Geology
Geological setting:
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
Patterned ground:
Nil
Surface weathering or surface features:
Rock outcrops fragmented with patchy surface staining; carbonate encrustations on some rocks
Soil
Soil parent material:
Fragmented greywacke/argillite; fines possibly windblown
pale yellow to light yellowish brown (2.5Y 7/4 - 6/4) granular gravel; moderately cohesive; moderately developed vesicular structure; many distinct calcium carbonate coatings on rock particles; rock particles angular to subangular and dominantly unstained, 464b rock particles with whitish salt precipitations and distinct thick calcium carbonate
