Mount Victoria. 
333 
Hartley, with abundance of Spirifer, Pro - 
ductus , Gonularia , and Fenestella, etc. 
7. Very interesting beds and bands of ironstone 
are exposed in the railway cuttings at Mount 
Victoria, and better still near Katoomba. 
The almost parallel and wavy lines are due 
to the alteration of ferrous to ferric iron. (See 
page 116.) 
2. A few geological trips from Mount Victoria : — 
1. To Bonnie Blink for Upper Marine beds. 
Good road for vehicle. Distance 4 miles. 
2. To Cox River. Granite may be seen in great 
varieties, graphic granite, porphyritic granite, 
etc., also typical diorites and Devonian beds. 
Distance 9 miles. The greater part of the 
road is fit for vehicles. 
3. Hartley Vale, distance 7 miles along a good 
driving road, Kerosene Shale Mines. 
4. Grose Valley, distance 6 miles, bad driving 
road, coal seams and kerosene shale. 
5. A walk down to the base of the hill, Hartley 
Road. The Hawkesbury and Narrabeen 
beds can be examined, and the Permo-Car- 
boniferous and Granite lower down. 
6. An interesting trip can be made to an igneous 
intrusion in the valley, near Springwood, or 
in another direction to the Devonian beds 
exposed in the railway cutting just beyond 
Rydal, and from there to the summit of 
Mount Lambie.
