River of Stones - July Challenge

Fiona Robyn has proposed a challenge for bloggers to notice (and appreciate) one small thing every day in July. See her Facebook page here.  I doubt that I will have time to post something every day in July, but here are my first two:

July 1 - The surface of the river in an unusually still afternoon, like mercury under the silver sky.

July 2 - The glimpse of a dolphin fin in the blue-pink ocean at sunrise. There! Then gone.
