The above coords will give you a place to park when visiting Kalamina Gorge.
This is a "choose your own adventure" Earthcache. You choose your own difficulty level :)
The Hamersley region is one of the Earth’s oldest, containing rocks that have been in existence for at least 3500 million years. Various geological processes have shaped the region - mountain building, formation of an ocean basin, violent volcanic activity, impact from meteorites, slow weathering and many forms of erosion. Evidence of all of these geological processes are seen in the rocks here.
The rocks in Karijini National Park reveal that a collision of continents occurred between 2400 and 1600 million years ago. The Pilbara continent collided with the Yilgarn continent to the south. The massive impact caused the rocks to crumple and fold. Enormous forces then thrust the rocks upward to form a mountain range at least 500km long.
A hint of the power of thrusting and folding processes can be seen in the folded rocks throughout Kalamina Gorge.
A relaxed ramble through the gorge will reward you with many different rock formations, shapes and distinctive geological landscapes. When we walked through here we were amazed by the marked geological changes in very short distances.
The following is our photo gallery taken in Kalamina Gorge.
Below are all of the coords for the above photos. The coords are listed roughly closest to the info bay to furthest along the gorge. It is up to you to choose how far you wish to walk along this gorge to complete the Earthcache. You may choose to check them all out but please only log your 3 favourite ones.

To log this Earthcache there are two distinct tasks. You may log straight away but then please email your chosen answers to the questions to the CO. We will contact you ONLY if your answers need extra work. Logs with no answers sent will be deleted.
1A. LONGER walk: Describe the geological formation at S22 24.873 E118 24.432
1B. SHORTER walk: Describe the geological formation at S22 25.041 E118 24.137
2A. Match any 3 of the photos with the coords and explain the geological process you think has caused the phenomenon in each one. For example A = coords and process.
....OR....
2B. If you don't have the photos handy, please choose any three of the coords, describe what you see and explain the geological process you think has caused the phenomenon in each one. For example: coords = description and process.
We have attempted to make a fun Earthcache with a difference but still enable you to ponder the geological processes of the area with your own hiking ability in mind. Choose your own difficulty level and have fun:)
