A few weeks back someone requested GPS coordinates for the Susitna and Yentna Rivers. I have finally had the time to type up the list. These were submitted to the office from a guy that has been coming out here for years and owns a cabin in the area. These are unverified, but I think these could be a great start to help you find your way. LSDA has marked all the trails, so you should be in good shape to navigate. I attempted to break the coordinates up per river, but my knowledge is limited, and I don't have map plotter to verify where all the coordinates fall in order.
