Step Into the Geological Story of the Hemel-en-Aarde Valley
Join the Overberg Geoscientists Group for a guided excursion led by John Blaine, alongside Dylan Blake and John Bristow.
This full-day experience takes you through the Onrus River system, uncovering the powerful forces that shaped the valley over thousands of years.
Expect to explore:
• Ancient land surfaces and river terraces
• Evidence from the September 2023 floods
• Waterfalls, peat beds, and river evolution
• Fascinating signs of early human activity
With multiple scenic stops, short walks, and hands-on exploration, this is a rare opportunity to see geology come to life in one of the Overberg’s most iconic landscapes.
