Visual materials, 1961-1990, 2007 and undated

Identifier: Series 8

Scope and Contents

This series primarily contains the slides Longenbaugh created, collected, or used for presentations. The majority of the slides relate to different aspects of groundwater, including artificial recharge, pumping, and well drilling. Some slides relate to his personal activities, including hunting and a trip to Seattle. A large set of slides documents his trip to Peru in 1978-79 and other South American locations. Also here is a small amount of photographs and negatives, most of which were either taken for the Kansas v. Colorado Supreme Court Case or of workshops or short courses Longenbaugh taught. A few of the images, including portraits, are of Longenbaugh. Materials are arranged in alphabetical categories, with the Peru set filed at the end.
