The recent TV documentary on the Dust Bowl by Ken Burns (PBS) was based on the book by Timothy Egan: "The Worst Hard Time" A book that's hard to put down. Order @ Amazon or see if you local library might have it.

Interesting set of photos. I grew up in Eastern Colorado. Except for the sand drifts the trees and older farms still look like that. My cousin works with the BLM in Clayton, NM (Image 17). I didn't notice if she or the office got credit in the PBS film but they worked with the film crews when they were in that area. After visiting them back in 2009 I drove over to Dalhart, Texas (Image 14) about 30 miles away. Then up through the panhandle and into Colorado. Thankfully 70 years have repaired the land.
