Relict sorted patterned ground in Lesotho

Relict 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...
