Greetings Arch Hunters...today is Arch Wednesday! (Issue #12)
Worldwide arch count: 6026 (Net Change: +126)
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.
GO GET 'EM ARCH HUNTERS!
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
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
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.).
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
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
Happy Arch Hunting!
