As someone obsessed with this mountain and its climate, past and present, my jaw legitimately dropped when I saw the thumbnail. I love looking at the cirques on Baldy on Google Earth, and to know there were glaciers only 2,800 years ago is so indescribably fascinating to me!
From 1968 to 1976, my family often traveled from Albuquerque to Los Angeles, via I-40. There was a lot of attractions left over from the days of "Route 66." One of these was a hole in the ground with "the remnants of a glacier" (how the roadside sign advertised it). Curiosity overcame us on one trip and we stopped to look, it was underwhelming. A year later, the attraction was closed.
Definitely appreciate the discussion of AZ geology. When I hike/bike/drive here I always find the different patterns fascinating. I would love a AZ Playlist.
Fun fact: The San Fransisco Peaks are usually cited as having the only timberline in Arizona, but Baldy has a timberline as well (just barely, hence the name Baldy).
Yes that is the real temperature here. Shine that infrared laser on anything chrome or the metal rims on your car & it's 160°F - 170°F. Great info, glaciation made Mt. Baldy bald lol.
Interesting. Mount Baldy is in the White Mountain Range of Arizona. The original Sierra Nevada mountain range was a vastly-ancient volcanic island arc landmass dating as far back as 250-100 MYA. The original Rocky Mountains volcanic island arc landmass of Laramidia subcontinent was formed 80-55 MYA. The Farallon plate moved under the ancient Laramidia, pushing and uplifting the Rockies and the northern mountain and Midwest states as far as 1-2 miles in elevation during 60-40 MYA. The Pacific plate moved northward cutting through and fracturing the Farallon plate, pushing those remains to the western and eastern slopes of the Rockies, with further uplifts of the Rockies, and the Colorado Plateau in the 40 MYA period. The modern Sierra Nevadas were formed 40 MYA. The White Mountain volcanic and mountain range was scrunched and uplifted 30 MYA.
When Fall arrives but summer doesn't want to leave you get a fifth season for the year called Fummer. It's 12:30 here at my house in the Phoenix metro area and it's 104 degrees and still climbing and the forecast is apparently Fummer is here to stay for a while.
How do we know the height of a extinct volcano that last erupted 8 million years ago. I assume very complex math equations. But im curious if you could offer a quick explanation.
Like white asphalt roads? Maybe, as white coloration can't be that expensive. Less asphalt roads would be even better, the sprawl on this city is particularly bad
I'm not super familiar with Arizona geography, but I've been reading about USGS work in the Sky Islands area (I think this is near there?) and some ecological restoration there. The USGS work is more hydrology than strictly studying rock units (obviously they do that too) but it's neat.
Baldy is just outside of the Sky Islands because it's connected to the plateau. You can actually see Mt Graham (the largest sky island) from the White Mountains.
Wasn't that whole mountain complex part of one giant 16,000 foot mountain, Mt San Francisco where the San Francisco peaks are today, I think it collapsed about 200k years ago.
My work used to send me to Sunrise several times in the 90's. It was always winter & there was a whiteout blizzard every time. I was not surprised to learn of the glaciers.
Life on earth is so much harder during ice ages when life flourishes on earth when it’s very warm. So there’s nothing to worry about with earth getting warmer.
The issue isn't so much the trends in temperature, but rather everything else humans have done to the planet along with it to make it much much harder for life to adjust. We can't afford any major changes to Earth's climate now. A glacial period would probably be equally catastrophic (many warmer and wetter refugia would suddenly become very crowded and degraded) but that doesn't mean current trends are _good,_ maybe in absence of humans but that's not the current reality. Also, humanity is kind of a product of the Quaternary ice age, so ending that (we're still technically in the ice age, just an interglacial period but the way things are going the entire ice age itself might terminate) would be a really bad idea, humans are just meant for a cooler world. I do think that the arguments of warmer = worse are rather simplistic, but that doesn't mean we're not in a bad situation
Always wondered about it. I thought it was part of the Springerville volcanic stuff. It really is amazing how much volcanism there has been in AZ.

I always wonder if Mt Graham had one
Thanks for all the hard work on these videos!
100 degrees F before noon? Ah, perfect fall weather. You can just hear the pumpkin spice turning to ash.
My brother and his wife live near Mt. Baldy! Thanks for the details! I sent the video to them
30th thumb up saying hello to all fellow armchair Geologists. 👍
2 hours later I am no 500. Seems that many people are interested in this. And seems as if GeoHub is doing a good job.

For a minute there I thought you were going to talk about Thunder Bay's Mount Baldy!! (Ontario, Canada)
I hike the loop every summer. Thanks for the history lesson!
I grew up in Show Low a town not far from Mount Baldy. Some of the biggest pine trees and untouched woods in that area it is a special place.

Could you cover the quartz crystals of Diamond Point, Arizona?

I'm down in Tucson - I noticed the road was melting at an intersection the other day.
What was Arizonias last volcanic eruption?
Sunset crater, it erupted about 900 years ago.

Time travel
You would think Arizona would make roads that reflect more light to keep the temperature down.

Well, the best you can say, is At least you are not in Tucson. ; )
I think I saw a bald teacher with a green shirt hitting me with a ruler on top of that mountain...
Thanks as always, Geology Hub!
Glaciers in AZ! Awesome.
I love your videos ❤thank you
Yea I agree born and raised here and yikes.😅
that intro was silly, loved it! 😅
Mount Baldi Basic's
Nape
Why would anyone try to grow a grass lawn in a 37C/100F desert????
Because it's the single family home ideal in the US, even in the desert. These rules don't take climate into account.
Life on earth is so much harder during ice ages when life flourishes on earth when it’s very warm. So there’s nothing to worry about with earth getting warmer.
Wow the amount of stupid in your comment is too much to unpack.😂
Aside from expanding deserts, rising sea waters due to polar ice melting, and loss of fertile areas for a population that is growing, I guess not!
@@blueandgreenslacks I tried to unpack it myself...
