Julius Gorton pushes a rectangle-shaped rock into the ground then shakes it. Still loose. He takes the pick axe next to him and hammers it down.
“OK, maybe it just needs to dig out a little bit,” Ella Marshall says. She moves the rock aside and starts digging a gap into the dirt, her hands protected by purple gardening gloves. They wedge the rock back in and hammer it down a few times. Satisfied, they start adding more rocks around it.
