No club/USHPA site guide with explicit numbers was found for "Phipps" as a flying site. Phipps Park sits on the high south-facing bluffs/rimrocks on the southwest outskirts of Billings, MT (elev ~3825 ft MSL). Wind window inferred from the paraglidingEarth orientation hint (S, SW octants) plus the SW-facing bluff terrain. Ideal arc ~S-SW (180-225 deg, wind FROM), with marginal/cross edges out to SSE (~160) and WSW (~250). Beyond that the lift goes cross/leeside. Assumed moderate ridge-soaring speeds: ideal 8-15 mph, max usable base ~18 mph, gusts to ~22 mph; above that expect overpowered/turbulent conditions over the rim. HAZARDS/UNKNOWNS (unverified): potential rotor and venturi/thermal turbulence off the rimrock terrain; high-plains thermal cycles can make midday rowdy, so smoother sled/soaring conditions are more likely morning or evening (glass-off). Rating, official launch/LZ, and access permissions are UNCONFIRMED -- contact the local Billings/Montana free-flight community before flying. Treat all numbers as rough estimates pending a real site guide or pilot report.
