Thank you. Would it be possible to see some of the limestone with shells as you mention? Sounds like an interesting location I should see in person.

I have not yet been to Albany. It is definitely on the to do list, likely in 2026. I have already have multiple locations I would like to study when I visit the region.

@WATsunami Yeah you will be amazed at some of the spots. I grew up here and know alot of Interesting places as ive been to most fishing spots. I would be happy to be a guide when you's do get here. You will need to spend a bit of time tho because there's alot of places to visit that I reckon you would be interested in

@ I will let you know when I am on my way!

@WATsunami No worries. I'll keep tuned into your vids. Great work.👍 This is an ancient land.

@ Thank you

The Burkle Crater theory has been all but debunked. To create a 20km wide crater in the deep ocean at a depth of 5km takes a 6km wide asteroid coming in at steep angle. There is zero evidence this happened 5000 years ago in the Indian Ocean. I will be doing a full video on this subject in the coming months. Please view our episode 5 where we triangulate the WA chevrons to the Naturaliste Plateau off the south west coast.

@@WATsunamithanks for the reply, glad that you are being thorough with the evidence. Happy to be corrected and to learn more.

@ In the next few weeks I am hoping to do a video interview with a professor of astrophysics who quite literally wrote the book on asteroid impacts. I attended one of his lectures on this very subject in 2023.

I have not yet looked at these features on the ground, but, the whole area is a series of ridges made up of the Tamala Limestone. On top of this, mainly towards the current coastline, are some tsunami deposited sand layers. These layers were then blown by the wind across the entire region. Any human activity obscures and destroys any natural features. There are definitely some nearby features, as seen on Google Maps, that look like splash zones, meaning areas where waves flooded in and deposited some sand over a wide low area, as opposed to the surging flow on the coastal edge which generates chevrons. This type of splash event was experienced by the Sendai area in Japan during the 2011 tsunami. Lots of video of this on UA-cam.

@WATsunami Thanks. It is quite a fascinating subject and makes a change that it's about Western Australia,which is usually a forgotten or ignored part of the country.

@ Do you have a Google Maps location grid ref so I can have a closer look at the exact area you mean?

thank you

That region is on our very long term to do list. If you watch our episode 5 we mention Hartog Island just to the south of the location you mention. Also, the original source of information for this channel is The Holocene paleo-tsunami history of West Australia www.researchgate.net/publication/37359410_The_Holocene_paleo-tsunami_history_of_West_Australia which discusses the region you mention. Have a look at Figure 1.

Please cite your references.

Thank you. This is just something of a snippet of Moore River where it is accessible. The Moore River Nature Reserve and National Park are quite untouched as are places like Orange Springs where I got lots of shots of nothing but trees.

We have a trip planned in February which covers the region you mention. We will be staying at Cervantes but have a visit to just south of Dongara planned too. This will feature in several upcoming episodes.

Yes there is a story. Check out our short videos where we cover this. We will be looking at this in more detail in a future episode.

They look like they are tsunami deposits, from Google Maps. But you have to see them on the ground to be sure. We have a trip to Cervantes, Leeman and Arrowsmith coming up next month. Videos to follow.

I agree it is an important natural wetland. One of the aims of this series is to highlight our environment and get more protections in place across the areas we highlight, especially the coastal dunes north and south of Bunbury. These dunes cannot be regenerated they can only be preserved.

@@WATsunami I"ll need to watch the Bunbury parts in more detail.

@@BDub2024 Episode 5 shows the dunes to the south of Bunbury too.

You are welcome. I was literally curious about these lakes for 20 plus years.

Keep reading your 1 book and leave the science to people who know what there talking about

@matc87 keep that which is committed to thy trust, avoiding profane and vain babblings, and oppositions of science falsely so called: 1 Tim 6:20.

I am not too concerned during our lifetime as these events appear related to sea level changes due to ice ages and interglacials. Saying that I would only live at least 20 meters above current sea levels in this region.

I also lived in Rockingham for some years many moons ago. The flat sandy limestone geography, the vulnerability to a southbound Tsunami originating from the Indonesian alchepelago did not escape me either. It even looks like it has seen major inundation from the north in the relatively recent past across the low country where CBH and the industrial estate is now located, moving inland across Dixon rd, and Hillman up to the escarpment and on to inundate lakes Cooloongup and Walyungup and the flat country beyond.

@ This the map I used for this episode. It clearly shows every ridge and is an excellent way to measure the spot heights too: en-gb.topographic-map.com/map-nj18/Australia/?center=-32.62145%2C115.70389&zoom=11&base=3

I always put a typo in every episode. oops. You are correct I actually meant Ledge Point, and not 'The Point' near Wedge Island. I simply missed this on my proof reading.

I just added a note to the end of the video text description: Typo correction: at 5.45 to 6.10 it should say Ledge Point, not Wedge Point as in the video.

There are likely to be so many parts of the West Australian coastline that have been modified and sculptured by tsunamis. The Indian Ocean formed over 100 million years ago when dinosaurs still roamed the planet. Do you have a map reference I could look up for this location?

@ 20deg 37’ 50” S 116deg 47’ 48” E on Google Earth you can see what appears to be a sand filled area between the mainland and Burrup Peninsula, it is more easily appreciated at ground level, there is an elevated road that now provides access to the oil and gas developments where I used to work.

@ apologies I thought I replied earlier 🤦🏼‍♂️ google earth Lat and Long 20degrees 37’ 48” S 116degrees 47’ 48” E Hearson Cove you can see the sandy beach and the prominent rock formations with a salt flat in between it is very noticeable when you are ground level…

@@steverichardson6920 I am viewing on Google Maps. Yes it's a very interesting location. Looks like an inundation event from the east moving west. But.... could also be other things too. I don't know anything about the rivers, tides, winds ETC at that location to make a comment. Study required. I will add this location to my (very) long term to do list.

With global warming we should expect to see even more glacial generated tsunamis in high latitudes. I have a video on this subject which also discusses the Storegga Landslides which are very much related. I recommend this video I watched during my research: Unlocking Scotland’s Tsunami History ua-cam.com/video/xgEIb8KNVzc/v-deo.html

Could you provide some references please? The boulders at Leschenault are in fresh dunes above the highest estimates of sea levels along this coast for the last 10,000 years. There is something called the Mid-Holocene Highstand which contradicts sea level change maps from the UK for example, and is something that could well be attributed to other events in the Indian Ocean, such as tsunamis. For ballance and transparency, here is the source I used when researching this video: Glacial Isostatic Adjustment modelling of the mid-Holocene sea-level highstand of Singapore and Southeast Asia www.sciencedirect.com/science/article/pii/S0277379123003803

Chevron shaped deposits from that impact evident in South Africa, Moza, Madagascar and Mauritius also

Is there any detailed topography available of the purported Burckle crater. Given that an impact is said to have occurred just 5,000 years ago, there should be reasonably clear evidence.

​@lupus7194 There is indeed. Lots of it. Search and you will find.

@ There is actually no supporting evidence that a 6km wide asteroid hit the Indian Ocean 5000 years ago leaving a 20 km wide crater 5km deep on the ocean floor. If you watch our episode 5 we triangulate the west Australian evidence and it points at the Naturaliste Plateau off the coast of the South West of WA.

I find quartz grain sand layers, which is like finding fresh beach sand, all over the Swan Plain, many kilometers inland. Quartz grains can be many millions of years old. Do you have the grid reference for the oyster shells you found? Were they in sand or contained in limestone? We always have to look at the tectonic activity of the deposits.

@@WATsunamidid you delete my reply with the grid reference?

@@goldfools5445 We never delete any comments. I know sometimes UA-cam makes some comments hard to find, and does actively filter some things like website links.

This is a geographical term, as the evidence studied here is not dependent on political borders. We are discussing West Australia not Western Australia.

Tsunamis triggered by undersea landslides can occur on every continental slope anywhere on the planet. Other parts of the world however have not preserved the evidence in the same way as Australia's Indian Ocean coast. The relatively sparse human population, stable and mostly dry climate, lack of tectonic activity and lack of glaciation make this a valuable region to explore this evidence.

@@WATsunami Agree completely, but the problem is none of the mainstream models include the 12000 year catastrophe cycle.

This is multiple tsunamis every several thousands of years over millions of years.

@WATsunami It even looks like the ocean floor. It's a giant plateau. Endless tsunamis wouldn't move that amount of sand and ocean creatures. It's mainly water that comes in with a tsunami, not the seafloor. I think it's a good concept, but I don't believe it's correct. Though you are the expert, so I will stand down.

... and the big one radiating from the Burckle crater

Thank you. Don't panic too much though. This needs an ice age or two to replicate. Unlike the sharks and redback spiders. You can panic about them any time.

@@WATsunami Dont worry, if I was too worried about Tsunami's I wouldnt be sailing Indonesia right now. I love a lot of things about your work here. The window onto the scale and time scape of natural forces and processes, its awe inspiring. And I also love a detective case, bringing together of clues and forming cohesive arguments. Youre work does all of these things well

@@DarwinianUniversal Thank you for the support. There was a lot of research and travelling on this one. Quite a lot of effort.

@@WATsunami Your effort will pay off with subcribers to your channel, as it did me. I have a channel. I'll try to share a link but youtube comments sharing information or links are oftern deleted. My channel theme relates to geochemistry in a way that you've never heard of before. Yes youtube wont post the channel name. I'll say hi to you from my channels profile

@@WATsunami here it is

Please watch this video as it explains things like the Perth Canyon: ua-cam.com/video/WtmIBabc7yc/v-deo.html and this video ua-cam.com/video/M_qZC8ADlIU/v-deo.html all about the Perth Canyon itself. I watched both of these videos in the research for this episode although I do not reference them directly in the credits.

Thank you. This is actually based on the geography I was taught in school in the UK during the 80s. Sand dune formation is one of the main items on the curriculum.

That is one of the locations I visited during the early research for this series. I need to go back and get some more shots with that in mind.

I think the Darling Scarp was indeed the ancient coastline. The Indian Ocean began to take its shape around 100 million years ago. I suspect the Swan Plain began to extend out westwards following the same event that pivoted the Wheatbelt rivers to the west, 5 million years ago, bringing their sediment deposits with them. The entire plain appears to be underpinned by the Tamala Limestone, which dates from the last 2 million years.

The Burkle Crater theory has been all but debunked. To create a 20km wide crater in the deep ocean at a depth of 5km takes a 6km wide asteroid coming in at steep angle. This did not happen 5000 years ago in the Indian Ocean. I will be doing a full video on this subject in the coming months. Please view our episode 5 where we triangulate the WA chevrons to the Naturaliste Plateau off the south west coast.

@@WATsunami Thank you I'll view it

Tamala Limestone. That's all there is until you hit the Darling Scarp and then you get granite.

@@WATsunami there’s got to be something ☹️ clear quartz crystals anywhere? Any pretty crystals please say yes 🙁

@ The local WA granite is fine grained and salmon pink in colour with signs of Schistosity (parallel aligning of the grains as the result pressure during metamorphic processes) and is actually very pretty. I will be discussing WA granite at length in the next video as the theme is all about where our sand comes from. I will make sure to include a macro close up of my little sample in the video.

I have a full video of the clips I took of the Avon River on the channel already, although there is no commentary it's just the drone video. I may do a video on that subject in the future, but that is not part of this current research.

@ that would be awesome since I can’t find any fossicking identification of rocks minerals around Perth or within an hour hour half of Perth only miles away like Kalgoorlie

@ I don't know if anything is worth fossicking in this region. Although the streams and rivers do flow through granite bedrock like the Darling Scarp so there is always a chance of some gold deposits. I don't know of any instances however.

I don't know that region, do you have some examples I could look at?

@ Richmond river - woodburn to Ballina Clarence river Grafton to Yamba

@ Mackey river Kempsey to South west rocks

@ thank you

In episode 5 of this series I triangulated the chevrons along the Australian coast and they point to the Naturaliste Plateau as shown in this video. For an asteroid impact to leave a 20km crater on the ocean floor in a 5km water depth would need an approximately 6km wide object hitting at a steep angle. I don't think this happened in the Indian Ocean 5000 years ago. I will be dedicating a full episode to this subject later in the year.

@WATsunami Interesting. Perhaps also look at the South African and Mocambique coastlines that also have tsunami like coastal deposits. Algoa Bay area up to Bazaruto Island a coast I have visited frequently in the past, as I have all along the West Australian coast. The sea level high and low stands are remarkably similar too.
