• Upper limits≤ 18 mph base · gusts ≤ 22

No explicit club/USHPA numeric wind guide was found for Alberton. The site appears in the paraglidingEarth database (takeoff ~1741-1756 m, matching the 5738 ft elevation) but with no populated text description, and the nearest active chapter (Missoula Hang Gliding & Paragliding Club / Glide Missoula) lists Mt. Sentinel and Mt. Jumbo publicly but not a detailed Alberton site guide. Wind window therefore inferred from the paraglidingEarth orientation hint (NE, E, W, NW) plus general ridge/mountain-soaring knowledge. The hint indicates a multi-aspect launch: an easterly arc (roughly NE through E) and a westerly arc (W through NW), with S and the SE/SW quadrants NOT working. Treated easterly (~045-100) as the primary/ideal arc and the westerly side (~280-340 / W-NW) as a secondary working arc usable when valley/thermal flow favors it; both edges are cross/marginal. Ideal speed ~6-15 mph, base max ~18 mph, gust ceiling ~22 mph for typical mountain free-flight at high elevation (true airspeed/penetration is reduced at 5700+ ft, so keep usable speeds conservative). Likely a thermic, high-desert/montane site near the Clark Fork / I-90 corridor west of Missoula where strong afternoon valley winds and convergence are possible; watch for rotor/lee turbulence when wind comes off-orientation (S/SW), overdevelopment, and strong mid-day thermals. Best flown morning glass-off or mid-to-late afternoon thermal cycles depending on the day. Rating/access unknown - verify launch permission, rating requirements, and current conditions with the local Missoula club before flying.
