In the bush, near the industrial estate of Lawson, NSW is a rock ledge that has a cage on top. The cage goes over a large hole that has an unknown history. There still seems to be no conclusive answers, what are your thought’s on what this hole was used for?
- It’s nowhere near the current highway
- The Lawson Industrial area was used for farming
- It’s about 7 metres deep and about 1.5m wide
- There is an access hole at the bottom
- It’s been dug through rock about 1.5m from the edge of a cliff.
Blue Mountains Historian, John Merriman, concludes that it was used as a Grain Silo for the Glen Orchard dairy. https://goo.gl/y1Wxec
Blue Mountains Local Studies support the idea of s Silo: “The capacity of the shaft may be calculated to be about 16 tonnes of grain or ensilage. Ensilage is made from pasture plants cut when green, which is compacted, sealed and allowed to ferment without air, forming a material similar to sauerkraut; cattle relish it once they get used to the taste (Woods 1883, Sutherland 1980). Grain may also have been delivered by cart or truck down Somers Street from the highway or railway to the top of the silo from where it could then be removed at the base as required for stock feeding. A full silo of grain would by my calculations feed a dozen cows for six months and so ensure security and continuity of milk production.” Refer: Click here for more info
