Five possible runway sites have been proposed within 4 km of Davis on the northwestern part of Broad Peninsula, Vestfold Hills. Most are on thin, young, sedimentary sequences on low level flat areas, although two are dominantly on Precambrian basement, one of which is at low elevation. This report reviews the geology of each site as a background summary for use by engineers in the event of a decision to build. Permafrost level in the area is normally within 100 +/- 20-30 cm of the surface and appears to vary depending on location and proximity to water masses. The report uses as much information as can be assembled from earlier dispersed reports and adds detailed grain size data from eight sites cored during the 1993-94 summer. Stratigraphy of the sediment sections is not well understood and is best documented in the Heidemann Valley. Maximum sediment thickness known is about 4 m. All sediments appear to be younger than one million years and probably are much younger. Speculation is given about the origin and significance of some of the features of the area.
