Subject was in a very remote
area of Coconino county. We were about a mile south of
the Chevelon Canyon Lake. FS 169 is one of the roads we were
on.At the trail head the altitude was
7,100 ft. Subject was 600 ft below this with a severely
broken ankle. It was determined it would be easier to lower
subject to the bottom for a helicopter ride to the
hospital. The trail was very steep so rescue members tied a
rope to the litter and wheel to belay the subject with
a Munter hitch. 
The Munter hitch is simply a set of wraps using a rope or
cord around an object, generally a round object like a pipe,
pole or more commonly, a carabiner. Its main use is as a
friction device for controlling the rate of descent in belay
systems.
This was a good effort by all who assisted
in the rescue.
