Halliday's Bluff and Old Albert Town

This looks across the Clutha to Halliday's Bluff. It intrigued me originally that the bluff gets higher as it gets closer the mighty Clutha River, but I understand that it was an older formation probably when the river ran towards the Cardrona Valley ( The Cardrona River once flowed the opposite way)
U3A talk on Climate Change this morning. I think he had decided that as we were "old" and we would not understand much. Much prefer it when they give you it full blast with lots of information.
