Tall crow, have you had any luck tracking these down yet? I'm also interested in getting some nautical maps for this area. I can probably guess what you need then for. I'll be in S.E. during may 2018. PM me if you drew a tag.
Here's a link to a place that will sell you charts. https://www.westmarine.com/search?Ntt=charts Make sure you know what you want-if you aren't sure ask. Charts are tricky. By that I mean you can get a very general chart without a lot of detail or you can get detailed charts. Most of SE will have detailed charts available. This link may show it better than I explained it- https://www.nauticalcharts.noaa.gov/catalog/images/2014Alaska.pdf Have fun
