In the lingering summer heat, I visited the forest on the beginning. The forest was first one visited for this observation five years ago.

“Crabs in holes on the beach”

Summer beach in the Chita peninsula. There were many holes in the sand. Numerous balls of sand around the hole. I decided to move away from the hole and see what happened.
