Located near Jefferson, CO, at the northeastern end of the south park basin, in Park County. Although this H2/P2 mountain site appears gentle and forgiving, conditions can change rapidly leading to dangerous flight conditions for both PG and HG (quickly becoming H3/P3+). The site sits at the top of the South Park basin and valley flow patterns (northerly/upslope conditions during daytime heating and southerly/downslope conditions) are the normal. Prior to flying this site, a thorough understanding of valley wind systems, wind compression, and thunderstorm hazards is highly recommended. Early morning conditions are mild.
The site is good for HG, PG, and MW, and pilots learning mountain flying specifics. This is a high altitude site, solid and aggressive launch techniques required.
