Cathedral Gorge Moonlight Erosion – Nevada Tucked away in the south east corner of Nevada, this gem of a state park offers geologic wonders that any landscape photographer would love. The park offers an interesting geologic mix, from ash and pumice deposits, to the sediment of an ancient lake that are slowly eroding away in the dry desert climate that now exists. If you have ever seen photographs of the place, the size of what you see can be very deceiving in photographs. Everything looks much larger than it really is. But don’t let this deter you from visiting. You’ll have numerous opportunities to explore the different erosion features, from cave like passageways carved out of the ash deposits, to ruggedly sculptured rock faces, and stone pillars.
