Gold Trap Sluice

gold trap sluice

    sluice

  • (in gold mining) A channel or trough constructed with grooves into which a current of water is directed in order to separate gold from the sand or gravel containing it
  • An artificial water channel for carrying off overflow or surplus water
  • conduit that carries a rapid flow of water controlled by a sluicegate
  • irrigate with water from a sluice; “sluice the earth”
  • pour as if from a sluice; “An aggressive tide sluiced across the barrier reef”
  • A sliding gate or other device for controlling the flow of water, esp. one in a lock gate

    gold

  • A yellow precious metal, the chemical element of atomic number 79, valued esp. for use in jewelry and decoration, and to guarantee the value of currencies
  • A deep lustrous yellow or yellow-brown color
  • coins made of gold
  • made from or covered with gold; “gold coins”; “the gold dome of the Capitol”; “the golden calf”; “gilded icons”
  • An alloy of this
  • amber: a deep yellow color; “an amber light illuminated the room”; “he admired the gold of her hair”

    trap

  • Basalt or a similar dark, fine-grained igneous rock
  • a device in which something (usually an animal) can be caught and penned
  • place in a confining or embarrassing position; “He was trapped in a difficult situation”
  • catch in or as if in a trap; “The men trap foxes”

Gulaga Mountain and a Patch of Rainforest

Gulaga Mountain and a Patch of Rainforest
Gulaga Mountain, previously known as Mount Dromedary was one of the strongholds of rainforest in south eastern Australia. Situated south of Narooma in coastal New South Wales, the mountain contained a significant area of lowland and mountain rainforest.

An extinct volcano, formed in the Creteacous period, some 95 million years ago. The two main rock types are granites; the more fertile monzonite on the outside, and the less fertile syenite on the inner side. At this time, New Zealand was attached to this part of the world, before it decided to head off east. Captain Cook named it Mount Dromedary, as it apparently resembled a hump of a camel (dromedary). The highest point of the mountain is 806 metres above sea level.

The soils on the mountain today are relatively fertile. Combine this with fire free areas and a good level of rainfall, the rainforest flourished. Someone said that the oceanic current down the east coast of Australia brings warm waters and moisture, and it curls around and hits the coast near Narooma. And this is why the rainfall (and fishing) is good here.

Ages ago, when the volcanic magma cooled, cracks formed in the new rocks. Vapours became trapped in the cracks and deposited gold, quartz and other minerals. All streams from Gulaga mountain are auriferous (gold bearing). Gold is a passion for white man, and soon the mountain was full of prospectors.

In 1902 there was a permanent population of 400 on the mountain. With a little town and school. Now, of course there are none, and only a few brick walls and old mining relics still show. 19th century mining practices are not great for the environment, and much damage and fire occurred, destroying large areas, particularly the mid and low altitude rainforests.

Originally Mount Dromedary was nominated for World Heritage status, but subsequently removed. I phoned the government officials in charge in Canberra. Asking them why, they said "dunno". And if they could find out why, they said "no".

The lower altitude rainforests that exist are mostly in a degraded form, after mining and repeated fires. Interesting sub tropical species still grow here. Such as Small-leaf fig, Giant Pepper Vine, Giant Stinger, Elkhorn Fern, Koda (Ehretia acuminata) and Brush Bloodwood (Baloghia inophylla). According to A.G. Floyd, this is the southern most limit of twelve rainforest species. A couple of warm temperate notables are Jackwood and Native Crabapple. (Cryptocarya glaucescens & Schizomeria ovata). The low altitude rainforest has 24 tree species, eight of which are sub-tropical types.

Attached is a photo showing rainforest patches in the mid to low altitudes, the pale green bit is rainforest. Mostly populated by Doryphora sassafras & Syzygium smithii. (Sassafras & Lilli Pilli).

Luckily, the highland rainforest is in good condition. Cool temperate rainforest is dominated by Pinkwood (Eucryphia moorei), with a number of associate species. The largest Pinkwood are around 30 metres tall. (I paced out a fallen tree at 36 paces). So, it’s a tall rainforest of a delicate beauty. The distant Pinkwood foliage is a feathery light green. Another appealing feature is the diversity of ferns, and the hanging moss. It’s a truly gorgeous place.

This poem was published at least twice, and has proven popular with some readers:

Mount Dromedary

I parked the car by the General Store
And the rusting tins of kerosene,
It’s rained for a week and then some more
And everything about is green.

With a steaming horse, the hopeful trod
This track around a mountain stream,
From a gushing sluice they sought their god,
The yellow weight, their muddied dream.

There’s a broken hearth where miners slept,
They spun this giant engine wheel
Before the flaking brown had crept
Around the boiler’s buckled steel.

Footsteps, then a glimpse of chain
And huge grey boulders round and cold,
By blue protruding porcelain
There’s talk again of days of gold.

Under Pinkwood trees is "old man’s beard"
A hanging tangled mossy shroud
In ghostly white and vision weird
Through drowning mist of mountain cloud.

The final climb the steepest part
With ten more minutes ’til it’s done,
Unwrapping lunch with a banging heart
By gold-necked lizards in the sun.

Beneath this ridge is a covered mine.
And towering limbs from fiery ground,
My steps now taken in decline
Past any treasures yet un-found.

This Mark digging out a sluice channel. The sluice is next to a weir, both of which are being worked on. The weir is going to be set up to measure the water flow down the river as part of an ongoing information gathering exercise to look at the effects of mine workings on the river (which disappears during the height of summer – probably due to water escaping into the old sough and other workings).

The weir is there as their used to be a man made channel running alongside the Lathkill (the far side in this photo). It started here, from the pool behind this weir. It ran down the dale and over an aqueduct to Mandale Mine to power a huge water wheel (that in turn pumped water out of the mine).
