Northern California landscape. We live in the Tri-Valley. There are mountains surrounding the valley. Low mountains. Mount Diablo (pictured here) is the highest mountain at 3,848 ft. Low clouds hang on the mountains in the winter. Fog is more typical other parts of the year. The photo also shows the oaks and grass land (oak savanna) typical of this area. The rolling hills below Mount Diablo are turning green with the winter rain. And of course houses jammed in everywhere possible.
