Statement of Significance
Sierra Nevada is historically significant and representative of a small group of large iron-hulled international cargo sailing vessels wrecked on Victoria's west coast. Sierra Nevada has some social significance as the events surrounding the wreck and its aftermath represented extreme ends of the local community's social values. As part of the group of iron-hulled trading vessels wrecked on the west coast, Sierra Nevada's cargo helps makes up part of the picture of the particular tastes of Victorian society and economy in the late 19th century. At the last site inspection in 1985, Sierra Nevada was broken up and scattered over a large area. There is potential for archaeological significance through typology studies of cargo materials providing reference information for other areas of historical archaeological research. Scientifically, Sierra Nevada can contribute to corrosion studies as an iron hulled vessel carrying iron cargo.
Significance assessed against criteria defined in Guidelines for the Management of Australia's Shipwrecks (1994)
CRITERION 1: HISTORIC
Iron as a shipbuilding material was in use for a relatively short space of time, being replaced by steel at the beginning of the 20th century. Sierra Nevada is historically significant and representative as one of a group of large iron-hulled international cargo sailing vessels wrecked on Victoria's west coast.
CRITERION 2: TECHNICAL
Iron ship builders are known to have deviated off ship plans so Sierra Nevada may have some technical significance if there is enough remaining of the vessel to study the ship's construction.
CRITERION 3: SOCIAL
Sierra Nevada's wrecking event was representative of social values of the time and created extremes in social behavior in the communities near the wreck site. Stories of lives lost were overlaid with some people's desire for washed up alcohol from the wreck creating drunken brawls over unattended corpses. As part of the group of iron-hulled trading vessels carrying cargo to Melbourne and wrecked on the west coast, Sierra Nevada's cargo makes up part of the picture of the particular tastes of Victorian society and economy in the late 19th century.
CRITERION 4: ARCHAEOLOGICAL
The wreck lies on an unprotected reef and is subject to aggressive sea action. At the last site inspection in 1985, Sierra Nevada was observed to be broken up and scattered over a large area. Ironwork and cargo items are cemented onto the substrate. Some areas of broken concretion were noted where divers have used chisels or crow bars to expose ceramics and bottles. A workshop lathe bed is visible and a large amount of flat iron bar which may have been ballast or cargo. Sierra Nevada's cargo could potentially contribute to typology studies of cargo materials. These studies have the potential to provide a reference collection for archaeological research into areas relevant to trade and consumerism.
CRITERION 5: SCIENTIFIC
In 1985, the scientific value of Sierra Nevada was seen predominantly in its cargo. Sierra Nevada could contribute to an area of research relating to the importation of materials into Australia, what market forces were at play and whether the material was available locally or not. As an iron-hulled ship carrying an iron cargo, Sierra Nevada can contribute information to any future corrosion studies.
CRITERION 6: INTERPRETIVE
It is possible to dive the site in good weather but due to the scattered remains any interpretive significance lies off site.
CRITERION 7: RARE
Sierra Nevada is one of five iron-hulled trading vessels wrecked in and around Port Phillip between 1883 and 1900. This group of vessels presents a rare picture of international iron sailing vessels trading with Melbourne.
CRITERION 8: REPRESENTATIVE
Sierra Nevada is representative of the large iron trading vessels that were used for a short time towards the end of the 19th century before steel took over. Iron's short life span in shipbuilding was due to complications associated with iron hulls such as compass anomalies and the corrosive properties of iron and water.
