Try this link above. The waypoint files were very accurate. I just got off the Green River (today) from Ruby Ranch to Mineral Bottom. The river is still high with limited campsites. If you choose your camps wisely, you may avoid being eaten alive by mosquitos. We were self supported in IKs. We did the trip in 3 days because we had very limited time. It was hot, 100 plus degrees in the day. We spent a fair bit of time in the river. Copious quantities of sun screen and effective bug repellent are essential. Our trip was driven by our search for tolerable camp sites. There were things that we wanted to see that we passed because of the bugs and of difficult access.
The Tamarisk trees are definitely being quickly destroyed by the beetles. There are many places where native vegetation has re-established itself.
We had a short but pleasurable trip.
