We were hiking on main trail on a little known side trail that followed a stream up through 7 waterfalls. on the 4th waterfall Vanessa Slipped and tumbled down the face of a 60 foot waterfall landing unconscious in shallow pool. Cell phone reception was sketchy and we couldn’t get continuous service with 911.  I turned on my PLB.  When we could finally get a strong enough signal. SAR informed us that they had gotten our coordinates from the coast guard because of the PLB and that a helicopter was on the way.  It arrived 10 minutes later.  Vanessa was taken to hospital and released 7 hours later with 2 broken wrists and 21 stitches across her face.  It would have been impossible for her to hike or us to carry her out.
