It was another long February day, planting trees near the East Fork Lewis River in rural Clark County, Washington. Snowflakes fell on the freshly turned soil but didn’t stick around. Just before my digging tool thudded into the soggy earth, I saw a leaf move. A green leaf on the ground, at this time of year? I crouched for a closer look and spotted a little chorus frog hiding under the moss, though it stood so still it took me a minute to make out the shape. As I pulled out the camera and took pictures from various angles it didn’t move a muscle.
