Bellyache Ridge

• Wind directionE (90°) → SSE (160°)
• Ideal speed3–10 mph
• Upper limits≤ 15 mph base · gusts ≤ 20

RMHPA (USHPA chapter) site guide gives explicit data. Bellyache faces NE-to-E; a consistent MORNING site driven by katabatic (drainage) flow off the Continental Divide producing an easterly wind. Working direction: SE early morning trending to NE-NNW late morning; all other directions unfavorable. Ideal speed ~7 mph (morning winds typically 3-10 mph); usable range 0-15 mph; guide notes a low max gust (~5 mph) for safe smooth conditions. Flyable roughly 7am-11/12 (4-6 hr window) before the prevailing west mixes down by noon and ends flying for the day. Ridge soaring possible before ~8am on the katabatic flow; thermic/XC potential develops later in the morning. Hazards: high-altitude/turbulent conditions; Interstate I-70 and a 2-lane highway to the north; high-voltage power lines and a rushing river that must be cleared to reach the LZ with NO BAILOUTS. Needs a solid forward launch for light wind. Rating: P2/H2/M1 minimum (P3/H3/M3+ recommended for mid-day thermic conditions). Access: USHPA + RMHPA membership required; private property, respect gates/fences. Min glide 3.2, smallest wing 12 m.
