I've been going through all of your videos this last week. So informative that I have started to take notes. Thank you for providing this information for all those interested!
Very well put together video. I love GUMO. But don't know much about the geology other than its a limestone reef. I'll be going back through your video a little slower. A lot of info in there. Thanks for all the work putting it together.
So I am curious about the uplift and/or uplift events in the area and their time frame; specifically - I have seen competing maps which will stop the Rocky Mountains at Albuquerque and others have the Rockies extend down to El Paso and include the Guadalupe mountains. I speculate that the Rockies are defined by the Laramide orogeny but the mountains extending passed the Rockies into Mexico must have distinct uplifting events. In any case, driving south through New Mexico into Texas - it just looks like mostly mountains all the way down.
Fantastic question! "Rocky Mountains" as a physiogeographic province could include the ABQ and ELP regions... it's often just used to talk about mountains located more inland than the Sierra Nevada and other more coastal mountain ranges. Geologically, you are correct that the Rocky Mountains are generally associated with the Laramide Orogeny. Unfortunately, there is a bit of a terminology/language disconnect between geologists and how normal people use "Rocky Mountains." Geologically, the Guadalupe Mountains are not considered directly related to the Laramide Orogeny. The uplift there (as well as most of central and southern New Mexico) is a result of normal faulting that occurred during the Late Oligocene to Early Miocene (ca. 25 Ma) and is generally attributed to crustal extension and opening of the Rio Grande Rift.
Dr.Chapman, please continue this national park geography series. It’s amazing!!
