Yep, its late, but I had to get this list to the chief cartographer by today in order to get a geodatabase set up as soon as possible. Take a look and provide any comments if any come to mind. The list is somewhat stream of consciousness and may be missing a critical unit or may not reflect your conceptions. Let's work toward a consensus if needed.

  1. Kyle, this looks pretty comprehensive. The only thing that struck me as missing was perhaps the Greely lavas. Don't we think they are a legitimate separate unit, or are they going to get thrown into "undifferentiated"? Also, just to double check, we don't think the AM/PM lavas are a separate unit, right? They are probably some combination of West Crater and maybe Clark's Butte?

  2. You are correct. That unit is missing. Thanks! Look for more.
