I've only heard about this mega Tsunami about 6 months ago and years ago i worked doing major earthworks in the Ellenbrook area and the ground there is just like soft beach sand and about a meter or so down we would find shells and ocean fossils which would explain a lot of things that I saw. Great work on your video and i will be following as I'm a bit of a WA history fanatic
Hello Galoop. Thanks for the support. I have been doing a lot of exploring on foot around the Perth Metro area in the last few months and I am finding more evidence as I go. I see the same soft sand everywhere. I have collected sea shells in the sand in a couple of places. I have a few videos in the Metro region in production. Stay tuned.
Great video, given that the less salt tolerant, greater nutrition requiring leafy vegetation exists at a lower altitude than the heath vegetation, albeit only a few metres elevation change. Would you suggest the elevation change was created by salt and debris deposition at the edge of the wave as it lost momentum? Look forward to seeing the results of salt concentration in soil samples either side of this divide- perhaps even a core sample to evaluate change over time
Yes I think the wave deposited the coarse sand layer at this point, I'm calling it the Sand Wave Snout, where the salt water wave ran out of momentum as the wave travelled over the land. The 5 meter sand layer appears to have been deposited over the mature soil. The land in the region is undulating with a relief between zero meters, sea level, and 225 meters above sea level. The are locations where the mature forest is at higher and lower elevations than the sand wave snout, but wherever the sand wave snout is found, it is always several meters above the mature soil. I have a few soil and sand samples from either side of the sand wave snout that I will be looking at in the next episode. It would be great to get a core sample at the same location and see if there is a vegetation layer at 5 meters below the sand layer, especially if it could then be carbon dated. Stay Tuned.
Hey Geoparks, yes I can confirm a lot of evidence in the Perth Metro area, such as Bold Park which has both chevrons and is coastal heath vegetation. Nearby is Mount Claremont, and the mount itself is actually a chevron. I have not been able to follow the sand wave snout so far in the metro region due to the human development. That's info for two up and coming episodes in a couple of months time though. South of Perth, in the Bunbury region I have seen on the map but not yet visited to confirm on the ground a sand wave snout at 14km from current coastline, that's the furthest so far and another episode. North at Two Rocks the sand wave snout is a few kilometres inland as well. I have been and looked but I am still gathering data in this region before I can confirm my findings. Episode later in the year.
Thank you. There is actually zero evidence for the Burkle Crater, apart from the chevron dunes around the Indian Ocean. Also there are multiple different dune layers, as this is a recurring event. I recommend you watch my episode 5, where I triangulate and show where the tsunamis originate.
Gotta say, as a layman, this video is not super compelling to me. These formations either look like nothing, or like they could have many other explanations. Though the transition zone is a bit more convincing than the rest. Came here from a short about dunes that seemed stronger, and i figured I'd start from the beginning. Might be good to redo and intro video that works through the evidence in order of how compelling it is.
Fair enough. However, I'd advise also watch episode 2, as there is a bit more to these sand layers, and where I walk along and through the transition zone at another location a few km's to the north, and take some samples too. The problem with this subject is, it takes a whole range of different bits of evidence to make the whole. Also, this video used to have a full intro, but as I researched and discovered more evidence it was clear the intro was just incorrect. UA-cam allows editing unwanted sections out, but we are not allowed to add to or over write on existing videos, and I don't want to lose the viewing hours already built up by fully deleting this just to upload the same thing.
@@blakemcalevey-scurr1454 I have the next video written and filmed, and have started editing. The next is in the can... but not yet written. Takes a while with my other life commitments.
The dunes I have been studying in the Margaret River Cape to Cape region are located on cliffs and higher ground, places where wind blown dunes cannot form. This is very well documented worldwide. At the Sculpture Park we found shell fragments 3.4km from the coast. Wind does not blow shell fragments any distance. I have proven this myself experimentally.
Yeah true that , I live 180km from the coast 500km north of Margaret River and often found shells about 30cm down when digging . Figured it was a big wave that bought them 180km inland 👍.
@@shaneoreo4362 What's the location? Are the shells bivalves or conical? Some of the conical shells are actually land snails a fact that caught me out on one of my videos.
@WATsunami , Yeah the place is a small town called Perenjori, most definitely sea shells , I even found a cowrie shell one day , all as I mentioned about 30cm under ground ground
What evidence do you have that the sand layers are not just regular wind blown sand dunes. One would expect tall trees in lower lying areas with better soil.
Much. 1, aeolian sand dunes do not form on the top of cliffs. 2, aeolian sand dunes are formed from the finest particles only, and yet we have collected sea shell fragments at the sculpture park, the only place we have permission to dig so far, see ep2. 3, there is no trail off of the sand layer, as would be expected for wind blown sand, see ep2. 4, the sand layer does not reach the very summit of Leeuwin and Boranup ridges, the karri trees grow at a slightly higher elevation, a place where we would not expect the richest soils. 5, the sand dune orientation bears no relationship to the prevailing winds. 6... ep7 comes partly from UK where I do visit wind blown dunes. There is a lot more evidence to come in future episodes.
@@WATsunamithanks for your reply. Afraid I'm not convinced. shells could have been deposited when the sea level was higher (millions of years ago), and later eroded. Wind can move large sand particles particularly in that part of WA where there are super strong winds.
@@sheriefkhorshid1951 Wind never moves larger particles. Have a look at my 4k time lapse wind blown sand video, and please view some other videos regarding sand dunes from other parts of the world. Also please have a look at my short video about cross banding. The sand layer is very recent geologically, a few thousand years old. At some point we will be doing some core samples at the sculpture park where there is a vegetation layer a few meters down. We will be carbon dating this. Also, please see my Tamala Limestone to see a water lain shell layer, it is very different from isolated shell fragments. I have many more videos in the planning and production stage to address these points.
Using ASL just makes it easier to understand. Also, along the coast of this region of Western Australia, the tidal range is almost negligible, so it's not going to be that different. I have not verified this however, that's just my thoughts. I will be speaking more about tides and how this relates to sand dune formation in a future episode.
Does anybody know how this affected the middle east. The wave must have reached the red sea. The rain around the world must have starved people, maybe to death.
There are also deposits in Madagascar and South Africa, which could come from this series of events, but there are also identical features around the Gulf of Mexico in the USA and Mexico, and also on Pacific Islands. These are caused by undersea continental slope landslides, and can happen on any ocean coast.
So I am presuming you have dug holes here both on the sand layer and also inland from the sand layer and have had the sediments examined and reviewed by geographers and geologists who also made the same 'horseshit. comment? Could you please include a link to your reference?
@@WATsunami Yes I have dug holes in this area, thousands of them. You so called tsunami wave transition zone is just a sand dune blowout that has re-vegetated. Have a look on google maps just North of Hamelin Bay, and West of Karridale, you'll see blowouts still moving. Have a look at Yeagerup Dunes. A dune blowout that's still moving. They are all over the Southwest coastline. They continue their windblown movement until there is a wet enough year for vegetation to re-establish and stop the sand blowing. There are petrified vertical Karri trunks in Neils Pit at the original ground level, that are 25m below the current ground level. I get it that you are interested in geology, but you can't start with a conclusion and look for evidence to support it, that's not how science works. Do some actual research from verified sources, do a university degree or something, but stop posting videos with your dubious ideas as though they are facts.

ooops wrong profile. oh well you can see it's me.
Great drone footage and is informative. Lots of time and effort was put into this, so well done.
Thanks Chris.
really interesting looking forward to the next episode.
Stay Tuned!
Great video mate. Looking forward to watching the rest.

This wave is also evident on the shore of Madagascar.
Hi, If the tsunami impacted this high up the Cape to Cape, the it must have devastated the Swan Coastal Plain. Can you comment on this please?

Was this due to the Burckle impact? Great content. 👌🏾

This is just wind erosion over thousands of years and vegetation adapting and moving with it.

soon as you put up the acknowledgement bullshit i switched off
I know we’re all a bit sick of it, but you just got to accept it😂
No need for the aboriginal acknowledgement at start of the video,as a Aussie I can tell you we are sick to death of this Woke crap.
Lol😂
This is crap. I dig holes here professionally, the "facts" in this video are horseshit.
