The one big advantage of this series is that it is complete--has no gaps--a point not to be sneezed at if you have had the common experience of finding that your favorite series has a hole just where you were depending on it to help you, The Geological Survey also hanciles its own two series, called the "mile per inch" and the "2000footer." The first has a scale of 1:62,500, which yields a mile so close to an inch in length that the difference is negligible. This series is printed in sheets about 17x21 inches in size, each covering a quadrangle 15 minutes of latitude and longitude on its sides. The oblong measures about 12xl7 miles in area. Each oblong bears the name of some town, mountain, or lake within it. Local retailers ask about $1 per sheet; if you're in no hurry you can send off to Geological Survey, Federal Center, Denver for their index or key maps and their price lists, generally about 75 cents per sheet. The series has extensive and disgracful gaps. Nearly all Western Oregon is covered, and about a third of Eastern Oregon. A more generous scale, 2000 feet per inch, characterizes the other Geological Survey series. Like the mile-per-inch, it shows land forms by means of b·rown lines called contours. On the who],.e, it is this series that the Geological Survey is pushing nowadays, while the other series marks time. The mappers are going great guns through the wide-open spaces of Eastern Or~ egon right now, and, after having just revised the Puget Sound and Willamette Valley coverage at this scale, are heading west through the Coast Range. This is the series to get, if you can afford it. Prices are the same as for the other series, around $1 per sheet. But where a given area will be covered by only one or two sheets in the mile-per-inch series, it will require four to eight sheets for the same area in the 2000-footer series. The oblongs are about G x 9 miles, or 16 x 23 inches, in area, and the latitudelongitude quadrangle is 7 1/2 minutes on a side.
