Around the world glaciers are retreating or disappearing entirely almost everywhere, with the notable exception of the glaciers in the Karakoram Range, most of which are either holding steady or actively growing.

The so-called Karakoram Anomaly has been the subject of intense study with in-depth studies appearing in scientific journals.

Was geomapping from the northeast of Alpine, then, saw this.

Lake Providence, Louisiana is an oxbow about six miles long in an abandoned bed of the Mississippi. The river took the town more than once, and each time the people moved, so today's town is on its third site.

In 1944 geologist Harold Fisk put out 15 maps for the Army Corps of Engineers showing every old course of the lower Mississippi he could find, from Cape Girardeau, Missouri, down to Donaldsonville, Louisiana. He and his team spent three years on it. They worked from deep borings drilled by the oil industry, engineering maps and fieldwork with Richard Russell, and the goal was to work out how the whole valley formed and how the river got to its 1944 course.

In the lidar the lake is the curved band from the top left toward the right, and the town's street grid is on its south bank in the lower right. The field lines on the left bend with the old channel. My own render of the lidar. Fisk's maps squeeze thousands of years of channel shifts into one picture.

Hello!

I am a land Surveying student whos (heavily) thinking about changing to Geography.

I went into land surveying thinking that I could help the environment and conserve land and I've found that Land Surveying is just working for construction projects and developments.

That is not what I want to spend my life doing.

I want to conserve land across the earth, not make it easier to sell it or build on it.

Since I've been studying this major (2 full years now) I have made it my mission to find any Land Surveying professional that has a job or an interest in conservation or helping conserve land and not one of them has.

I know that their lives aren't mine, but its very discouraging.

I have been doing my research on Geography and so far I've loved the possibilities a degree in Geography brings. I've talked with a Geographer on linked in and he even works in disaster recovery which is so so amazing.

To further my research I would love if any Geographers or knowledgeable people could tell me about different jobs in Geography and what you all do at said job/what are your experiences.

( I highly encourage anyone who replies to give as much info as possible I will appreciate everything you have to say)

Recently I discovered the term urban hierarchy, which ranks cities in an urban area based on things like population, economic centrality, and interdependence. This sounds exactly like what people often debate when it comes to the cities in my region, Northwest Arkansas.

Northwest Arkansas is the 9th fastest growing metro area in the United States over the last year. Its four principal cities within a ~30 mile corridor are:

- Fayetteville (107,000 people): home of the University of Arkansas and the region’s cultural center
- Springdale (91,000 people): home of Tyson Foods (Fortune #87) and the region’s industrial center
- Rogers (77,000 people): home of Pinnacle Hills, the region’s commercial center that was created \\\~20 years ago by JB Hunt (founder of JB Hunt Transport Services, Fortune #371)
- Bentonville (63,000 people): home of Walmart (Fortune #2) and the region’s corporate center

The region doesn’t fit neatly into a conventional central city surrounded by suburbs model as it’s polycentric. But people can’t seem to agree on the region past that - is Fayetteville or Bentonville the main city? Both? Neither? Maybe all 4 principal cities?

So what do you all think? Whether you know of or have been to the region or not, I’d like to hear your thoughts.

My two starters:

Mercator. Greenland looks like it could swallow Africa, when Africa is actually about 14 times bigger, roughly 30 million km2 against Greenland's 2.2 million. Africa is big enough to fit the US, China, India and most of Europe inside it at once, and the standard classroom map hides that completely.

And the quieter one: north being up is just a convention. Nothing about the planet says Europe belongs at the top, flipping the map changes nothing except how wrong it feels.

What is yours? Bonus points if it is something other than Mercator, that one has had enough attention.

There is a website where I can search for city suffix and prefix, the website has a dark overlay and the points were blue I suppose. For example if I wanted to search for rivers place names with "Mae" in Thailand it was able to display it on a little map. But german citiy names ending on like -stedt or whatever was possible. I think there was a heat map too.

Hopefully someone knows the website.

Hopefully I wrote this correctly and its understandable, if not let me know.

For example, people point out Hawaii as an example of why states don't need DST. However, they have basically 12-ish hours of sunlight throughout the year. Alaska has 19 hours of sunlight near Anchorage in the summer and 5 hours in the winter. I would say for both of those the time change does not really seem needed.

Compare that to Minneapolis, Minnesota where it's 16 hours in the summer and 8 in the winter. So an argument for the time change in Minneapolis, Minnesota has a better argument.

When I have asked other people about where the time change makes sense. The answer I usually got from Denver, Colorado in the south to Saskatoon, Saskatchewan to the north.
