Forest Caves is one of natures naturally occuring wonders. 2.3 Million years ago ash exploded from the nearby volcanic vents. The ash settled to form a soft layer of red rock. Sea caves are formed by the power of the ocean attacking zones of weakness The weak zone is usually a fault, or fractured zone formed in sedimentary rocks where a layer of softer rock is interbedded between harder layers.The cave may begin as a very narrow crack into which waves can penetrate and exert tremendous force, cracking the rock from within by both the weight of the water and by compression of air. Sand and rock carried by waves produce additional erosive power on the cave's walls. Typically these occur in caves formed in sandstone or basalt.
Over time this rock platform was eroded by wave action into the series of large caverns. Although some of the caves have partly collapsed the formation is still over 3 meters high. The splendor of Forest Caves is best viewed at low tide.
To log your visit, you will need to do 3 things.
1.What is the name of the soft layers of red rock formed by the fallen ash? This information is on a sign between the carpark and the caves.
2.Enter the larger of the two caves (the one with the hole in the roof) and email us a photo from inside the cave of you with your gps
3.Sign natures logbook, by writing your geo user name in the sand and send a photo of it with your log.( TIP: Use a key or coin to write name in sand as it comes out better on a photo.)
