Cottonmouth Crossing Tour Road
I spotted this Cottonmouth on the Sequoyah National Wildlife tour road (Oklahoma). Sometimes these snakes will come up on a road to sun. I believe this one was crossing from a slough to Sally Jones Lake. I see lots of Cottonmouths in this area.
On bright, sunny days, they are usually found coiled or stretched out somewhere in the shade. In the morning and on cool days, they can often be seen basking in the sunlight. They often emerge at sunset to warm themselves on warm ground (i.e., sidewalks, roads) and then become very active throughout the night, when they are usually found swimming or crawling.

The Cottonmouth is not limited to aquatic habitats. I have come across these snakes while hiking in the Ouachita National Forest here in Arkansas. I read that they can move more than a mile from water.
How I Got The Shot - Cottonmouth (Water Moccasin)
I drove up on this snake at the Sally Jones West Causeway (Sequoyah National Wildlife Refuge). I parked and exited my pickup with my camera.
I was hand holding my Canon EOS 7D Mark II with the Canon EF 100 - 400 mm f/4.5-5.6L IS II lens. I was shooting in aperture priority mode (AV) with a shutter speed of 1/2500 of a second at f7.1 and the ISO at 400. White Balance was set on auto. I was using single point, continuous auto focus with evaluative metering.
