Quaternary alluvium covers the main western part of Pialligo. Calcareous shales from the Canberra Formation are deep underneath. The Woolshed Creek runs into the north end of Pialligo. This is a significant place, because in the bed of the creek the Rev W B Clarke first recognised Silurian fossils. These fossils were brachiopods, mostly Atrypa duntroonensis. He discovered them around 1844 century and it was the first time that Silurian rocks were identified in Australia, and at the time were the oldest known rocks in Australia. This mudstone is from the Canberra Formation.^[3]

Aside from the city's design, arguably Walter Burley Griffin's longest-living legacy in Canberra is the forest of Redwood trees (both Sequoia sempervirens and Sequoiadendron giganteum) that was planted in 1918 by Walter Burley Griffin and arborist Thomas Charles Weston on Pialligo Avenue.
