| Approx 4km S of Mt Rich on an extensive undulating landsurface formed by over-riding and retreat of ice from Diamond Glacier; the surface has extensive |
| patterned ground developed on rolling slopes with best development on lower gully slopes; on sloping ground, the polygon troughs have a high scarp face on the |
| down-slope side and a short scarp face on the up- slope side; in many of the polygons, the surface of the soil has a distinct crust; in the patterned ground cracks, |
| there is a greater amount of sandy material; the sample was collected from a crusty patch near the centre of a polygon |
