Location: | 562278. 13 kilometres east of Aberfeldy. | Jointed basalt - Mount Useful. |
Access: | Mount Useful Spur Track. | |
Ownership: | Crown Land. | |
Geology/Geomorphology: | Mount Useful is capped by Tertiary Older Volcanics. This basalt forms cliffs up to three metres high on the eastern and south-eastern side of the mountain and these cliffs display prominent columnar jointing. The basalt overlies a silica cemented conglomerate which is exposed on the Mount Useful Track. | |
Significance: | Regional. Exposures of the quality of this basalt outcrop are uncommon in the highland section of the study area while silicified pre-basaltic sediments are rare in the study area. | |
Management: | The columnar jointed sections in the basalt should be preserved. Track widening and extension, or limited quarrying on the western slopes of the mountain would be consistent with the maintenance of the site. |
