This spot is about 18 miles south of Missoula, MT on Rt. 93. Turn left at the traffic light in Florence, and within about 1 mile, there is a turn-off on the right (just before the river) where one can pull in, park, and see the area up close. This is used primarily for lots of fishermen.
I took this photo right after a storm had started to clear on a fall morning. I attached an Infrared filter, and used a Really Right Stuff tripod to accomodate the 8 second exposure. This shot is looking South down the Bitterroot River.
