Raised Relief Prominence Maps for Kansas and Saskatchewan *1,2

With all the talk about the flatness of Kansas and Saskatchewan, I decided to take a light technical look.
Using the SRTM30 data, I generated a shaded relief map for both -

The Kansas map goes from 37N to 40N and from 9440'W to 102W. The Saskatchewan map goes from 49N to 60N and from 100W to 110W. The Saskatchewan-Manitoba border varies from about 102W to 10130'W; I chose not to clip Manitoba from the map because the Manitoba prominence winner may be showing.

Both Kansas and Saskatchewan are shown at the same scale and with the same degree of shading. Saskatchewan is by far the more interesting! Most notable is a northwest to southeast - trending line of mesas sprawling across the eastern border of the province and on into Manitoba, and as noted in a previous message by Mike Cleven. Each of these mesas has about 1,000 feet of prominence.

I ran a cursory prominence analysis of Saskatchewan (and western Manitoba). Peaks with over 500 feet of prominence are shown as olive triangles, and their saddles are green circles. The results are listed below. When a number shows up in the "Off" column, it is the prominence to which the peak might be lowered by rising terrain outside of the area included in the analysis.

In a few cases, the peaks and/or saddles are ambiguous because of their apparently equal heights. Thereby I cannot tell which is the true prominence winner, and, as such, I listed all possibilities. I was able to identify only a handful of the peaks using an atlas, and I leave it to our Canadian contingent to continue the work.

MB = Manitoba, ND = North Dakota, SK = Saskatchewan
