Here is the official map of the Committee's deliberation.
Since parts are hard to read, I will list important map text going clockwise from the upper right corner:
"Navajo Bridge": The Park boundary is at the mouth of the Paria River, though the text refers to the bridge a few miles downstream.
[One way to think about some of these notations is that they were more relevant in an earlier part of the legislative history.]
"MARBLE CANYON EAST Proposed Boundary on Canyon Rim Note: Subject to Concurrence of the Navajo Nation" : Goldwater & NPS wanted a rim boundary, but the Navajo would not agree (and still do not), so this notation wistfully suggests it is "proposed", a dream. One might ask then, if the rim is "proposed", where is the "real" eastern boundary?
"COCONINO PLATEAU": Just above the text are the 3 partial sections moved from the Forest to the Park.
The two existing parts of the Havasupai Reservation were labelled. Cross-hatching shows the Use Area; diagonals the Reservation addition.
"BOUNDARY: approx ¼ mile back from canyon rim." This refers to the Havasupai Reservation addition's northern boundary; additional information on crossing Havasu Creek was in the body of the bill.
"164.8 RIVER MILE" AND "273.1 RIVER MILE" identify the points on the Park boundary described as "Boundary on South Bank of Colorado River (River Mile 164.8 to 273.1)"
"Boundary on Canyon Rim" appears twice on the north side to show that the Park was only to include canyon, not any rim land in the Kanab, Whitmore, Parashant-Andrus additiions.
"MARBLE CANYON WEST Boundary on Canyon Rim": No proposed or concurrences here; the land was all federal to begin with, and the boundary was emphatically on the rim.
[Given the many uncertainties, I now believe that this attempt to use such a rough-scaled map has led to many of the difficulties described in the myriad posts I have made in this blog about the individual boundary segments.]
This official map drawn by the Park Service to show the House Interior Committee's decisions was legislative change at a peak: Those advocating additions to the Park received their reward, 230,000 acres more for a total of approx. 1,406,500 acres, and the entire river from the Paria to the Grand Wash Cliffs under the one, Park, administration. The Havasupai had their two-piece recognition: repatriation of approx.185,000 acres and mandated traditional use for approx. 95,300 acres more. Surely this was a feast for both hungry contestants.
And with a complete study for Wilderness, nothing but empty words for the dam builders, a chance to study the curse of noise from over-flying intrusive aircraft, topped by congressional recognition of the complete wide-spread fling of the Canyon, what a triumph, what a victory!! Park advocates had a highly nutritious package of legislative sausage to push hard to get through the House and a final vote as quickly as possible.
But no; for all the beauty of the forest, attention became transfixed on trying to thin out individual trees some considered obnoxious. That battle was next fought after the Committee for 2½ months to votes of the full House, and then for a similar period in the shadows of the conference held to reconcile House and Senate versions.
But still, for a moment, contemplate that glimpsed peak.
