Fluvial Architecture of the Lower Cretaceous Lakota Formation, Southwestern Flank of the Black Hills Uplift, South Dakota
From introduction This report describes large-scale depositional units referred to as architectural elements, interpreted from outcrops of three distinct fluvial sandstone units of the Lakota Formation in the southwestern Black Hills area of Custer and Fall River Counties, South Dakota. These fluvial deposits formed near the end of an episode of continental deposition that began when the Jurassic Sundance sea regressed from the region and ended when the Early Cretaceous Skull Creek sea encroached from the north in Albian time.

Landslides in Colluvium
From introduction: This report describes the Delhi Pike area, which is an area of landsliding we believe to be representative of landslides in colluvium throughout the Cincinnati metropolitan area. The area has been the focus of several detailed studies reported in other chapters in this bulletin. The purpose of the report is to describe the physical setting and movement styles of the landslides and, thus, to provide a context for the more narrowly focused chapters that follow.
