I would also point you towards the story Interactive Time-Lapse Map Shows How the U. S. Took More than 1.5 Billion Acres from Native Americans in Slate's history column, The Vault. You can visit the Invasion of America webpage directly to see more, including the original source maps that were used to make the interactive map. Below is the video version of the map from YouTube.

As my students know I've been on a map and GIS kick. Some people have asked me what historians would do with GIS. One answer can be found with the work of my students in the Digital History class where we began mapping the SBU cemetery.

Summer is a quiet time in academics. I taught History 475: World War II for the first summer session and I'm editing my book. For my students, yes we really do drafts and sometimes our first drafts need a lot of work. I've also been watching the World Cup. In the spirit of summer, the World Cup, and history here is a link to A Brief History of the World Cup from Time. If you want to get completely geeky about the World Cup, you can follow it on fivethirtyeight.com.
