This walk begins at Hyams Beach and crosses the wave cut Snapper Point Formation with some excellent rock pools. We can observe the human intrusion on this section of the walk. The first house, on Hyams Beach, is vulnerable to storm and rain erosion from its proximity to a creek outlet and the Bay. Observe the boundary between introduced and original vegetation.
This human activity continues until we pass the ‘First Creek’ on Seamans Beach. Considering the popularity of Hyams Beach the impact has been fairly gentle, if ugly.
Proceeding along the beach, we can, over time observe the impact of wave erosion and sand migration. 1999 was particularly violent and the fore-dune lost approximately a metre of sand. Wattles, spinifex, pigface were suddenly exposed to salt water and suffered.
Look for the ‘blowouts’ in the old dune. Are these legacies of old human and animal paths or are they some other influence? On reaching the Navigation Marker, climb the dune and you can observe the structure of this system. Quite stable in 1999 but clearly dynamic, until reaching the older dune stabilised by the B. serrata and Tea Trees.
Geology: Beaches (recent), with dune fields behind. There are places where outcrops of sandstone can be seen on the beach.
Vegetation: Open Forest (Community 2) on the first section of the Seamans Beach old dune and sandstone (more seen than experienced) and Woodland (Community 7) further south (again on the old dune). Banksia serrata is predominant. On the beach, and behind the fore dune, Spinifex hirsutis, Acacia longifolia, Carpobrotus glaucescens and Actinotus helanthi are abundant.
