I hear...
Internal compound fractured lower jaw and two upper facial orbital fractures, plus I would guess, a probable broken nose = horrific face plant.
Heard it from the fire department guys who went in from 8th street TH. They have her bike. Accident was near the top. Medics went in from the Clarermont TH.
She was lucky to be easily accessable. Her friends weren't sure exactly where they were so couldn't give the best access, which is a big issue with rescue efforts. Patient location is obviously pretty important for quick response.
Only Ada Co. sheriff has motorcycles for quick patient location. Medics may have ATV's, but they are real slow to break out, so usually walk. Boise fire dept. walks.
Bottom line. Don't crash, but if you do, crash down low in the foothills. The further you are up into the hills, the longer the response time and greater the need for more accurate patient location.
Having been involved in a few foothill responses, the responders are always looking for information from the users in the immediiate vicinity and any help that a person on a bike could give, like possible access. Cell phones work in the foothills and should be carried just for this reason. Having good knowledge of the trails and even an altimeter for elevation helps zero in on the patients location.
A lot of Boise firemen bike and know the foothill trails system pretty well, so we usually figure out where the patient is pretty fast, but not always. Mountain bikers have been involved in quite a few rescue efforts by often being able to pinpoint patient location as they descend and directing emergency response personnel to them.
Rescue out of upper Shingle creek would be fraught with difficulty. Same with Dry creek.
Cell phones don't work in there, but they would 500 feet up on the hillside.
What would your best course of action be? Not something I especially want to have to think about as I speed down through the winding curves and multiple creek crossings of Dry creek.
