lines up with the up-valley flow. Best in S-to-SW winds at 5-10 mph, and there are multiple launch options around the peak for other directions. The biggest danger is overdevelopment: cumulonimbus regularly tower past 30,000 ft and can suck pilots back into the remote Talkeetna Mountains, so launch early and land before it builds. P2 minimum, P3 for XC; access is via the Fishhook trailhead, with a weather station above launch.
