What was Arizona like during the Ice Age? The glacial environment was cool and moist, and nothing like the hot, dry desert climate experienced in parts of the state today. It was so much wetter that Meteor Crater held a deep, permanent freshwater lake for 40,000 years. Ice Age Arizona was home to an array of animals now referred to as the Rancholabrean megafauna, named after the Rancho La Brea fossil site, AKA the La Brea tar pits. The most awesome predator of this time was not a big cat, it was a giant Ice Age bear, Arctodus simus. Early humans occurred alongside the Ice Age animals. In fact, Arizona has six sites where the remains of the Columbian Mammoth - an extinct Ice Age elephant - are associated with human artifacts.
Dick Ryan worked as a field archaeologist in the American Southwest for ten years. He received a Master’s in Archaeology from NAU in 1983, at age 39. As an archaeologist, he worked for Desert Research Institute, the Museum of Northern Arizona, contracted with a number of archaeology companies, and was a government archaeologist with Prescott National Forest in 1987 and 1988. His main area of interest is Ice Age mammoth hunters of the Paleoindian Period. Dick has published in The Journal of the Southwest, The Nevada Archaeologist, Journal of California and Great Basin Anthropology, and Current Research in the Pleistocene. Recently, Dick has become one of the major promoters of Mata Ortiz Pottery in the U.S., while maintaining an active interest in archaeology. - วิทยาศาสตร์และเทคโนโลยี
Excellent!
This lecture came up in my feed. This was the only lecture along this line that I’ve heard. I really enjoyed it.
Thank you. Please share with other!
I am from Cochise county and have found ice age animal fossils and ice age artifacts
Wow! That is exciting. I hope you get a chance to share the location of your finds with archeologists.
So glad to find this, it has helped my curiosity about what New Mexico (where I’m from) would have looked like. New Mexico has somewhat higher mountains and higher deserts than Arizona but is similar otherwise.
Please post more kectures if you can!
Also saddened that this doesn't have more views or comments!😢
Thank you and share, share, share!
👍
Excellent
Amazing information. Absolutely fantastic lecture, thanks so much for sharing!.
Glad you enjoyed it!

I wish this was a book I'd buy it great video
Absolutely fantastic lecture, thanks so much for sharing!

Amazing information
👍
That was extremely illuminating. Thankyou
Woodland muskox, 38:35. Super cool!
The history of the US will go back much further yet 30,000 years is my guess. Than forty thousand in South America.
Sorry the history of the US cannot be older than 1776 CE.
So were the elephants eating mainly grass or trees?
Is there a link to the lichen talk that you mentioned at the beginning? I've always adored lichen, and being a Tucson native I was very intrigued to hear that more than a third of the species in North America are local to me.
Yes! Here it is: th-cam.com/video/iZF6DkYk1aA/w-d-xo.html
Thanks for watching! Please share our videos with your friends. Here is the link to the lichen talk. th-cam.com/video/iZF6DkYk1aA/w-d-xo.html
Thank you so much!
Doc, I am watching this, and smiling. I am working on a paper/book about the end of the Pleistocene and about the mammoths. Thanks for the info on the climate in AZ then. It fits wonderfully with my hypothesis of what happened between then and now. I have >100 lines of evidence. Yours adds to that.
I saw a Columbian mammoth reconstructed in a museum in Mexico. Holy crap was that TALL! I have ridden elephants. No comparison. I am very familiar w/ the Clovis story. Clovis First was bad science, led by the Smithsonian. Shame on them. Clovis was not a culture; it was a technology, passed around. More in the eastern US area. Gorgeous points. Right now focused on the Great Lakes area. Also Europe. The climate was like AZ in Oslo, Ireland, Baltic. Miami, Brownsville. Are you aware of the 200+ mammoths at the new Mexico City airport? Times Square for Columbian mammoths.
Yeah, AZ mammoths and people had a rough time when things changed. That was at the Younger Dryas. But great climate before that. Believe me, there was no ice age then. Something else.
Are those big boulders in Payson AZ glacial erratics?
No they're just resistant to erosion so they got exposed. Glaciers in Arizona likely never existed below 9k feet.
Florida was twice as big 40k years ago. Florida was gone 1M years ago.

For an ice age to occur many precise conditions are needed. Only the conditions following the Biblical Flood provide such conditions.
There was Only One Ice Age and it occurred after the Biblical Flood approximately 5000 years ago and lasted up to 700 years at best.....with many seasonal retreating and advancing.
