Alaska River Guide (9780882404974);1993, p19
The article deals with the topographic maps of rivers used in the book "Alaska River Guide." Rivers change their courses--particularly where they discharge into the ocean, forming wide deltas and sloughs--and the topographic maps made in the 1950s and 1960s may be incorrect. Newer maps have mostly just been updated with land status changes; for example, national parks and refuges are shown. But only some of the newer maps in the scale 1:63,360 have the water features revised. Topographic maps listed for each river in this book are in the 1:63,360 series.
