This entry is from information reported by the jumper exiting before her.

He makes note that upon opening he felt extremely turbulent air conditions generated by the waterfall.

In his words you feel some thing is going to kill you and you must fight; the turbulent air was sucking him and he fought until he moved sufficiently away from the cliff where air became stable again. Marita was an experienced skydiver with much more than 3000 skydive and had jumped El Capitan before.

She had a good exit and as the helicopter pilot and guy on top of the cliff said on-heading. So they wondered why she was flying into the tube. She flew through the hole part of the tube, and when arriving at the other side of the cliff, they thought OK, now she gets out of it, but no. The parachute made a left turn at the corner of the cliff and flew up against the wall, this happened altogether three times. At the end the chute collapsed and she slid down until final impact.

The jumpers evaluation was: Marita had a line-twist and when the wind from the left is strong enough it turns your on-heading- chute left into the cliff round (tube).

When you come out on the other side you get the same effect there, the wind goes against the wall,ie makes a round left. When you are still working with the twist you have no chance, it turns you against the wall.
