INDEX TO PUBLISHED GEOLOGIC MAPPING IN OREGON 1898-1967

Published geologic mapping in Oregon had its beginning in 1898 with J. S. Diller's Roseburg folio, which was issued by the U.S. Geological Survey. This map was soon followed by the Coos Bay (1901) and Port Orford (1903) folios, also by Diller. Since that time, more than 225 geological and geophysical maps in Oregon have been completed, which has necessitated peri odic revisions of the first index map, which was published by the Department in 1940. More than 100 geologic maps have been issued in the past eight years!

Although all of the earliest were the products of the U.S. Geological Survey, in 1914 maps and reports began to be issued by the Oregon Bureau of Mines, predecessor to the Department, and by 1940 they were being published by colleges, scientific organizations, and various pub lic agencies, as well as by this Department.

For the sake of clarity, the information presented in this latest series is arranged on six index maps, as follows: 1) geologic maps published in The ORE BIN; 2) ground-water and engineer ing maps; 3) geophysical survey maps; 4) geologic quadrangle maps; 5) miscellaneous geo logic maps, 1960 through 1967; and 6) miscellaneous geologic maps published prior to 1960. We have also included an index to topographic quadrangle maps, Army Mop Service sheets, and geomorphic divisions .

The most important a~eal geology project being conducted in Oregon at the present time is the State Geologic Mop. The geology of the western half of the state was published in 1961. Since that time the Department, in cooperation with the U.S. Geological Survey and aided by university professors and graduate students, has been continuing this study in the eastern part of the state. Most of the field work for this project has now been completed, and it is expected that the final map will be ready for publication within the next few years.
