Samples from pits, surface rocks, stones and from outcrops were collected for examination and analysis to determine the processes which quartz grains from the Beacon sandstone have been through before being deposited in the tills which they were sampled from. The first pit was located on lower level moraine on Aztec Ridge immediately above the western wall of Beacon Valley and excavated to 24 cm. Three sites in New Valley, immediately east of New Mountain, 12-14 km west of Aztec Ridge were sampled with pits excavated 1.7 m, 1.2 m and 0.7 m deep. Surface rocks, stones and samples from outcrops were collected in the near vicinity to the pits.
The Ross Sea Region Soils database, run by Landcare Rsearch, New Zealand, stores information on soil site and soil pit horizon data from 35 years of soil studies by the investigators and their associates. There are >900 sites in the database but they are currently not sorted
The existing soil samples (Site 673-696,703-704, 736-755, 757-761, 780-781, 833-844) have been sorted and stored at the Institute of Geological and Nuclear Science, Lower Hutt, New Zealand. All soil records are on the Ross Sea Region Soils database, Landcare Research.
