Geoland
| The Ellsworth Mountains comprise a thick sequence of folded metasedimentary rocks comprising limestones, conglomerates and quartzites dating to |
| Precambrian; the West Antarctic Ice Sheet is believed to have fluctuated greatly in response to global sea level changes and evidence of these fluctuations should |
| be present in the tills and soil weathering record; the Meyer Hills are predominantly quartzitic sandstones |
