These two tables, locations prefixes and locations, represent some that were tricky to track down.  Note that many of the maps that are included as figures in a publication often have explicitly marked locations, especially those like 120-T-24 (e.g. county-T-site). So tracking down a publication that mentions a specimen from a particular location can be a big win. The first table below lists some supporting resources for both NPL standard and publication specific location numbers.  Some sources are documented in the maps (Map OM-n) listed at the end of this page.

If you are looking for something specific, use Control+F (Command+F on a Mac) to search within this web page.

Some of the detailed data in these sources has been included in the Wiki - see the links in the notes sections below.

Counties are in Texas unless otherwise indicated.

Permian Brachiopods of West Texas, Cooper & Grant, Smithsonian Inst. Press, 1972

The publication lists numerous King localities in West Texas. Includes significant help identifying benchmarks, peaks not named on the maps, and ranches. Most of these names are old, circa 1920-40.  

West Texas Brachiopod Location Names.  Describes location naming conventions for ranches, tanks, hills, etc.

King Brachiopod Locations  includes Cooper and Grant's augmented version of King's locations with modern formation names in brackets.

Cerro de Tecolote 1Travis30.300010, -97.809700WellsHill of Owls. This is based on the well map. This was W. S. Adkins property in West Lake Hills. I believe it is one of these two hills. The well was completed in 1939. This corresponds to the map in the document showing the wells of Travis Co., so I am currently going with that. Both of these hills are rougly the right height, though I think the elevations circa 1940 were off. The well is supposed to be at 990 ft. but the tops of these hills are around 970.
Cerro de Tecolote 2Travis30.289726, -97.812651
Hill of Owls. This is Spillar Hill. This was W. S. Adkins property in West Lake Hills. I believe it is one of these two hills. It was said to have a view of the Capitol and be visible from the UT Tower. This location is closer to then-existing roads (the well was completed in 1939) and there is a community there called Spiller Hill, which is one of the Cerro de Tecolote sites. Both of these hills are roughly the right height.

Dr. J. E. Pearce leased an orchard for the U. S. Pecan Research Laboratory which was located on Little Campus at UT. The orchard was "10.5 m. NW of Austin". Found a ref to a judge being murdered by highway men on Bull Creek Rd. on his way to the experimental orchard. And Emma Long Park has Pearce Rds. around it. I believe this is City Park Rd.
