    I believe this wall picks up again to the north, south of the Oregon border along the west side of I-5 at Weed, Ca We grew up with the word being "The early Chinese RR workers/scouts" made them".. but to what end? The tracks don’t parallel it! Nothing was ever considered "cleared" as there are enough rocks to triple the height, though cows will not cross what’s there, clearing land is the only thing that makes sense because they are a pain to walk through. Imagine gravel the size of saucers and thick sometimes…

    I am sorry but anybody who believes that Columbus discovered America is not a source i can trust.

  3. david beckenbaugh on September 2, 2022 at 1:28 pm

    Another odd one on the ancient Chinese maps….They depict Antarctica. So.. Just how far did they travel?

  4. Mike Smith on September 2, 2022 at 1:32 pm

    NOT conclusive! Your investigation is so flawed and has so word of mouth that it is impossible to be used as hard proof that chinese reached North America. According to the University of Minnesota Wolter’s claims to a honorable Master’s Degree in Geology.

  5. Toni Pepperoni on September 2, 2022 at 1:33 pm

    This show is underrated af i mean think about all the historical myths this legend has debunked and at least gathered lots of evidence to support the idea that the way history has commonly been taught is a lie and a coverup of what actually happened

  6. Jon Petre on September 2, 2022 at 1:34 pm

    Not one bit of proof

  7. Diane C on September 2, 2022 at 1:38 pm

    This has inspired me to find out more about the rock walls off Sierra college Blvd in Rocklin. I assumed the same chinese who worked on the Sierra Nevada railway tunnels built these walls ..because of the close proximity to the railroad. Why did they just take them apart and when? Housing started around 1999 but the walls were gone much earlier.

  8. Chad's Music Creations on September 2, 2022 at 1:38 pm

    Every spring when frost comes out of the ground as a farmer new rocks show up in your fields. Farmers for centuries made rock piles, looking at these rock walls there is fields rock free fields right next to them. Unless the Chinese came over to farm, I doubt it was them. These were done by farmers of the area working the fields near the walls.

    It was during a heavy rain of magma from your son and it’s acetament within Mercury to a passing of a cloud from out of arispic dust

    Yahshua – you know Him as Jesus – was born to a virgin, turned water to wine, taught, healed the sick, raised the dead, casted out demons, walked on water, calmed the storm, and fed a crowd of thousands with a few fish and a few loaves of bread, among many other things. He was killed on the cross as payment for the sins of all mankind, three days later He rose from the dead. Forty days later He ascended into heaven where He sits at the right hand of the Father. He is returning very soon, but before He does, Satan, the devil, is coming to pretend to be Jesus/God. Satan is an angel, and he will have certain supernatural powers with which to try to fool everyone. He will, for example, be able to make fire come down from heaven in the sight of men. He will only be on earth a short time before the real King of Kings, Jesus Christ, God in the flesh, returns. When the real Jesus comes we will all be transformed into our spiritual bodies at the same moment. Jesus came in the flesh to offer forgiveness of sins and eternal life to anyone who believes and calls on His precious name!

    if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. – Romans 10:9

    Now when Jesus was in Bethany, in the house of Simon the leper, There came unto him a woman having an alabaster box of very precious ointment, and poured it on his head, as he sat at meat. But when his disciples saw it, they had indignation, saying, To what purpose is this waste? For this ointment might have been sold for much, and given to the poor. When Jesus understood it, he said unto them, Why trouble ye the woman? for she hath wrought a good work upon me. For ye have the poor always with you; but me ye have not always. For in that she hath poured this ointment on my body, she did it for my burial. Verily I say unto you, Wheresoever this gospel shall be preached in the whole world, there shall also this, that this woman hath done, be told for a memorial of her. – Matthew 26:6-13

    Seek ye the LORD while he may be found, call ye upon him while he is near: Let the wicked forsake his way, and the unrighteous man his thoughts: and let him return unto the LORD, and he will have mercy upon him; and to our God, for he will abundantly pardon.

    To anoint your self, the sick, or a building for spiritual protection:
    Get a small bottle of olive oil and pour off a small amount into a smaller vessel like a vial or baby food jar. Use the rest of the bottle for cooking. Ask the Lord to bless your vial of oil in Jesus name. Anoint yourself with the oil by placing a dab of oil on tip of finger and touch it to your forehead, and ask the Lord to bless you/heal you. Place a dab of oil on your finger and anoint the door posts and order all negativity and evil out of the house, and order that nothing negative or evil can enter into your home including piggybacking on a person entering, order it to be so in the name of Jesus. Anoint all potential entrances to your home. To anoint the sick, place oil on tip of finger and touch it to the head of the sick and say a prayer of healing over them in Jesus name. See James Chapter 5:14-15……

    my old 1492 map shows a land route to calif

  13. Balki Bartokomous on September 2, 2022 at 1:41 pm

    Looks more like Baha than California.

  14. H P Oliver on September 2, 2022 at 1:43 pm

    If this guy actually has an academic degree in anything, it would be hogwash.

  15. kingstonerxx3 on September 2, 2022 at 1:50 pm

    Just another show that leaves you with more questions than answers

  16. Stephanie Radloff on September 2, 2022 at 1:51 pm

    I remember a wall on 11 acres of land we lived on in Hudson New Hampshire 1983 I use to climb over them when I was a kid. I jumped over ran through the woods to my friends house. I don’t know if there still there. I thought the stones were old then. I live in Florida now. Just to put it out there.

  17. Sandra Salmon on September 2, 2022 at 1:54 pm

    The Chinese went to Africa first and got their info because the Africans came to America first.

  18. KraftyKris10 on September 2, 2022 at 1:55 pm

    Yeah we already know we’ve been lied to our entire lives.

  19. Jonathan Sheffield on September 2, 2022 at 1:55 pm

    I’m not convinced the Texas wall is natural. The samples should have been taken further apart.

  20. Benny Smith on September 2, 2022 at 1:56 pm

    It seems EVERYONE beat Christopher Columbus to America!!!!!

  22. Ronald Hall on September 2, 2022 at 1:57 pm

    We were told that the contents were originally connected and through time they spread apart so back awhile in time California was in Asia I think the Chinese build them when they were connected

  23. JoeyB EZ on September 2, 2022 at 2:00 pm

    maize stone writing shows rock walls nobody knows why or who and nobody cares like those walls

  24. THE OUT OF THIS WORLD SHOW on September 2, 2022 at 2:01 pm

    Awesome Video! please check mine on, the out of this world show

  25. Michael Thomas on September 2, 2022 at 2:03 pm

    Circular stones with holes in the center like anchors used by the Chinese found off the coast of California

  26. Pensez A Moi on September 2, 2022 at 2:03 pm

    Loosely dry stacked and uncut. This seems odd for the suspected builders. I’d start with the beginning and ending points. Also, attempt to determine what was the purpose for a border in this location and not in a better location. Are there any tower outcrops or just makeshift wall? Perhaps it was to contain livestock rather than for community security.

    Interesting stuff.

  27. Roberto Rodriguez on September 2, 2022 at 2:04 pm

    Fences like this one are all over Mexico and other country’s, the manner in which people fence their properties, most likely erected by the first californios.

  28. Jade Lee on September 2, 2022 at 2:04 pm

    Is there a Part 2 to this?

  29. Kristi C on September 2, 2022 at 2:05 pm

    Call in the Time Team, and leave this storyteller home.

  30. JAlly Farms on September 2, 2022 at 2:07 pm

    wow I thought you were gonna say 500yrs ago or something but 200 yrs ago? it was probably built when some one settled there you know the land rush? if you could mark (claim) your land off it was yours as far as the eye can see

  31. Rick on September 2, 2022 at 2:07 pm

    I have seen these walls all over northern California living here for a long time most cities refuse to knock em down they build around them .

  32. Valerie on September 2, 2022 at 2:08 pm

    I grew up on a farm and I’ve been to Europe British isles and from what I see this is nothing more than people clearing the land of the rocks so that they can utilize it for grass for animals or for agriculture

  33. john bailey on September 2, 2022 at 2:10 pm

    Johnny Depp and the Pirates of the Caribbean first discovered San Francisco.

  34. TotallyShatteredVids on September 2, 2022 at 2:14 pm

    I’m shocked. I thought the Native Americans discovered America… Based on the evidence of them already being here. How can you discover something that no one else has ever discovered and talk to the people living there? It seems most likely that the people in American discovered America and someone else, who cares who, only carried the information back to the world at large. Maybe the best way to say it then is that Columbus popularized America.

  35. Bill Murphy on September 2, 2022 at 2:14 pm

    Indians mightve done it.

  36. The Proton Lighthouse on September 2, 2022 at 2:15 pm

    I’ve lived and hiked these walls in the diablo range all my life and they run deeper and longer then this episode showed. I have found them in Napa where I went to school on the top of the valley, as well as placer county where i live currently. They also exist in the Sutter buttes. If anyone has more information they would like to share. Please message me.

    Also of note. When you are on top of the diablo range you can have full view of a large percentage of Sacramento and San Joaquin valleys of California, and the Bay Area without binoculars.

  37. Traylor Kart Tech on September 2, 2022 at 2:15 pm

    Hundreds of cultures over thousands of years made dry stack walls.

  38. Roxanne Macias on September 2, 2022 at 2:15 pm

    This wall is much, much longer than 50 miles. It
    continues up along I-5 near into Oregon. You just don’t pick it up again til north of Mt Shasta, Ca. Come on up to Mt Shasta and I’ll show you. Drive up I-5 and about Montague you will find it crossing fields. Paralleling the freeway. They say the Chinese, who first came through the area working on the RR and mining were the ones who made the walls to clear the fields of lava strew rocks. See Pat Griffin’s story below in Placer Co, not far from my Siskiyou Co. Why is it a hard idea to believe the Chinese came through early 1800’s, late 1700’s maybe..

  39. FluffinMcPuffin ! on September 2, 2022 at 2:16 pm

    Even ghost ships make their way to crazy places. Anyone could move artifacts from a drifted ghost ship, wreckage, barrels etc… especially if it runs ashore. The 2011 Tsunami in Japan washed out a kasagi from a torii gate and it ended up in Oregon.

  40. Adam E. on September 2, 2022 at 2:16 pm


  41. Roxanne Macias on September 2, 2022 at 2:16 pm

    Scott Wolter it’s not gonna rewrite anything for us in California from SF to the Oregon border. The story has been long told. Why they felt to clear the fields of rock, unknown cuz the Chinese here just mined, didn’t keep cattle or horses that we know of. The rock walls would contain cattle who don’t like to cross things like that but horses wouldn’t be contained. No one thinks they are older than the 1700/1800’s. in extreme N. California.

  42. Greg Moyers on September 2, 2022 at 2:17 pm

    They were built to keep the liberals in the area. We new a new wall.

  43. Lonnie1000 on September 2, 2022 at 2:18 pm

    He finally found something !!!!

    Oh wait… this one was not a real mystery….. it is common knowledge….

  44. Rick Keifer on September 2, 2022 at 2:18 pm

    You might want to visit Chinese camp calif.there is a lot of the rock walls around there you might fined a lot of your answers there.

  45. Beth Eli on September 2, 2022 at 2:19 pm

    out of topic : the Abraham Ortillus map names Philippines in its former name I guess "CHRYSE’ which I have came across or heard of before , before it got its now name Philippines from Spanish conquest

  46. Shannon Sanchez on September 2, 2022 at 2:20 pm

    There is a wall similar to this one in ca. By lake Mclure close to Mariposa ca. I was told they were made by chinese too

  47. Segundo B. Salioni on September 2, 2022 at 2:21 pm

    Anybody notice rock walls in Ireland? Rocky place, boundaries for animals. That’s my guess.

  48. Nick Hoff on September 2, 2022 at 2:21 pm

    Chinese text blurred @15:35 ?

  49. Melvin Hunt on September 2, 2022 at 2:22 pm

    Downtown LA, and San Francisco! It’s been on the news!

  50. Diane C on September 2, 2022 at 2:26 pm

    Their was rock walls like this on SIERRA COLLEGE BLVD in Rocklin Ca. I remember asking an adult who built them when I was around 5 years old. They said the Chinese. It wasn’t until I was 40 or 50 I realized they were gone and thought what a shame that was.
