Lake Umatilla dominates the center of this landscape, marking the state boundary between Washington and Oregon. Along the northern shore, the settlement of Paterson sits at the foot of Paterson Ridge, supported by local infrastructure including the Columbia Crest Winery Airport and Columbia Crst. The river environment is defined by a complex of islands and wetlands, such as Monument Island, Big Blalock Island, and the winding McCormack Slough. To the south, the city of Irrigon serves as a hub for the local road network, including Paterson Ferry Rd and Riverview Ln. This map captures a modern intersection of historical routes and contemporary agriculture, specifically noted by the Morrow Co Heritage Trail and the Umatilla Heritage Spur Trail which trace the land south of the water. The presence of the Irrigon Lower Range suggests the importance of river navigation and shoreline management in this reach of the Columbia River basin.
