2011 Map of Big Rock Flat

About this map

Parkers Mill and Reeds Mill stand as markers of historical industry within this high-elevation landscape of Morrow County. The area is defined by a series of flats and ridges, most notably Big Rock Flat, Little Rock Flat, and Sunflower Flat. Water sources are critical in this terrain, with numerous springs such as One Trough Spring, Opal Spring, and Morphine Spring feeding into drainages like Rock Creek and Hollywood Creek. The network of forest roads, including Kinzua Rd and Toll Rock Rd, suggests a landscape shaped by both timber management and historic transit. To the south, Rough Canyon Reservoir provides a significant water catchment point near Morphine Canyon and Morphine Ridge, highlighting the topographical complexity of the region's volcanic and erosional features.
