There have been several instances in the last 150 years when valuablematerials such as diamonds have been found contained in glacial debris. ifone wanted to try to trace such valuable materials back to their source, whichmoraine would be most useful for tracing valuable gold deposits back to theirbedrock source area? a. recessional moraineb. terminal morainec. lateral morained. esker

The most useful for tracing valuable gold deposits back to their bedrock source area is the

Lateral moraine

Explanation:

Lateral moraines are sharp created piles of glacially transported rocks and debris that are dropped by the ice as it melts. This makes them good indicators of where the line between the accumulation zone and the ablation zone. They often remain on the landscape long after glacier retreat making them a valuable site for gold deposit.
