As of Sep 2010, GCNP Boundary: Summary, including questions (added to, 9/24)

This entry will list each boundary segment by letter, name, boundary sharer, and entry date(s) -- all in 2010 --; then summarize any relevant comments, and in particular, describe any open questions, ambiguities I found, possible disputes, and a brief comment if the boundary might be changed to bring about a more complete GCNP. I use abbreviations for two comments I find apply to several items:
Natural-Line Ambiguity Ameliorated By Friendly Sharers(NLAABFS);
Needs Congressional Correction (NCC)

Introductory entries were made July 12-14. Here are the official map and the segment index map, which better shows the boundary sharers.

A Start and The Colorado River Navajo, Hualapai   Jul 16
  Congress placed the entire water surface from the Paria to the Grand Wash Cliffs in the Park; some bureaucrats, lawyers, and others want to ignore the law.
  Also, the point is introduced here, in connection with the Paria junction, that placing boundaries on natural features, whether in words or on maps, inevitably leads to varying ambiguity on the ground. This is countered by the sharers being friendly  and cooperative; thus obviating the need for fencing, should that even be possible. This is the doctrine of natural-line ambiguity ameliorated by friendly sharers(NLAABFS), which applies with greater or less force on almost every segment.

B Marble Canyon east         Navajo                     Jul 18-23
  My definite view is that the Park boundary comes to the left bank, that the Navajo boundary comes down to the water's edge, and the wet-foot/dry-foot doctrine applies. The U. S. gov't (NPS) never demonstrated the amount of national interest necessary to justify use of the qualifying clause in the 1934 Navajo boundary Act.

C Ancient relic Navajo       Jul 24
  A matter of historically based amusement, that shifting from latitude/longitude to legal section lines (from unsurveyed to surveyed) may have scraped some Park into Navajo land. No matter, the boundary is now well defined.

D NPS Village and rim Kaibab NF         Sep 1, 10
  Is it acceptable that a 320-acre error by map drafters becomes the law? Apparently.
  One assumes that the NPS and FS were partners in setting the line that was only defined with reference to a road survey, and that there is no disagreement. 

E Havasupai Havasupai         Sep 5
 All quiet on this front, in spite of NLAABFS, and oddities in some of the line descriptions.

F Hualapai Hualapai         Sep 6
 Congress put the river surface, to the south bank, in the Park. The Hualapai have claimed to the river centerline; NPS to a highwater line. Both are wrong, as I will argue fully in a later entry.

G West end, the wattle Hual,BLM,LMNRA       Sep 9
 An unthought-through addition, I blush to say, that needs congressional correction (NCC). There is NLAABFS along the fluctuating shoreline of Lake Mead, where the wet-foot/dry-foot doctrine rules. For the time being, G is being correctly defined on maps.

H,I West end & Shivwits LMNRA, BLM         Sep 9
 As with G, H was carelessly defined, NCC, has NLAABFS, and is as correctly drawn as matters.

I Shivwits LMNRA, BLM         Sep 12
 Clear enough in principle, but resulting in mapping differences over odd details, though probably made irrelevant by NLAABFS. 
NCC to include plateau top.

J Andrus-Parashant, Whitmore LMNRA         Sep 13
 In spite of its weird history, the line is well-defined by the "Boundary on Canyon Rim" notation on the Act map after dropping from the Shivwits rim. The canyon rims are fairly obvious, and NLAABFS. Incorrect maps do exist, however, as traps for the unwary.  
NCC to fill out Esplanade and incised canyons.

K GCNMonument #2 LMNRA, BLM, KNF      Sep 16
 The boundary has been contested but stable for 70 years, except for the Coconino Plateau going to the Havasupai. It is now a combination of section lines and NLAABFS. Does upper Toroweap Valley NCC?

L, M Kanab Canyon, Rim Kaibab NF         Sep 17, 19
 Primarily there is NLAABFS with the usual discrepancies in details between different maps. The Act map's notation "Boundary on Canyon Rim" is more puzzling than useful here. 
The argument, however, would not usefully be over different interpretations of the map lines, but how to add the rest of Kanab to the Park, NCC

N Kaibab Plateau Forest KNF         Sep 20
 A long-settled matter; partially NLAABFS.

O P Marble Canyon west KNF, BLM, Glen NRA   Sep 20
 Boundary on the rim including side canyons as shown on Act map;  NLAABFS.
