This video is great. You should be proud of this. It is no easy task to easily explain these concepts to students. You have done the education field a great service and whoever you made this video for should be proud of your accomplishment.
The cracks in the granite are not faults, but joints. Completely different things. Faults involve movement, or shifting, of massive parts of the Earth, while joints are the localized splitting of rock associated with the release of built up internal pressure. Exfoliation is one type of jointing. Most jointing, though, forms vertical joints--also very much visible in Yosemite and the Sierras. Additionally: Faults can be huge and visible, as the San Andreas is, or small and deeply buried, as around New Madrid, Missouri.
I was lucky enough to have my mind blown by Yosemite this past week. I think I watched all the videos and this one’s my favorite as far as a good explanation of how it all happened. It’s an amazing sight to see.
This is a great video. I like you message. You made it about Yosemite not about you. You delivered the information at a good pace and with pictures that demonstrate what you are saying. Thank you very much!
not far from Truckee and Soda Springs. i know of a cirque type canyon but with odd pumice formed in piles almost like stalagmites. i haven't seen anywhere else in the Sierra, and wish i knew how they formed.
You've done some good work here but one criticism: DO NOT show a diagram or picture for less than a second!! This is a flash, way too brief for people to understand. Your viewers cannot begin to comprehend a diagram or picture when it is shown for less than a second or even a couple of seconds. Either show it for long enough for viewers to comprehend it with sufficient narrative explanation or else just leave it out. That said, you still give some interesting info here. Thanks for making this video.
Thanks, Kari. Nice overview of how the Sierra was formed as well. Now I know why it takes so long to get to Donner Summit from the CA side, and why it's much quicker to get to from the NV side.
