Suspicious Gravel in Abandoned Campsites

Since these structures have gravel, it feels like a missed opportunity not to include archeology. It makes sense that if those who lived here left loot in the chests, they would have left items in the ground too. Campsites already have the perfect spots for archaeology with little holes in the ground packed with gravel and the patches of gravel scattered around the campfires.

Since these structures are abundant and oriented towards the early game this would be a great way to introduce new people to the feature. The chests and barrels found in campsites should also include brushes.
