This cache was part of the 'Australia Wide Geocache Series: Explorers'. There is a clue in the cache which contains information about the location of this State's Prize Cache, which was meant to be found when you collected enough clues. There were not enough other caches published in the series and the project appears to have floundered. There isn't really any point in taking note of the clue now.
Gregory Blaxland arrived in New South Wales in 1805. He acquired land in the colony and became a successful farmer. He wanted to expand his landholdings, but was not able to secure any further land grants from Governor Macquarie.
Concluding that best solution to his problem would be discovering a route through to the interior of the country, Blaxland petitioned Macquarie for permission to seek a way across the Blue Mountains.
In May 1813, he, William Charles Wentworth and William Lawson set off from Blaxland's South Creek farm (near present day St Marys). There is a plaque marking this location - see multicache GC4VT12.
Blaxland, Wentworth & Lawson are now famous as being the first explorers to cross the Blue Mountains. This isn't strictly accurate, rather they were the first socially acceptable, British group to cross.
John Wilson (between 1792 and 1797) and Francis Barrallier (1802) had earlier found routes across the Mountains, as did a small herd of cows (seriously!). And George Caley led a group to Mt Banks in 1804. It was Caley's experiences in exploring the area near the present day Bells Line of Road that suggested to Blaxland that following ridges rather than valleys would give them the best chance of successfully crossing the Mountains.
21 days after they set out, the group made it to Mt Blaxland, on the western side of the Blue Mountains. Six months later, George Evans followed their route and made it across the Great Dividing Range and into the fertile plains beyond.
Unfortunately for Blaxland, Macquarie did not grant him any additional landholdings in the interior, and he sold most of his livestock in 1814. He continued to farm at his Brush Farm property (near Eastwood), experimenting with a number of crops. He was particularly successful at viticulture, winning several awards in London for his wines. He mostly withdrew from public life, with his suicide in 1853 barely noted in the press.
The starting location for this cache is Blaxland's grave, in All Saints Cemetery, Parramatta.
From the headstone, make a note of Blaxland's date of death, you will need this at the next waypoint. Then, standing at the foot of the grave looking at the headstone, look for the grave immediately behind the headstone. The grave you are looking for is for a person with the initials MA(M)S. Her date of death is AB CD EFGH (in DD MM YYYY format). And she was JK years old when she died.
Now head over to the memorial in the corner of the cemetery (S 33 48.359 E 151 00.622). Here you will find a number of plaques, listing everyone who is known to be buried in the cemetery.
Find the plaque which includes Blaxland - the plaques are in date of death order.
Find the person listed at the bottom of this plaque (initials are CW). CW's date of death is LM/N/PQRT, and her age at death was UV
The cache is located at:
S 33 TH.KJQ
E 151 GC.(V-K)(U)(D-L-U-R)
There are seats near the memorial which will provide a convenient spot to calculate the location of the cache. The cache is a small sistema.
