Greetings Arch is Arch Wednesday! (Issue #12) 
Worldwide arch count: 
6026 (Net Change: +126)

West Pollock Arch (Craig Shelley)

Each week we update the World Arch Database (WAD) with newly reported arches as well as more accurate data and/or photos for existing arch entries. Each Wednesday (day may vary), we send you a list of the updated arch entries with a summary of what has changed.

GNIS Project: Cross-referencing of the WAD with the United States Geological Survey's Geographic Names Information System (GNIS). The GNIS once contained many arch entries that either were not arches or did not have the right name entered, and other errors. Apparently, some folks at the USGS have been hard at work correcting this situation (with the assistance of the Natural Arch and Bridge Society). Not only have they corrected most of the errors, but they've added quite a number of arches shown on USGS topographic maps as "Natural Arch" which had never been entered into the GNIS. This cross-referencing work has yielded arch entries for Colorado, Hawaii, Illinois, Indiana, Kentucky, Michigan, Missouri and New Mexico. For some of these arches, we'll need pictures, concise GPS data, rock type and etc.

California Coast Project: Extensive research on California sea arches from border to border, in anticipation of the NABS 2013 Fall Rally on the California Coast!

New additions from GNIS system (search on a location keyword in the WAD):
Research was completed for the US states of Colorado, Florida, Hawaii, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Massachusetts, Michigan, Minnesota, Missouri, Montana, Nevada and New Mexico. All arch names are official GNIS names unless otherwise noted.
Colorado: Window Rock and Picture Window (Las Animas County); Rhoda's Arch (Mineral Co.); Outlaw Arch (a huge arch in Dinosaur Natl Monument) and Escarpment Arch (Moffat Co.).
Hawaii: Onomea Arch on the E side of the Big Island (Hawaii Co.); Keaulepe, on the N side of island of Niihau (Kauai Co.); The Arch on the island of Kahoolawe (Maui Co.).
Illinois: Cedar Wonders Arch (Johnson Co.).

Indiana: Ravine Arch (Crawford Co.).
Kentucky: Burnt Bridge (Rockcastle Co.).
Michigan: Amygdaloid Arch, Isle Royal NP (Keweenaw Co.).
Missouri: Ash Cave Arch (Barry Co.); Roche Percee Arch (Boone Co.); Lost Hill and Dry Sac Arches (Greene Co.); Anvil Rock Arch (Osage Co.); St. James Bridge and Pinnacle Arch (Phelps Co.); Duchien Cave Bridge (Pike Co.); Pickle Springs Arches (Ste. Genevieve Co.).
New Mexico: Phoenix Arch (Los Alamos Co.); Cat's Eye and Window Rock (Rio Arriba Co.); Cutter Lake, Gobernador Cyn and Pemada Cyn Arches (San Juan Co.) - these were previously known via arch hunter Larry Beck.

Changes to WAD entries from GNIS research:
Mesa County, Colorado: Official name of West Rim Arch in Rattlesnake Cyn is Finger Arch; official name of Mesa Arch in Pollock Cyn is West Pollock Arch.
Randolph Co., Illinois: Coordinates for Cow Shank Bridge.
Douglas Co., Missouri: Official name of Lakey Bridge is Sweden Fork Bridge.
Phelps Co., Missouri: Official name of Vreeland's 14-27 is Kaintuck Hollow Bridge.

Errors found in GNIS data: None
However, there are two arches in McCreary County, Kentucky which have names in extremely common use which are not shown in the GNIS. "Natural Arch," entry No. 514196 should be "Natural Arch of Kentucky." "Natural Bridge," entry No. 514199 should be "Wagon Bridge."

California Coast Project:
Research has begun using sources other than the USGS-GNIS. We have dozens of new entries from the Natural Arch and Bridge Society's GIS Catalog, as well as dozens more from the Journal of Natural Arch Discoveries. We're also cross-referencing these sources between themselves and with all SPAN articles on California arches. We've done a lot of upgrading to existing entries with coordinates, photographic potential ratings, better directions and more. Thanks to Ted Dahlmann, Nicholus Terzakis, Jay Wilbur and others for providing most of the data over the years. Looks like Mendocino County is in the lead so far, with 77 arches! (Marin Co. is a distant second with 33).

Happy Arch Hunting!
yours truly,
Stone Canyon
