Photojournalist Kadir van Lohuizen traveled from the southern tip of South America to the far reaches of Alaska on the North American continent to explore migration in the Americas. What he found both supported and defied stereotypes, which he reported on a website and an app for iPad called Via Panam.

Landlocked Bolivia hasn't had much in the way of resources that it can sell to the world, but that could be about to change. It's home to the world's largest salt flat, which also is estimated to hold half the world's reserves of lithium — a light metal that's crucial for today's modern batteries for cell phones, laptops and even hybrid and electric cars.

President Evo Morales wants Bolivia to mine the site itself, albeit with some foreign help. If it can pull off the logistics, it would mean sending an army of workers from all over the country to a remote part of Bolivia along the border with Chile.

The area is the Salar de Uyuni, which covers 4,000 square miles and where the salt layer is at least 400 feet thick.

Bolivia started preliminary work in April 2011, employing 150 workers. But progress has slowed, in part because the site still lacks a stable electricity supply.

Kadir van Lohuizen / NOOR Due to heavy rainfall, much of the Salar de Uyuni is still covered with water. A tractor brings the workers to the experimental evaporation plant.

Japan, potentially a major buyer, recently urged Bolivia to speed up the project and meet its goal of a 6-month test run before moving on to commercial production.

Bolivia also faces competition from lithium mines in neighboring Chile and Argentina.

Still, it did get a boost in July when a South Korean company said it would help provide technology and training of workers.
