I sure like your way of teaching the layman , (that would be myself) sends the imagination back millions of years in a matter of minutes. Thanks for all you do.
Thanks for your kind words. I love to share the Earth's stories with others in a straightforward and understandable way. Thanks for watching and look for more videos coming soon!
Great Video! I would have guessed the Rain Shadow effect from the Panamints causing the difference in alluvial fan sizes. Your explanation is perfect! Thanks!
Luv the library editions of your videos. At 3:07 I would add the alluvial fans are also affected by the availability of rainfall. Here the Panamints (being farther west in the W to E storm tracks) gets more snow/rain than the eastern side of DV (the Blacks), so more material can be transported over time.
Exactly. As adjacent alluvial fans grow and coalesce, it forms a bajada. If the mountain is no longer uplifting, eventually the bajada can cover most, and eventually all of the mountain with sediment.
I like to imagine the amount of geologic rainwater as a layer. Death Valley at 1"/yr gives for a millennium 1000"/Kyr, or say ~100' of water pouring off the landscape.

Great video! I was just in Death Valley and saw these. I look forward to going back maybe in a year or so. So much to see and learn!
When I was younger, (Dryas), I used to love exploring the alluvial fans of all of the valleys in the western states. Thanks for this video Shawn.
Nothing beats a nice diagram! Very helpful, thank you Shawn :)

THANK YOU!
GREAT BREAKDOWN!!!
What exactly is a bajada? Is it basically alluvial fans that have overlapped?

2:13. Shawn's distant shot of the Panamint Range shows a classic example of a bajada.
Alluvial fans are my favorite kinds of fans!

Well explained thanks.👏
Then a great deal of these mountains is already scattered over the valley plains.
Whoever thought of the name for Death Valley had no sense of humor.
