It seems possible that way/157329997 and way/625187013 could be merged with the tags transferred.

Since this is a geological feature, aerial imagery might not give us a good representation of the extent of the feature. (Some parts may not be apparent in the imagery, or might be obscured e.g. by sand.)

If I were trying to merge the ways, I would try to confirm the extent of the feature from one or more reliable external sources to decide which of the two ways more correctly defines the boundary of the feature.
