| Why does this article have a picture of the Maroon Bells? As opposed to something along Green River or, ideally, the 700m deep canyon being described? |

You'll get something about climbing a mountain in the Andes and keep getting shown completely misleading pictures of Himalayan mountains, etc. | | |
| ▲ | dylan604 an hour ago | parent | next [-] | | The content you create is only as good as the stock footage you have available to you. It's not like these people are trekking to the locations to acquire their own content. If you search in stock libraries for mountaineering in the Andes, and it only brings you footage from the Himalayas you're just going to use it. | |
| ▲ | gedy 2 hours ago | parent | prev | next [-] | | I think it's largely because they are "content creators" instead of trying to tell a story or share information. | | |
| ▲ | indoordin0saur 2 hours ago | parent [-] | | I'll notice this with TV documentaries and segments on news channels quite frequently as well. I have the "GeoGuessr gene" as well as being decently well travelled so I spot this stuff all the time. One particular pet peeve of mine is movies or shows mean to be shot in medieval Europe but the "forest" they use is actually a tree plantation of North American native trees such as Sitka Spruce. |

| ▲ | PyWoody 3 hours ago | parent | prev [-] | | Simple, lazy stuff like that always drives me up the wall. The HGTV show House Hunters used to be wildly inaccurate with their map location pins. On more than one occasion they'd say a couple is from the Bay Area but when they show the map the location pin would be in LA County. Like, come on. That's not even close. | | |
| ▲ | toast0 an hour ago | parent | next [-] | | There's a lot of duplicated geographic names in Northern and Southern California. If the production house isn't in the area, it's hard, close enough. I lived in Burbank, but I was in the unincorporated area of Santa Clara County, not the incorporated city in LA County. Incidentally, I was living in the South Bay, but not the South Bay in LA County, or the South Bay in San Diego County. Anyway, perhaps the couple is from the Bay Area, but their house is in LA County right now. :P | | |
| ▲ | PyWoody an hour ago | parent [-] | | A specific one that I'll never forget was actually a House Hunters International episode. It was years ago but the pin being off by about 400 miles burned it into my memory lol I think they were moving from Market Street to Amsterdam. |
| |
| ▲ | dylan604 an hour ago | parent | prev [-] | | Maybe the pin was closer and they were lying about it being in the Bay Area??? Also, no need for exact location for these pins. The new home owners probably are fine with it not being exact |

| For people interested in the subject generally I highly recommend John McPhee's anthology "Annals of the Former World." Actually I highly recommend everything John McPhee has written but this is a good start :). |

| ▲ | arethuza 4 hours ago | parent | next [-] | | I can also recommend: "The Earth: An Intimate History" by Richard Fortey | |

| ▲ | pengaru 3 hours ago | parent | prev [-] | | References to his books should carry a warning - something to the effect of: "may inspire circuitous road trips involving many stops dangerously examining road-cuts on busy interstate highways" | | |
| ▲ | jhundal 44 minutes ago | parent [-] | | I would pay good money for a field guide/itinerary to accompany "Assembling California". More directly related to the Green River, I found Wayne Ranney's "Carving Grand Canyon: Evidence, Theories, and Mystery" an accessible/engaging intro to deep geological mysteries. |

| Fascinating to think of entire mountain ranges moving up and down like the skin on a wobbly pudding. |
| |
| ▲ | SideburnsOfDoom 4 hours ago | parent [-] | | And the speed at which it happens: > a cold, round anomaly about 200 km below the surface. > By estimating how far the drip had fallen and calculating the speed of its descent, the researchers estimate that the drip broke off between 2 and 5 million years ago. A few megayears later, the bit that broke off is still falling. 200km in 2m years, I make that in the ballpark of 0.1m per year - a bit less if it's > 2m years, and started below the surface. |

| What about ice pressing down? The repeated glaciations might have pushed in area down and back up several times over 6 million years. Might have even caused that drip to break off. |

| Can we take a moment to appreciate that Dr. Adam Smith works at the University of Glasgow? |
