History

On the North Eastern side of Theodore are the Theodore Grinding Grooves. The Theodore Aboriginal artefact grinding grooves demonstrate an important aspect of past Aboriginal lifestyles and technology. A place of this type is rare in the ACT and highly valued by the Ngunnawal people as evidence of the importance of the artefact grinding process and the surrounding area to their ancestors. It is a notable example of this type of site, with a large number of grooves and associated artefacts, indicating continuous and varied use of the site over time.
