Summary

Description
English: Based only on that PNG image. I made this file primarily using QGIS, and the following public domain [

https://www.census.gov/geo/maps-data/data/tiger-cart-boundary.html shapefiles from census.gov]:

cb_2015_us_state_20m cb_2015_us_county_5m

The map projection is:

NAD83(2011) / Texas Centric Albers Equal Area

+proj=aea +lat_1=27.5 +lat_2=35 +lat_0=18 +lon_0=-100 +x_0=1500000 +y_0=6000000 +ellps=GRS80 +units=m +no_defs

The original PNG, rotated and scaled slightly to fit this version of the Albers EA projection, is in the image for your comparison.

The approximated areas of the Dust Bowl were traced from the PNG in InkScape, no shapefile was made or used.

This is definitely the current crown jewel of my Wikipedia images. It took the longest to research and make and it took lots of software. But it was definitely worth it - this map has been requested by readers of w:en:Dust Bowl three times. Someone had to deliver eventually.
