Abstract

A dilemma in engineering geologic mapping is how to provide the greatest amount of useful information in the smallest space and in the most visually logical format. Stratigraphic columns, traditionally used to show strictly geologic information, may be adopted to address engineering and hazard identification concerns. Columns can be constructed to show fracture density, rock mass rating, resistance to weathering, soil development, water flow, and other useful parameters for rock cuts, tunnels, foundations, and aggregate potential. Each column summarizes the anticipated engineering behavior of a given vertical section of the local bedrock, and this behavior may be extrapolated, with due care, to other locales where the same section of rock is present. We have used engineering stratigraphic columns for several years as teaching tools (Santi and Gregg, 1999), but they can also serve as concise local or regional reference tools for engineering geologists, much as traditional geologists reference standard stratigraphic columns.
