This is useful resource for exploring the changing nature of Hot Desert landscapes, and some of the desert processes that shape them.
Death Valley National Monument has changed considerably over the years, and now has a Twitter feed.
This booklet was published in 1961 and provides the perfect information for a case study of how desert landscapes change over time, and are shaped by natural and human processes. It also features photography by Ansel Adams, which is a bonus.
Would be a useful piece of work to bring this up to date, and see how some of the locations here have changed since the booklet's publication.
