Below is a map of the segments of the Rifle River which were recorded w/ an aerial flyover.  Click on a "map pin" to view a YouTube link of that segment of the river.  The map can be zoomed in/out for greater detail.  More pins will be added as flights are completed.
 

If you spot an area of concern, jot down the time in the video clip and let us know and we can lookup the exact GPS coordinates of that portion of the flight.
