| Michelle_0048 | Oxylates and sulphates are formed from the weathering of the overhanging pyrite/carbon rich phyllite. Acidic water leaches through bluff and constantly deposits salts on rock face and soil below. |
| Michelle_749 | Oxalates and sulfates are formed by the weathering of the overhanging pyrite/carbon rich phyllite of the Anakeesta Formation. Acidic water leaches through bluff and constantly deposits salts on rock face and soil below. |
