No dedicated site guide found. "Centennial Ridge" near Centennial, WY (Snowy Range / Medicine Bow National Forest) is NOT listed in paraglidingEarth, Wilder Adventures' Wyoming launches, XContest, or any USHPA/club guide — it appears to be an undocumented backcountry/thermic launch. Wind window below is INFERRED from the paraglidingEarth orientation hint (NE, E, SE octants) plus general high-mountain ridge knowledge. Ideal arc is the E-facing core (~045-135, wind FROM); marginal edges (~022-045 and ~135-157) become increasingly cross. At 9478 ft MSL the air is thin: true ground speed feels stronger than the indicated mph, so keep base wind conservative (light cycles, ~5-13 mph) and treat 15 mph as a hard cap with gusts under ~18 mph. Classic high-Rockies thermic site behavior: morning calm, lift builds late morning, midday/afternoon overdevelopment, strong thermals, and gusty/switchy cycles; best window is typically mid-to-late morning before convection and valley winds turn the launch turbulent. Watch for lee-side rotor if the gradient backs to W/SW/NW (off the back of the Snowy Range), venturi/strong gradient on this exposed high ridge, and rapid afternoon build. Likely advanced/mountain-experienced access (high alt, no school/tandem operations in this part of WY). Verify direction, footprint, and legality on-site or with local pilots before flying — figures are estimates, not a vetted site guide.
