Along a small creek near the Topham Trail are a few Axe Grinding Grooves (AGGs).
Between some of the potholes in the creek bed are channels, which direct water seepage into and around the potholes. Research by Jo McDonald found that: “water channels occur on a small proportion of engraving sites (c.3%). All sites with water channels also have grinding grooves present. Of the sites which contain engravings and grinding grooves, 23% also have water channels”.
