About this map

The John Day Fossil Beds National Monument occupies a significant portion of this landscape, protecting world-renowned paleontological sites along the western margin. This 1990 provisional map records the intersection of geological history and ranching life, centered on the John Day River as it winds past the Mascall Ranch. The drainage patterns of Johnny Cr, Dick Creek, and Franks Creek carve through high plateaus like Sunflower Flat and Timber Basin, creating a complex network of canyons and gulches.

Evidence of local industry and infrastructure appears in the form of the Erickson Mill and the Lands End Landing Strip, highlighting how isolated reaches of Grant County were navigated and utilized. Distinctive topographical curiosities such as Hole In The Ground and landmarks like Sugarloaf and Windy Point provide specific reference points for researchers and genealogists tracing family ties to these high-desert ranchlands.
