On her website the author has a post about inspirations for her in writing the book which include landscape photos - http://www.diannewarrenauthor.com/book-inspiration/
The book opened with a 100 mile horse race from pioneer days much of which took place in the Great Sandhills. The same sandhills were in the contemporary part of the book.
Tourism Saskatchewan describes them:
The Great Sandhills of southwestern Saskatchewan are a unique 1900 sq km area of active desert-like sand dunes. Native grasses and small clumps of trees such as aspen, willow, and sagebrush flank the dune formations. Mule deer and antelope frequent the area.
Some dunes reach 15 – 20 metres in height.
In addition to wildlife several thousand cattle are pastured in the hills for several months of the year.
Oil and gas exploration takes place in the hills.
About 20 years ago our family had a summer trip around the province which included a stop in the Great Sandhills. Used to either bush or prairie it was an unusual experience to climb up the pure white sand hills and feel we were in a desert.
Warren’s photos above capture those hills which often have grass and/or trees at the base of the dunes.
A huge rock is further featured in the book. Buffalo and now cattle rub up against the rock. While rocks are not special in much of the world they are a rarity in the prairie.
Warren provides a photo of Standing Rock, a large rock on the prairie near Hazlet, Saskatchewan. It is a glacial erratic and stands out in a plain. In fact, it was used as a landmark by settlers of the area. It is 3.35 meters high and 9.14 meters long.
I have been to Hazlet to play Twilite baseball but I have not seen the rock.
I admire how Warren effectively incorporated geographic features of our province into Cool Water.
