Rowena pond creates a summertime oasis as it retains water through the arid summer. The dry plateau on Rowena Crest is east of the Cascade Mountain ridgeline and approachs the high plains desert. In the summer, the ground is dry and the grass is parched except near depressions in the basalt where water collected in the winter and lasts trhough the summer. Small circular wetlands survive the summer as oases for wildlife. In this cloudy afternoon October image, the oaks are changing colors.
