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

Ceiling · Paragliding

Top of the range for paragliding (any rating). Switch wings up top to compare. Hang gliders hold roughly 10 mph more than paragliders.
Undocumented local launch above the South Fork Boise River near Featherville (~4,450 ft); works broadly on E-through-SE flow, with W/NW being the lee side to avoid. Treat it as a thermal site — smoothest early or late, punchy and possibly overdeveloped midday. Rating and access unknown; verify launch orientation and rules with local pilots before flying. All figures are inferred, not from a site guide.
Borderline only 7am–10am — best around 1pm: 11 mph W, gusts 11. All borderline — fly it with a close eye.
