Conditions

Ideal is SSW wind, but this site is most often used when Marshall is not flyable: Weather stations at launches (Crestline + Marshall Peak) and LZ.
Dusty Rhodes, 2017/3/26: OK to launch when up to 40 mph North wind at Crestline. It is best when flown at 3 pm or after (not noon), when wind gets organised from the valley. If the winds are enough to ridge soar, do not launch it is rotor. You just want a 5 mph breeze.

By order of interest:

• Forecast:
  • Windgram, for wind direction and altitude ceilings: FlyMarshall. Understanding "Wind Barbs".
  • RASP (Regional Atmospheric Soaring Predictor) for Southern California: Soaring Predictor (Older version). Typical sequence:
    • Select day and time.
    • Select a parameter like "Sfc.Wind (10m)".
    • To change the opacity of the data layer: Click the "+" or "-" icons in lower right (Old version: Use slider in the upper right, or mouse's center wheel).
    • Finding flying sites: Click the layer icon in the upper right, enable the "Sounding/SkewT". Hover your mouse pointer over the markers, names appear.

Description	Latitude	Longitude	Altitude (ASL)
Santa Ana river dam LZ area	N 34.1025°	W 117.1073°	570 m	1869' (Approximate, from Google Earth)
Spine launch	N 34.1188°	W 117.1126°	963 m	3160' (Approximate, from Google Earth)
Bump launch	N 34.1196°	W 117.1106°	1026 m	3365' (Approximate, from Google Earth)

• Spine launch. Google Maps.
• Bump launch. Google Maps.
  Directly up & behind "Spine launch".
  Better than Spine launch: You don't get switchy winds from either side of a spine.
  About 350' hike up, taking 17 min. The trail path (Image from Google Earth) starts (Location in Google Maps) from the road, lower than the Spine launch. Trail shown in video section.

For a great way to explore this flying site in 3D, see Google Earth's Local points of interest in the Maps section.

Shuttles / Navettes

• If you see me (guy in orange flight suit) or my car (White Subaru Outback) ask me for a ride up.
• Lua. 310-404-4750, call or text. More info: PG and HG. Has a truck and a van available if needed. Can also drive you and your car up to launch and have it at the LZ for your convenience.
• Troy. 951-202-7037. Will drive you up in your car, or his SUV.

Insurance / Assurances

• You will need to become a USHPA member and it's not expensive for the 1 month membership. Just contact one of the Schools so you can take the one month membership for 10$. It is good all over the US for the 30 day period.
• Tu devras devenir un membre de l'USHPA et ce n'est pas cher pour être membre pour un mois. Tu as juste à contacter une des Ecoles afin de prendre le membersip d'un mois pour 10$. Ce sera bon pour tous les sites aux Etats-Unis pour une période de 30 jours.
