Abstract
AbstractRelict sorted patterned ground is described from an upland interfluve on the Lesotho‐South Africa border at an elevation of 3280 m a.s.l. The site comprises 2–4° slope angles. Frost penetration through the regolith is inferred to have been to 1 m depth during pattern formation. Sorting is thought to have resulted from deep seasonal freezing during the depressed temperatures of the Late‐Pleistocene Last Glacial Maximum (∼18 000 years B.P.). No direct evidence for permafrost is documented. Copyright © 2004 John Wiley & Sons, Ltd.
