Bill Neill will discuss the geological history of the San Gabriel Mountains, fault displacements, the San Andreas Fault and other local faults, the plate boundaries between the North American and Pacific plates, and the dominant rock types of the range.

This information is timeless. I enjoyed the lecture. Thank you for your work. I have a property on the east boundary of the San Gabriel anorthosite pluton and identifying rock structures in the area is very interesting to me. I am not a geologist, I am a hobby miner. I am currently looking over the rock structures at the old Monte Cristo mine. This information will be very helpful.

When we look at the topography, those with knowledge understand movement know it is very slow. We are in the middle of the San Andeas fault moving coastal CA north west. And splintering every thing on either side.

I love our local mountains. I wish they would get more snow and rain so they'd get healthier and greener. I love fact that so diverse here in so cal the topography and san gabriel and san bernardino mountains are great. Smog is killing them and fact warming with beetle bugs killin our forests trees. San Gorgonio is my favorite peak so huge beautiful. Wish all rods were takin out of our lical mountains and only hiking in by foot was the way. It would be so much healthier 4 our forests

Fish fossil found Rosedale housing development above Azusa California. When the area was studied for home development artifacts were recorded and secured by the city of AZUSA. Look up Rosedale housing development.

It is written at many place "San Andreas fault". Well, then did police catch him?

Bill Neill I Used To Live In California I Was In The Shadow of the Big One I Felt an earthquake on the San Andreas Fault on easter Sunday my dad was in the shower and my grandparents were visiting town in Bermuda Dunes Calif we would do earthquake drills at James Monroe Elementary School and Jimmy Carter Elementary School I’ve been studying the Fault for 15 years

i love all the very real comments w/ such genuine usernames. genuinely though this was very informative, though try to create some accounts or pay someone to whose sole purpose is to foster engagement within comments. It gives the illusion of a community that interacts. Comradery is a significant factor for gen z; and more people in the field is always a positive thing.

@@davedave6952 Thing is, we have an idea of how old the earth is, roughly 4.5 billion years. There are several dating methods that are used, two of the more well known are the radiometric and potassium-argon dating methods. They're commonly used to date igneous or volcanic rocks. The carbon dating method is used to date organic material that once belonged to living things like bones or teeth. If you want to trust in the Bible, I'm not going to stop you. Though you're going to have to accept that the earth is a circle, yet has corners, is supported by pillars that stand on water, has a firmament that's composed of some unknown material that holds back an infinite amout of water, that the stars and planets are just dots on this firmament.

@sigisoltau6073 3 ай бұрын

@@davedave6952 Well we know the earth's age fairly accurately. I say that because most of the earth's oldest rocks have been destroyed by tectonic forces or erosion. Those that remain have been dated to 4.3 billion years, 8n Australia zircon crystals have been dated to 4.4 billion years. So the earth is at least 4.4 billion years old, if you don't count meteorites. Meteorites are from space and the solar system, but since the planets formed from them, you can date them as well. Meteorites as you know have different origins, those that came from asteroids are about 4.5 billion years old, those from planets are slightly younger.
