Alaska Mineral Resources and Brine Shrimp

Satellite data indicate potential for locating mineral resources in Alaska including tin. There has been no obvious damage to Alaskan landscapes from oil drilling in that area over the last two decades. The rate of erosion in Southern Arizona has accelerated, reshaping the region’s small canyons. ERTS data suggest more erosion in the past 60 years than in the prior 10,000 years.
