This is Black Butte. Again, the soil is volcanic, which means that it is rich. This area gets just enough moisture to allow thick, tall grass to grow. The horses in the field behind the woman are clearly pleased with the thick, rich grass.
The water is also close to the surface in spots right here. Notice the willow bushes growing to the right of and behind the woman. Where willows grow, water is within 20 feet of the surface.
