Greetings Arch Hunters...today is Arch Wednesday! (Issue #10)
Worldwide arch count: 5868 (Change: +7)
Each week we update the World Arch Database (WAD) with newly reported arches as well as more acccurate data and/or photos for existing arch entries. Each
Wednesday (day may vary), we send you a list of these updated arch
entries with a summary of what has changed. Typically our weekly updates
will focus on a certain area, state or country (although we may jump
around the world at times!).
This week we are continuing with our new project: Cross-reference 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 have added quite a
number of arches which were shown on USGS topographic maps as "Natural
Arch" that had never been entered into the GNIS. This cross-referencing
work has yielded 21 previously undocumented arches in Arizona alone!
We'll need pictures of these arches, as well as concise GPS data, rock
type and etc. GO GET 'EM ARCH HUNTERS!
We are also updating all arch data for the White Canyon area of Utah,
USA, including Natural Bridges NM, in anticipation of the NABS Spring
2013 Arch Rally.
New additions from GNIS system (search on a location keyword in the WAD):
Research was completed for the US state of Utah. All arch names are official GNIS names unless otherwise noted.
Breeze Arch: In Weber County, Utah E of Ogden and near Snow Basin.
Bell Tower Window: On E side of Lake Powell, UT on rim of a small side cyn of Glen Cyn, N of Ribbon Cyn (Alan Silverstein report to USGS).
New additions from UtahArches.com: Five arches in and near Arch Cyn, San Juan County, UT, USA.
Changes to WAD entries from GNIS research:
Diamond Fork Arch, UT: better coordinates and directions
Jeep Arch near Moab, UT: official name is Gold Bar Arch
Chinaman's Arch Box Elder County, UT: official name is now Chinese Arch (this arch may have fallen)
Private Arch in Arches NP, UT: official name is now Oval Canyon Bridge (this needs to be confirmed on the ground using modern GPS)
Parade of Elephants in Arches NP, UT: official name is Elephant Arch
Horse Collar Ruin Arch Natural Bridges NM, UT: Official name is actually Indian Foot (see below - errors in GNIS data).
Arch UT-126 Natural Bridges NM: This arch was mis-labeled as Indian Foot (see below - errors in GNIS data).
Other Changes: Arch UT-665
in White Cyn, UT was named Ducket Arch for a nearby canyon
crossing of White Cyn of the same name (UtahArches.com).
Errors found in GNIS data
Natural Bridge in Canyonlands NP, UT on Cathedral Butte Quad, GNIS entry no. 1448725. There is no arch at the coordinates given.
Nequoia Arch Emery County, UT,
GNIS entry no. 1451309. This is not an arch as defined by either
the USGS or NABS. It is indeed an arch, but it is an underground feature
defined by the scientific discipline of geology, and which has the
potential to trap hydrocarbon deposits.
Horsehoof Arch: fallen and should be shown as "historical."
Gregory Natural Bridge: shown as
"historical" but should not be since it is still standing and most of
the arch has been above water as recently as 2004.
Arrowhead Arch, Yellowjacket Cyn, UT near Moab: fallen and should be shown as "historical."
Cave Arch, UT: We believe this arch has fallen and should be shown as "historical."
Hole-in-the-Rock, S of Moab, UT: This is a man-made hole in the rock housing a convenience store, not an arch.
Indian Foot, Natural Bridges NM,
UT: The GNIS system has the wrong coordinates for this arch. The
coordinates are actually for another arch (arch UT-126). There is an
arch on the S rim of White Cyn between Kachina and Sipapu Bridges that
is commonly known as Horse Collar Ruin Arch, but is actually the real
Indian Foot. This is quite evident when looking at photos of this arch
from below - looks just like a human foot, while arch UT-126 does not in
any way resemble a human foot.

Happy Arch Hunting!
