Plate Tectonics and the Formation of Central America and the Caribbean

This animation is made from a time series of maps reconstructing the movements of continental crust or blocks, as South America pulled away from North America, starting 170 million years ago. Note that South America is still clinging to Africa at the beginning of the series.

The land bridge connecting North and South America is hardly permanent (on a geological time scale that is).  This video is an animated version of the still maps from this article.

Urban Farmers Say It’s Time They Got Their Own Research Farms

The University of the District of Columbia is the one land-grant university in the U.S. with an urban focus. It’s leading research on growing food in raised beds, hoop houses and shipping containers.

Utahns, Mainers and Wyomingites: The ultimate guide to what to call people from each state

“For most states, you’re safe adding an –n, and maybe a few other letters, to the state’s name – a la Coloradans, Nebraskans and Californians. For three states, Wyoming, Wisconsin and New Hampshire, the correct method is to add an –ite. For a handful of states in the northeast, the style is to add an ‘r’ – New Yorker, Vermonter, Mainer, Marylander, Connecticuter and Rhode Islander.”

Having lived in New England for 6 years now, I still haven’t found a polite term to refer to people from Massachusetts.

The Chinese Art of the Crowd

After viewing news photographs from China for years, one of my favorite visual themes is “large crowd formations.” Whether the subject is military parades or world-record attempts, mass exercises or enormous performances, the images are frequently remarkable. The masses of people can look beautiful or intimidating, projecting a sense of strength and abundance. Individuals can become pixels in a huge painting, or points on a grid, or echoes of each other in identical uniforms or costumes.

Before-and-after maps show how freeways transformed America’s cities

Beginning in the 1950s, cities demolished thousands of homes in walkable neighborhoods to make room for freeways.

At the time, this was seen as a sign of progress. Not only did planners hope to help people get downtown more quickly, they saw many of the neighborhoods being torn down as blighted and in need of urban renewal.  But tearing down a struggling neighborhood rarely made problems like crime and overcrowding go away. To the contrary, displaced people would move to other neighborhoods, often exacerbating overcrowding problems. Crime rates rose, not fell, in the years after these projects.  By cutting urban neighborhoods in half, planners undermined the blocks on either side of the freeway. The freeways made nearby neighborhoods less walkable. Reduced foot traffic made them less attractive places for stores and restaurants. And that, in turn, made them even less walkable. Those with the means to do so moved to the suburbs, accelerating the neighborhoods’ decline.

Later this month I will be in Cincinnati (pictured above) and will see firsthand some of the urban changes that freeways have had on the landscape, neighborhoods, and the lives of residents.  This article has some “swipe” aerial photography on Cincinnati, Detroit, and Minneapolis for your analysis.

In a flat landscape, what represents power more than a towering mound?  My family loved our excursion to this site and it show so many geographic issues.
