| They are marked by eruptions of cooler, stickier lavas such as andesite, dacite and rhyolite. |
| These are overlain by flows of rhyolite, dacite, and andesite totalling about 900 m in thickness. |
| The canyon is carved out of dacite, and there are some large trees with yellow and green leaves. |
| It comprises a series of ridges and vertical towers of dacite that cut through the centres of the older Mount Fee units. |
| Here colorless to yellow crusts of mimetite coat open spaces and coarse fragments in brecciated dacite. |
| These are called tension gashes and formed as the dacite split open allowing the quartz fluid to fill in the cracks. |
