About this map

Trinidad and Crescent Bar sit along the eastern banks of Wanapum Lake, where the landscape drops sharply from the volcanic plateaus of Central Washington. The terrain is defined by dramatic geological formations like Babcock Ridge and Babcock Bench, carved by ancient floods that left behind Potholes Coulee and Crater Coulee. This 2023 survey illustrates the complex water management system of the region, featuring the West Canal and several smaller bodies of water such as Ancient Lake, Cliff Lake, and the Evergreen Reservoir.

Modern infrastructure and recreation are prominent, centered around the developments at Crescent Bar and the Quincy Flying Service airfield near the northern boundary. The map tracks the steep elevation changes along Lynch Coulee and Baird Springs RD NW, providing a detailed view of the transition from the high-desert ridge down to the Columbia River basin. This recent data allows for the tracing of established roads and the numerous small lakes, including Dust Lake and Crystal Lake, that populate the floor of the coulees.
