What are Rill Marks?
Rill marks are distinctive patterns formed on sandy beaches as water flows downhill after the tide has fallen.
As the tide rises over a sandy beach, the gaps between the grains of sand fill with water.
When the tide starts to fall, this water is pulled down by gravity. Much of the surface water washes over the top of the sand and returns to the sea, but some water remains deep in the sand itself.
Gravity pulls this water vertically downwards, not towards the sea. As this water travels down it meets a layer of impervious clay or stone. This water then starts to flow downhill over this barrier until it emerges further down the beach.
As the water trickles out over the sand it creates channels. They are distinctive and ‘dendritic’ - they look a little like trees. These channels are called ‘rill marks’.
More info on beach patterns in my book, How to Read Water.

The Meaning of Spines on Holly Leaves
zhlédnutí 798Před rokem
Spines on leaves are a defensive response. The more spiny a leaf is, the more likely there are grazing animals nearby. This is also why spines on leaves in gardens are common - the plants are trying to defend against the gardeners blades.

I just discovered this channel and you. I love.. Do you just know that your wind blows in the south west?
I notice that too -- whenever we get an ozone advisory which means a temperature inversion I hear distant trains and roads.
Please make some more longer videos if you can! Or videos about clouds!! I have your books and i love them, but it would be great to listen to a video and get more real life examples. Especially incoming weather and such. Take care 🙏
I am an Earth Science teacher who was today years old when I learned how to really read a tree in snow! You, sir, are too ingenius! I was noticing only a few thousand are subscribing to your channel. I feel like I have found a true treasure in the midst! Sharing your channel with my students will be a joy this year so continue to keep the teachings clean, Thank you!
Stop speaking 😂 i try to hear the wind
Don't quite get it. You see you're at the edge of the woods and therefore you're able to read the clue in the trees that you're at the edge of the woods??
I believe he is saying that typically there is a rule that the longer, more horizontal branches can be used to determine which way is South. However, that may not be the case here because this tree is on the edge of a woodland, so it is likely to have these horizontal branches so it can reach out into a more open area. So he's saying you cannot always rely on the rule; you have to take it into context.
Could I use this daisy footage for a music video clip please? See the demo at the end of this clip. Thank you! czcams.com/video/VSuwZPhPi0M/video.html
Huge fan of you work. I've read "lost art of natural guidance" and I was in awe. I love to camp and bushcraft and had no idea of most of what you taught me. However, I'm from the south hemisphere (Brazil) and I would love some guidance over south guidance and plants. But your videos now give "visual hints" onto what have been mostly words. I have been taking my notebook and trying to take notes over sunlight, air moisture, which plants were there. Would you reccomend me some guides to know plants names? Even tho I live and grew in Brasil, the "cerrado" biosphere is very diverse and have an infinitude of plants. Thank you so much for this new type of knowledge that I've found myself in love with!
What the heck is a fetch
Love your book I'm reading for school, even though it was made upside down and backwards, lol.
Ok, the sky is beautiful in this video, lol.
Is there any geographical restriction? Is this possible in Oceania? Thank you.
Still don't know what's fetch
Awesome, always learning with Tristan.
I'm about 50 pages into this book and am loving it. I'm learning so much. Thank you for writing it.
Thats the tooth gap on the left wing they trying to break the wind barrier 😂
Very interesting how it seems like the clouds then seem to disapate again over the hilltop after forming!
I don’t know how I got here but I don’t mind it
Got lost trying to read those darn lying trees
Very interesting
Loving the book Tristan!
I Lichen them to a compass.
LETS GO LICHENS LETS GO
I always go Lichens
NÃO ENTENDO SEU IDIOMA. SEI QUE É PLATIU. AQUI NO BRAZIL JÁ EXISTEM FAZENDAS. JESUS ABENÇOE GRANDEMENTE. 🙏❤️💥💞 🇧🇷🌹🎉🌹🎉🌹
Hi Tristan, is this the same regardless of one’s location on the planet? Eg southern vs northern hemisphere vs equator. Thanks
No this would largely only apply to northern latitudes.
@@eldaytripper2 I figured so. Thanks for confirming
I have springed to life
Where in the world?
Awesome Tristan, How to Read a Tree arrived today and looking forward to getting started on it!
Excellent info as always. Great stuff, can't get enough of your books.
Thanks!
Always carry a log with you. 😄
Don’t you mean a towel?
I wish i had even just a drop of your knowledge.
Love it sir!!! I learned land navigation in the US Army in the late 60s. After getting out of the Army I spent many years hiking & backpacking into the wilderness. I carried a US Army compass & 2 backups. I carried rolls of maps in an aluminum tube. Not many people can do this these days.
Excellent info Mr Gooley. I really admire and like your books, reference them continuously.
Awesome, pre-ordered and looking forward to it!
Cheers Tommy!
Man you're amazing. My father loves nature, spends most of time in mountains and forests, but he realy hates technology and smartphones :D With these books of yours, he'll finaly be able to predict the weather, know cardinal points and so on without the need of pesky tech gadgets that he can't use!
Really enjoying these videos and am currently reading through your previous works. Thank you for keeping this knowledge alive and passing it on to future generations!
I come here as I was researching why I always hear train noises at night. This is very peaceful and lovely. Thank you.
Love this as always , simple and highly effective
Do more about snow please!!! Like snowflake size, wind ect
Foggy.
It's in the book!
Fascinating vid. Thank you. Amazing how much helpful information you shared in 1:30 minutes. New to your channel. Love it!
Shame the British government didn't listen to this a few days ago...
👍👍
Thank you for sharing. 🙏
Thank you for sharing! Are the signs (in this video / book) applicable in other parts of the world too? Say South Asia?
Focused on north temperate zone, but there are quite a few insights that apply globally, especially at the microclimate level.
That is just a brilliant insight! Thank you for sharing that with us. 👍🏻👍🏻👍🏻 Love it!
Thanks!
Thank you for sharing your vast knowledge of the world around us. These little signs and clues are fascinating and I can't wait to read your other books. I'm still making my way through The Walkers Guide To Outdoor Clues and Signs, I have to read it in short stints to fully take it all in because it's just so packed with information. Keep up your amazing work.
Thanks!
Remember to correct when going from northern to southern hemisphere nations. Guy roots can also assist if you know which direction strong winds predominantly gust in,
Loved the book. Just moved to Richmond. Looking forward to finding the six city winds. 🙌
