Mount Rainier Volcano Hazards Map
Dear Sir - I work as a scientific illustrator for the USGS - Cascades Volcano Observatory. We are the authors of this map, in its myriad forms. The map "explanation" or "legend" that you have included does not explain the light orange color you have used. This orange color appears near Puget sound and Tacoma - along the shoreline and you also feature this color near Enumclaw, Eatonville, Buckley and Auburn.
Since I am intimately familiar with this map and the contents - I immediately noticed that these orange areas do not correspond to our official versions here at the USGS. So, I am writing to you and hoping you can clarify the meaning of the orange areas? I realize that not everything that appears on Wikipedia has been vetted, however an accurate portrayal of scientific information is important. This information, if inaccurate, should be corrected...
