East of the Cascade Mountains, Washington’s climate is arid and the terrain is desert-like. Summertime temperatures can exceed 100 degrees Fahrenheit in regions such as the Yakima Valley and the Columbia River Plateau. This is an area of rolling hills and flatlands. During the last Ice Age, 18,000 to 13,000 years ago, floods flowed across this land, causing massive erosion and leaving carved basalt canyons, waterfalls and coulees known as the Channeled Scablands. The Quincy Lakes area is part of the scablands of central Washington State. Visitors to this area will experience basalt cliffs, mesas, benches, canyons and potholes. Several of the potholes have become lakes that are filled with water seeping from the irrigation of nearby upslope farmlands. Ancient and Dusty lakes are two examples that have added to fish and wildlife diversity and have also become important recreational areas. Ancient Lake and Dusty Lake are in the Quincy Wildlife Recreation Area near Quincy, Washington State, USA.
