Old till persists on even higher levels of Ackerman Ridge; the lithology is mixed however with argillite as well as granite; indications of greater age include more advanced |
surface weathering and more salt accumulation |
Scattered small snow patches; weak soil crust in places suggests occasional surface |
moistening |

SURFACE FEATURES |
Black argillitic rocks have strong surface polish; granitic rocks are well stained and many are crumbled; no staining on undersides of surface clasts indicates |
surface stability; salt accumulations beneath some surface clasts |
