Comments:

1. One of the units was listed in the original table, and in the descriptions PDF as "Estruarine deposits". I believe this was a typo, but I was not certain. I changed this name to "Estuarine deposits".
2. There were geology shape files for the entire region and for Dillingham Quadrangle separately. I included both. The zip file for Dillingham is titled dillgeologydump. the zip file for the entire region is called geologydump.
3. There is a third zip file for the folds shape file titled foldsdump.

Is this significantly better than the new Alaska map that we recently imported? That map was made by aggregating things like this.

Many of the descriptions are quite a bit longer than the new Alaska map. A few of them are nearly exactly the same as the descriptions from the new source and the detail of the polygons looks to be about the same. I think there is also a more thorough breakdown of units. For example in this source the Naknek Formation is described on it's own and two of its members are also described individually. It looks like the Alaska map imported right now only described the Naknek Formation and Kotsina Conglomerate together from what I can see.

It looks like there is more overlap than I thought. The unit names are definitely much more classified than in the Alaska map already imported.
