Site Details

Located on the eastern side of Riffe Lake and near the towns of Morton and Glenoma, Dog Mountain is the most popular hang gliding site in western Washington because of the consistently soarable conditions throughout the year. Once above launch, pilots enjoy spectacular views of Mt. Rainier, Mt. Adams and Mt. St. Helens.

Dog Mountain is a privately owned site, and all pilots must be current USHPA and CBCC members to fly it. Additionally, the landowner maintains a locked gate at the bottom of the access road, and pilots must obtain a key and sign a waiver each year.

Cloudbase Country Club’s “home” site is H-2 friendly, especially now that the Dogpatch landing zone is accessible year round, but novice pilots must be accompanied by a H-3 or higher rated pilot mentor who can explain site protocol and potential hazards.

  • Due to launch topography and rotor behind launch, P3 with solid restricted launch skills is required at a minimum.
  • Launch is challenging for PG with an obvious sharp break-over from the launches to the staging plateau. Strong ground handling and canopy inflation skills are needed to avoid trees in back and to the sides of launch and to account for consistent rotor behind the launch breakover.
  • XC is unlikely due to topography and weather. Experienced pilots need to use their ground and sky reading skills if they choose to leave the ridge soaring bands on the west faces of Dog Mt.
  • Venturi is to be expected to the sides of any wind-facing ridgeline.
  • If crossing Riffe Lake, pilots need to pay attention to the mid-lake venturi effect and be aware of potential air traffic over the lake.
  • Rotor may be encountered below west launch due to the (very obvious) tree line.
  • North launch may have right cross winds and rotor if launching outside published wind direction/speed recommendations. Cross winds are obvious when observing vegetation at and below launch.
  • The site is inappropriate for mini-wing launch.

    Only launch within your rating and skill levels; When in doubt, don’t set up or launch.

    If you’re in the air and the sky starts to look threatening, get out of the air immediately. Also be aware of nearby terrain and potential for rotor. (Yes this is common sense H1/P1 stuff and we feel silly for needing to say it, but rest assured it’s here for a reason!).

    All incidents should be documented via the current USHPA incident reporting protocols with a courtesy copy to the site contact. Any incident involving non-pilot property damage, injuries or assistance from non-pilots(EMS, police, public bystanders etc) must also be reported as soon as practical to the site contact.

    In an emergency, Call 9-1-1 first.
