Geology
Geological setting:
Cover deposits are patchy, varying from bouldery felsenmeer regolith to intermittent till; surface features suggest that the till at this site may be somewhat older than on adjacent surfaces
Patterned ground:
Poorly developed large nets with boulders at edges, but a superimposed pattern of smaller less distinctive nets (c 2m)
light yellowish brown (10YR 6/4) gravelly silty sand; firmly cohesive; moderately developed fine vesicular structure; rock particles moderately stained with smaller particles strongly altered; distinct boundary,
