Monkey Rock is located just east of Ken's Lake Recreation Area. The lake and picturesque landscape are a short drive south of Moab, Utah. On this evening in September, the opportunity for clear sky and a quarter moon made for a great twilight image. I took full advantage of the ambient light to achieve the image stack. The quarter moon's light, along with the twilight color in the sky during the "Blue Hour", just before Astronomical Twilight, enhances the landscape.
