Were you near the Woolsey fire? If so, that could be Phos-Chek that had been dropped as a fire retardant. The rain would have rinsed it off the foliage in your garden.
If it is indeed Phos-Chek, relax. As it breaks down, it becomes fertilizer.

A Redditor says it might be rust since it matches since the orange is like dust. Also digging under it revealed regular dark brown soil like you see around spot.
