Geography and Geology

Quamby Bluff lies from Deloraine by road, just north of the main escarpment of the Great Western Tiers mountain range. The name Quamby has been variously stated to be derived from

, the district in Huddersfield Yorkshire, or from a Viking word that means "mill farm", though most likely from local Tasmanian languages meaning either a "place of rest" or a "good camping place". Daniel Bunce in his 1859 book of memoirs postulated that the name was derived from an incident where a British colonist in the area aimed his gun at an Indigenous Tasmanian. The Tasmanian feel to his knees and yelled "Quamby!" which was interpreted to mean "Spare me!" or "Mercy!". The Tasmanian central plateau was uplifted from the lower Meander Valley, most probably in the

epoch though possibly earlier, forming the escarpment of the Great Western Tiers. The face of the tiers has been eroded and retreated approximately since then, leaving Quamby Bluff as a solitary outlier. The bluff has similar geology to the rest of the range, and a similar form with cliffs, and talus (a mixture of

The area around the mountain has an annual average rainfall of with a predominance in winter.Lloyd, p.11 The rainfall increases significantly with altitude, approximately measured at rising to at the summit. Snow is seen above at any time of year, and there is regular snowfall on top of the bluff. Due to its exposed position the summit often experiences severe weather conditions.


Habitation and landuse

The original inhabitants of the area were the Pallittorre Clan of the Northern Nation of

s. The North Midlands Nation name for Quamby Bluff was lartitickitheker (lar.tit.ick.it.he.ker). There are caves south of Meander, in the Great Western Tiers, with deposits showing aboriginal habitation, though these have not been dated. The deposits were either left by the Pallittorre, or their neighbours the Luggermairrernerpairre who were part of the neighbouring Big River tribe. The Pallittorre probably inhabited the area for thousands of years; aborigines are believed to have lived in Tasmania for more than 30,000 years.Breen p.1 They maintained cleared grassy plains by regular careful burning, and used this method also to control undergrowth in the forests. This land management technique enabled easier hunting and food gathering.Breen, p.3 Over an 18 Day period in July, 1827, 100 Indigenous Pallittorre people were massacred by Corporals William Shiner and James Lingren from 40th Regt; stockmen Thomas Baker, James Cubit, Henry Smith and William White in response to the killing of three stockmen. There has not been a survey of the mountain for aboriginal artefacts. Stumps and trails remain as evidence of logging by European settlers; the remains of a 1940s sawmill can be seen on the Eastern slopes.Lloyd, p.16


Flora and fauna

The bluff's nature as a solitary outlier of the range gives it a greater range, in one place, of habitats and flora than elsewhere in the Great Western Tiers. The plants and trees found on the bluff are common to the rest of the range however, unlike the rest of the range, Quamby Bluff's summit does not show evidence of burning or grazing damage. The mountain has a mixture of habitats including

. The last recorded fires in the forest reserve were 1961, when some of the drier forests burned, and 1968, when the northwest corner was lightly burned. Parts of the reserve had been selectively logged for around 100 years until 1982, mostly for sawlogs.


Reserve

The mountain lies within a forest reserve, listed on the Australian
Register of the National Estate The Register of the National Estate was a heritage register that listed natural and cultural heritage places in Australia that was closed in 2007. Phasing out began in 2003, when the Australian National Heritage List and the Commonwealth Herita ...
, declared on 15 December 1982. This reserve largely covers the area above an elevation of and covers of a landscape described as predominantly in its natural state. As of 1990 both Quamby bluff and the forest reserve are closed to mining exploration and prospecting. The reserve was added to the Tasmanian Wilderness World Heritage Area in 2013. Quamby Bluff is one of the Tiers' easier peaks to ascend on foot. The walk to the summit is a popular day walk and can be easily completed in an afternoon. The most popular trail, of the four that are marked, is the ''fairly glade'' track that is accessed from
Lake Highway The Lake Highway, or A5, is a main highway and A-road in Tasmania. Although still known as the Lake Highway the official title of the road was changed in 2001 to Highland Lakes Road. The Lake Highway branches off the Midland Highway at Melton ...
. There are no formal car parks or facilities in the forest reserve. The walks are marked simply, with some small coloured metal triangles, cairns and track markers of coloured plastic tape. Camping is permitted and dogs are allowed on leashes. Hunting is not permitted.Forestry Commission of Tasmania, p.20
