This week on ARIZONA SPOTLIGHT, with host Mark McLemore
-A new study issued by UCLA says that work done by undocumented migrants is expanding the Arizona economy to the tune of hundreds of millions of dollars each year. But, critics say the state still spends more on public services for these undocumented workers than it can collect. Steve Shadley takes a closer look.
-A group of high school students in Tucson recently traveled to the tundra to help scientists from National Geographic collect samples of life in the Colorado Rockies. Fernanda Echavarri talks with the teens about what it was like to camp and do field research at 11,000 feet above sea level.
-And, over two million years ago, the area that is now Safford, Arizona was a swamp that was home to a range of fascinating creatures, many of whom left behind their fossilized remains. Mark McLemore talks with a scientist involved in a Bureau of Land Management project that has recovered a complete glyptodont, a huge, armored herbivore that was a predecessor to the modern armadillo.
