These were taken back in April of this year at Wichita Mountains Wildlife Refuge after it had received a substantial amount of rain. On the top photo, the dam was blocked when we got there to take pictures. Ron and I unblocked it to be able to get the pictures we were wanting. I had to climb down a very steep rock face to get below the dam. On the bottom two photos I used every ND filter I have, but even with those I was only able to get a half second shutter speed. These were shot mid day and the sun was very bright.
