McGregor Ranch and the nearby Mc Gregor Airport anchor this high-plateau landscape in Whitman County, characterized by a series of deep canyons and seasonal water sources. The map details the complex drainage systems of Hooper Canyon and Woods Gulch as they cut through the dry terrain toward Alkali Flat Cr. Historically significant water points for ranching and travel are clearly marked, including Mays Spring, Goldfish Spring, and Adarrio Spring. To the northwest, a cluster of small basins contains McGregor Lakes, Clear Lake, and Hooper Lake, providing a distinct contrast to the surrounding flats. The rural infrastructure of the early 21st century is reflected in the network of local roads such as Rock Springs Rd and Thomas Flat Rd, which connect isolated agricultural holdings like the Gordon Farm.
