Gorge Creek Falls sits in the Ross Lake National Recreation Area of North Cascades National Park. The main vantage point of these falls are a metal bridge that sways and shudders when traffic goes over it – and it doesn’t have the sort of surface you could put a tripod on. I have found this spot to not be very hospitable to photography, though the views are excellent. I had a bit better luck earlier this year while trying a vertical “panorama”.
The first photo here is of the Gorge Dam just outside of Newhalem, Wa.
