Zephyr stands at the foot of a hill, holding a large, round shield. The shield is so large that it fully obscures Zephyr's body from someone standing directly on the other side of the hill. A few moments later, Dayton reaches the top of the hill and looks down towards Zephyr's position. Can Dayton see Zephyr standing at the foot of the hill?

Respond very briefly.
Dayton, standing at the top of the hill, would be able to see Zephyr despite the shield because the top of the hill is at a higher elevation. Being above Zephyr's position gives Dayton a line of sight that isn't parallel to the ground but rather angles downwards. Thus, the shield only blocks the view for someone at the same elevation and directly on the other side of Zephyr. From Dayton's higher vantage point, the top and potentially some portion of the front of the shield would be visible, along with Zephyr holding it.
