Adam Peak 7.5 Quad (1:17,000 to 1:62,500)
The As-Published version of this map is from Hotz and Willden's 1964 15' quad map. The Enhanced version of this quad is from four separate sources. The center spine of the range, and the SW corner of the quad are from Hotz and Willden's 15' quad map. The west side of the range is from Liz Jones-Crafford's dissertation, the east flank of the range is from R. Boskie's compilation in a GSN guidebook and thesis, and the covered areas are from new photogeology.

Anderson Gardens 7.5 Quad (1:62,500)

Antler Peak 7.5 Quad
The As-Published version of this map is from J. Doebrich's 1995 7.5' quad map. On the Enhanced version, most of the quad is from J. Doebrich's quad map. The area of the Buffalo Valley Moly prospect is from T. Thomas' Thesis. Covered areas are slightly re-interpreted from new photogeology. A great deal of mining, grade, and geology data has been added.

Artesia Lake 7.5 Quad
The As-Published version of this map is from Stewart and Dohrenwend's 1984 15' quad map. The enhanced version bedrock geology is mostly from Proffett and Dilles' 1984 map, Hudson and Oriel's 1979 map, Dilles' 1987 map, Einaudi's 2000 map and Stewart and Dohrewend's 1984 map, with updates in the Buckskin range area from the small-scale map of Dilles and Wright (1988). Some formation names were updated based on Proffett and Dilles (2008). The alteration is from Dilles and Einaudi (1992), Einaudi, (2000) and Halley and others (2015). All these sources suffered from poor quality (or non-existent) base maps, and I have adjusted nearly every fault and contact trace to match NAIP 2017 orthophotos. I have also completely re-interpreted all the cover rocks and made a few field checks in various small areas.

Bingler's 1978 map covers the entire quadrangle and is availiable as an as-published 15' quad. Surpless' 2010 map also covers the entire quadrangle but has not been split out as an "as published" map. The enhanced bedrock geology is from Surpless' 2010 map, McIntyre's 1990 map and Binglers 1978 map,. Some formation names were updated based on Proffett and Dilles (2008). Alteration is from Surpless (2010), Bingler (1978) and photogeologic color anomalies. Bingler and Surpless' geology suffered from poor quality base maps, and I have adjusted nearly every fault and contact trace to match NAIP 2017 orthophotos.

I also made extensive field checks in the bedrock areas. Some formation names were updated based on Proffett and Dilles (2008). The alteration is mostly photogeologic color anomalies. Most of these sources suffered from poor quality base maps, and I have adjusted many fault and contact traces to match NAIP 2017 orthophotos.

I mostly corrected this for thrust faults and folds based on the accompanying text, but the status of most high-angle faults in and bordering alluvium is equivocal and will have to wait for a much more in-depth study.
