Greetings Arch Hunters...today is Arch Wednesday! (Issue #25) 
Worldwide arch count: 
6102; Net Change: +4; Fallen: 25

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.

Natural Bridges National Monument/White Canyon Project (Utah, USA) 
We are continuing to enter and update arch data in these areas in anticipation of the Natural Arch and Bridge Society's (NABS) Spring 2013 Arch Rally. Search US>UT>San Juan>location keywords "Natural Bridges" or "White Cyn."
Red Bar Arch: New entry. Quite a nice arch! Reported by Peter Jamieson and Gwenda Ferris. Search for this one by its name.
Butler Ruin Bridge: We changed the name of this arch from Butler Wash Arch to Butler Ruin Bridge because it was found to be a Waterfall Bridge (was formerly listed as a Pothole arch). We also entered coordinates for this arch. Search for this one by its name.
White Canyon Arch: We now have coordinates and better directions to this arch.
Kachina Bridge: New measurement of span by Jay Wilbur and Craig Shelley of 192 feet (shorter than previously thought).
Sipapu Bridge: New measurement of span by Jay Wilbur and Craig Shelley of 225 feet (shorter than previously thought, but still in the top 10 longest spans in the world - see LAIP Project below).

Largest Arches Inventory Project (LAIP): Focusing on updates for the largest arches in the world, defined in the World Arch Database as arches having a superior Greater Arch Dimension (or GAD), this project will be ongoing over the next several months.
This week's new entries for the LAIP are Gaotun Bridge (data provided by Gunter Welz and Ray Millar) and Jiangzhou Bridge (data and photo provided by Ray Millar), two of the longest spans on planet Earth (in China), and a large arch in Afghanistan called Hazarchishma Bridge, all with spans of over 200 feet! If you're a member of the Natural Arch and Bridge Society (NABS), you probably already know about these fabulous natural bridges because they were featured in NABS' quarterly publication, SPAN.
LAIP Updates:
We now have more accurate measurements of several more of the largest arches in the world courtesy of NABS. We also have better directions to these arches and other data that has been updated (such as the arch type).
Kolob Arch, Utah; Morning Glory Arch, Utah (not a bridge); Shipton's Arch, China (new photo by Ray Millar); Outlaw Arch, Colorado (new photo by Scott Patterson); Stevens Arch, Utah; and Rainbow Bridge, Utah.

We have other ongoing projects
, including the California Coast Project which we'll be updating in the coming weeks.


Happy Arch Hunting!
yours truly,
Stone Canyon
