Beacon and Ferrar rocks were studied just west of the Dry Valleys, between the Skelton Neve and the Mackay Glacier area. Detailed stratigraphic sections were measured with staff and level at Mistake Peak, Shapeless Mountain, Skew Peak, Mount Bastion, Robison Peak, Mount Fleming, Mount Feather, Mount Warren, Escalade Peak, Swartz Nunatak, Mount Kempe and Rotunda. Collections of rock samples were taken for petrographic description and analysis from all sections measured. Fossils of leaves and stems from the Permian and Triassic coal measures were collected. Glossopteris leaves up to 40cm long with veins clearly preserved were found at Mt Fleming and a varied collection of well preserved calamitid stems, ginkow and fern like fronds up to 50cm across were recovered from a locality at Shapeless Mountain. In addition, Glossopteris and Gangamopteris leaves were found in shale that graded down into the uppermost glacial beds 30cm below. Dating of the carbonaceous beds was attempted from samples of fossil pollen and spores. Further geological data was gathered for the compilation of a 1:250,000 map of the Mount Harmsworth 'Quadrangle' and samples were collected from the rhythmically layered Mount Warren intrusion to continue studies on this unusual feature.
