Not quite sure how it happened I went down at the top of the hill. By the time I reached her it was to late.
She said she went off a big roller and got forward and cartwheeled or slammed on her arm some how or she may have tried to catch her fall I don't know.
Not happy with myself. Not sure if this was to much to soon. She has riden this feature many times. Kinda a large high roller that doesn't really shoot you up but if you carry to much speed not sure, again I only saw the after math.
