Geoland
| Rocks on Mt Zanuck are mainly granites, some with very coarse feldspar crystals; on the high altitude northern slopes old cirque basins have till deposits, |
| possibly lateral or terminal moraine, which appear to have remained undisturbed; subsequent glacial activity seems to have trimmed the lower slopes of the |
| Zanuck massif |
