STRATAGEMAGE FONT

In order for the geologic-age characters in the EPS files for this section to display and print properly, you will need to have the geologic-age character font StratagemAge installed in your system folder.

We have provided both a Macintosh and a Windows/NT/UNIX version of the font for your use.  To download the font, return to the main page and then click on the appropriate link.



CUSTOM COLOR PALLETES

As an easy way to assign color to geologic map units, custom color palettes have been designed to replicate the colors shown on the chart showing Suggested Stratigraphic-Age and Volcanic Map-Unit Colors (Section 33). The CMYK (cyan/magenta/yellow, with K = 0) color combinations shown on this chart have been used for many years on geologic maps published by the U.S. Geological Survey.

The custom color palettes were created in Adobe Illustrator 8.0.1 on a Macintosh and saved in Illustrator EPS format. Note that some colors can only be distinguished from one another on monitors that can display 16.7 million colors.
