It really should be the impetus of the USGS to mine the OSM for GNIS
updates. Don't sweat it.

This is very common. It happens at the edges of the 7.5' quad sheets.
A feature would be indicated on both sheets but not in exactly the
same location. It makes sense when you see the sheets as separate maps
- but combined it just looks screwy.

Generally they are both "correctly" positioned because they are point
features representing something that's actually a polygon. It makes
perfect sense to just keep the first one encountered and throw out the
others in a batch import. Then let crowd-sourcing take over!
