Answer: transported to this area from another region

Explanation:

The surrounding area is made of shale and siltstones so the sandstone and limestone could not have formed in that area because they have different structures.

The sandstone and limestone as well as the conglomerate cobbles must therefore have been transported to this streambed from another area where they are able to form. They probably got to this area as a result of water erosion.
