This is after creating a mosaic with check_exists

It turns out that this is because not all historical topo maps are 7.5'x7.5'.

In this particular case, this is a 7.5'x15' map.

So it wasn't coming up on the metadata search because I was including 7.5'x7.5' as part of the query.

The best way around this might be to use the bulk metadata export: https://s3.console.aws.amazon.com/s3/buckets/prd-tnm/StagedProducts/Maps/Metadata/?region=us-west-2&tab=overview

Fixed by opening up to arbitrary map scales, and no longer constricted to 7.5'x7.5' quads.
