Sanhedrin Wilderness
The "Sanhedrin" was the supreme council of the ancient Hebrews. The pioneers who gazed up at this rugged ridge must have been very impressed indeed to have given it such a dignified Biblical name. But Sanhedrin Mountain is more than just one of the most imposing peaks in Mendocino County. The mountain's ancient forests are so pristine that they provide critical habitat for the continued survival of the northern spotted owl. The area also contains extensive meadows, oak woodlands, chaparral, and "serpentine barrens," places where the nutrient poor blue-green soil is so inhospitable to many plants that only specially adapted species can survive.
