I have scanned my copy of Southern Exposure: A Climber’s Guide to Oklahoma and added it to the website for download. You can find it under the new Guides page.
This is the first guide to Oklahoma climbing and still a valuable resource. Though it doesn’t say in the guide itself, I believe it was published in 1980. Written permission was granted by one of the authors, Duane Raleigh, to make the guidebook available to the climbing community as a downloadable/printable file. Enjoy.
