Northern Lynn Canal topo mosaic

Description

12 USGS topographical quadrangles (1:63K scale) melded into one large map and printed in 3 vertical overlapping panels for wall display. This makes a wall map of a bit less than 5 feet by 5 feet (1.5 x 1.5 m). Note: the USGS has not gotten around to updating the topographical maps for this areas for a while: most of these maps were made between 1948 and 1954 with “minor revisions” in the 1960s! Obviously there have been a few changes in the human landscape (surprisingly small because most of the map area is undeveloped, and the inhabited areas have not grown too much over the years), and the physical landscape (such as glacial retreat, silt deposition, and vegetation changes). Also, the mosaic is made from scans of paper maps and the quality of some of scans is less than perfect and/or not exactly consistent from one map to another. Despite all this, the end results looks pretty good, partly because I spent a lot of time working on it with Photoshop. There are a couple areas where the colors shift a bit from one quad to the next but it is not distracting, in my opinion.
