Rock Carvings

A stranger named Francis Sinclair sits outside a cabin northwest of Strawberry, asking travelers to find ten old carvings scattered across these hills and mail him the coordinates. Doesn't say why he wants them, and I didn't ask. Once the tenth set's mailed, he sends an invitation to visit him at the cabin — and there's a reward waiting there worth the trouble: an old brass compass, needed to craft the Raven Claw Talisman at a fence.
