Having spent many days in the Clarno area in July it's hard to believe that area was ever high in humidity at anytime. Your going to have to get back to that R19 episode in time and explain that.
The quick explanation is that when you look back in time, magnetic field reversals are recorded in volcanic rocks like the Mid Atlantic Ridge. R19 is the 19th reversal (north pole becomes south pole) back in time, dated to about 42 million years ago.
While the articles you see online tell of doom to come, magnetic reversals happen very very slowly over hundreds or thousands of years, and is never like flipping a switch. The only geologic events which happen on human time scales are earthquakes, glaciers, landslides, and volcanic eruptions; and the Earth's magnetic field is constantly observed and studied by the USGS and NOAA, so any major changes would be known a long time coming If a future magnetic reversal is something that interests you, I will defer to someone who has done far more in-depth research on this topic than I: skeptoid.com/episodes/4728
I have a large conglomerate rock, I wanted to send a picture but couldn’t figure out how to include it in the comments. Anyway, would you please tell us about how conglomerates form? I study the rock a lot and wonder how it happened. The rock is a little bigger than a basketball and is dark green. It has many sizes of rocks in it, granite, some rounded river rocks, black rocks and small green rocks. I am very curious. Thank you for your channel. You are very informative.
The presence of river-rounded rock should be a tip-off to its formation! Clearly, moving water deposited rocks which cemented together (Called lithification) over time. Often, conglomerates are found from ancient alluvial plain/river systems or from ancient deltas where rivers entered the sea.
The only thing I disagree with you about is the years. I am a Christian so I differ on the time line, but I enjoy your videos and I'm looking forward to seeing the new ones you bring.
Short, simple, and informative. Thank you, Andrew!
Glad it was helpful!
Great job! I really enjoy the channel, great info. Can’t wait for more!
Awesome, thank you!

Yay! Clay!
Thanks for unraveling more geo-mysteries. Some people think we’re due for a magnetic pole reversal within a few more decades?

RX 7 FTW
Thanks for your help Craig!
I wish your videos were longer and. not like short commercials
Luckily, there's a whole bunch of them for you to watch!
