Spotted on Strangemaps is a great post about John Westley Powell’s Report on the Lands of the Arid Regions of the United States, which presented an alternative to the orthogonal public land survey system dominated boundaries of the western states. Since Owens Valley is a reoccurring topic here on InfrascapeDesign, it’s rather fascinating to see Owens lake and the outlines of the Pleistocene Lake Manley that are discernible in the larger versions of the map (see below).

A larger PDF of Powell’s map is here from the aqueousadvisors, who credits William deBuys’s book and the USGS annual report for the reproduction of the map. Other posts about Powell’s map on ecopolitology, & good.
