In support of regional geologic framework studies, we obtained 50 new argon/argon (40Ar/39Ar) ages and 33 new uranium-lead (U-Pb) ages from igneous rocks of southwestern Alaska. Most of the samples are from the Sleetmute and Taylor Mountains quadrangles; smaller collections or individual samples are from the Bethel, Candle, Dillingham. Reported ages of the stock range from to Ma (K-Ar, biotite; Schwartz, ; McDowell, ), but unpublished 40Ar/39Ar data by NMBGMR indicates the age of the stock is slightly younger, at Ma (Table 2).

Conejos lavas in the vicinity of the Platoro Caldera complex have been subdivided into the Horseshoe Mountain, Rock Creek, and Willow Mountain members, based on differences in composition and phenocryst mineralogy (Colucci et al. ). Potassium-argon and 40Ar/39Ar ages indicate activity from before 33 Ma to about Ma.
This paper presents new field data on the volcanic rocks of the Western Cordillera, new paleomagnetic constraints, and a new stratigraphic framework for oceanic plateau postcollisional volcanic rocks based on an extensive set of new U-Pb and 40ArAr geochronologic ages.

In hindsight, a comparison of the older Dry Cave sites with two major sites west of the Guadalupe Mountains under the intent to compare Mid-Wisconsin climates (Harris ) may have been comparing sites of two different ages, and some of the differences .1.
