I told you it was gonna be awesome, once Russ gave the word it was in process!
Use a more advanced graphic software, such as Adobe Illustrator, which stores the image in a "vector based" format, instead of Paint which stores images as a grid of squares (bitmap). Text in a vector format is stored as the actual text, with a font size and style, and a position where the text appears, instead of as a bitmap grid at a fixed resolution. So when you zoom in on a vector graphic, the viewing software (such as PDF viewer) will redraw the text at your full screen resolution.
Of course converting the original graphic to a vector software involves some tools/work. It's not a 60-second "press one button" operation. Although some tools like "Live Trace" do a fairly quick and decent job. Greg has higher standards than that, though.
[edit:] Oops. Thanks for the spelling/usage correction.
I see Sierra translates to "saw", so the teeth are already plural.
Or would you think of each little mini-range (like Palisades) as a separate Sierra?
