We had another Soft Shell Turtle lay her eggs in our front yard. I watched her laboriously dig her nest. It’s surprising how high and how far she could fling the sand while digging her nest. You couldn’t even tell where the nest was once she finished laying and covering the nest.
My settings were ISO 400, f/6.3, 1/2000 sec, at 300mm (70-300mm). Did some cropping.
