John B 106 Posted March 26, 2014 Share Posted March 26, 2014 Salt Springs on the Northern side say about 1/3 of the way between the light and Gardiner gap...Why is that point called that ? We were wandering around there last weekend, but apart from looking at the beacon we didn't see anything remotely spring like . and what is the beacon for ? Quote Link to post Share on other sites
Marshy 30 Posted March 27, 2014 Share Posted March 27, 2014 Potentially to do with the salt works they had there in 1890's? Quote Link to post Share on other sites

John B 106 Posted March 27, 2014 Author Share Posted March 27, 2014 I knew that area was a saltworks( around Mckenzie) and we have the saltworks buoy to the south of rangi light. ( as opposed to the salt springs land beacon to the east of Mckenzies.) I'm just curious as to the reason for the salt springs and wonder if its literally a salt spring. I suppose logically if salt water is pressurised up there through a lava cave/ tube, it'd be a good feed for salt pans. Or, I suppose you could imagine a freshwater spring at the saltworks being called that too. Sorta connected I went through a reseach phase about the wrecks in Wreck bay some years ago. ARC used to have a great web page on them but thats gone now. One was an American 4 masted schooner which came here, became a coal hulk and then a nightclub . Columbia. ( or Showboat when it was the party boat) It was sabotaged and sunk twice before being run aground and burnt at wreck bay. a bit of reading here ..http://timespanner.blogspot.co.nz/2012/ ... baret.html Quote Link to post Share on other sites

Guest Posted March 27, 2014 Share Posted March 27, 2014 Nope, it's actually shot from a video presentation up on North Head. It's Rough Rock before it was blown up Quote Link to post Share on other sites

John B 106 Posted March 27, 2014 Author Share Posted March 27, 2014 I can't quite get that, it is really rocks, not a tow of logs or something? oops I see the answer now. I never knew that. "Waihau" is the name that rolls around and pokes the inside of my skull when I look at the boat. Quote Link to post Share on other sites

waikiore 398 Posted March 31, 2014 Share Posted March 31, 2014 You been spotted hanging round the Mckenzie Bay area a bit lately JB have you found treasure in one of the wrecks on wreckers row?? Quote Link to post Share on other sites
John B 106 Posted March 31, 2014 Author Share Posted March 31, 2014 Hahaha, yeah walking around salt springs whetted our appetite for a stroll around the fields at coastguard. lava fields that is.We like to do that once every decade or so. Big weekend, out to drunks for sat night, back to westhaven for kids and a day trip first thing sun morning. Two trips up the washing machine on sunday.. two! ( one set on delicate, one on agitate and spin) at coastguard I even got a tour around a certain well known crew.org short handed boat which has just changed hands.

Zozza 293 Posted April 3, 2022 Share Posted April 3, 2022 Surely the big question is....what do the computer models show what happens when Rangitoto blows itself up again....it is a case of 'when' not 'if' from what I have briefly read on the subject. Hope I am somewhere northward on my boat when that happens as will be like a mini atomic bomb hitting Auckland when it does happen. Quote Link to post Share on other sites
Jon 359 Posted April 3, 2022 Share Posted April 3, 2022 I’ve been told that all of Auckland’s volcanoes are monolithic (only erupt once then move on ,nothing to see here) So going north may not help, the average time line between Auckland eruptions is 600 years and the last Rangi was 900 years ago. So if we could have the next one on a cross of Tiri - Channel and Little Barrier - Durville would make an ideal racing mark and ideally with a harbour on the east and west would be great too. 2 Quote Link to post Share on other sites

eruptn 95 Posted April 4, 2022 Share Posted April 4, 2022 Thanks IT for reading .... The attached image is from a paper dating events in Auckland ... eruptions started about 140,000 yrs ago and last was Rangitoto (600 yrs ago). Locations are random (oldest and youngest are basically next to each other. The rate of eruptions has changed with time, but was really busy around 30,000 yrs ago (an average rate means very little). As mentioned all the volcanoes have erupted once, except Rangitoto which has erupted twice (the 1st maybe about 6,000 yrs ago). Eruptions are very unlikely to occur outside of the area shown on the map (left side). Where next ... toss a dart at the map ...
