This GPS cache was located in the Lane Cove National Park, in the lower-north suburbs of Sydney, NSW, Australia. It was Australia's first cache, planted 18th May, 2000. It has now become a "virtual cache" because of its unfortunate position (please read below!!!). DO NOT GO TO THE EXACT SPOT. There is nothing to see, and with the cache removed, and 7-metre accuracy, I can't even recognize the exact spot myself.
Note that it is illegal to plant caches in national parks without permission. Something which should be obvious, but the sort of people who would hang around a newsgroup like sci.geo.satellite-nav are not necessarily experts at the bleeding obvious, unlike Sybil (ref: Fawlty Towers).
This spot was chosen because it was believed to be remote and uninteresting, so that no-one would ever stumble on it by mistake. Unfortunately, life isn't that simple. Some places in the park have been designated as remote places suitable for growing rare plants. I managed to place mine where they were growing Darwinia Biflora. Secondly, people normally stick to the walking tracks (as they are supposed to), rather than heading into the scrub. So placing the cache there provides unexpected attention to some normally undisturbed scrub. Thirdly, your shoes carry weeds from one place to another, and with cache hunters arriving from unexected directions, this causes unexpected problems. Fourthly, during bushfire season, backburning may be done, and the rangers need to know of unexpected people before they commit homicide! :-)
However, history can't be changed, and these are the coordinates of Australia's first geocache, and people still regularly go to it. Some consider it to be the Mecca of Australian geocaching, and indeed, it was the site chosen for the Australian gathering of the 10 year anniversary of geocaching.
I think there are a number of entrances to the National Park, but the one I used was at S33 47.5649 E151 09.3768. As of 2010, it costs $7 to enter the national park with your car. I have also been informed (could someone please verify and let me know more details like the coordinates of the entrance to the park?) that there is free parking at the end of Plassey Rd (S33 47.333 E151 08.570) allowing you to walk (5 minutes) into the park for free. There are toilets and BBQ facilities in the park. I do hope that if you visit the park, you go to some of the nice areas instead of just the cache. The cache was deliberately hidden in a non-descript area and I hope this is not your only impression of the park!
The cache's position was averaged for about 30 minutes so has an estimated accuracy of 7m.
Since this cache is now virtual, please email me with the answers to the following questions:
1. How close can you get to GZ without leaving the track that goes around it? [hint - this also doubles-up as an incentive to stay on the walking track, because that's where the answer is, not GZ]
2. Nearby (S33 47.225 E151 08.801) is a set of stone steps that take you from the nearby road to the path that passes GZ. How many steps are there at this location?
Please do not put the answer to these questions in the log, otherwise I will encrypt the log. Also, since most people will get the answer right, if you don't receive a reply from me within 24 hours, you can assume that you are right and log the visit. Note that I operate on the honour system. I do read and validate the answers provided, but do not reply unless there is a direct request or question. So if you would like me to do something specific, please speak up.
