Comments in response to Inventory and Evaluation Process draft document dated July 21, 2015, obtained at the public information meeting in Magdalena on August 4, and the Phase 2 Inventory maps for the Magdalena Ranger District. These comments concern the inventory for the Magdalena Mountains, as summarized in the above documents. Area D3_5K2: This area has been excluded from the Phase 2 inventory due to being reduced from its original size of 5,166 acres to 4,742 acres and considered to be of insufficient size to be managed in an unimpaired condition. In addition it is stated that it is not contiguous to the Langmuir Research Site. According to the Phase 1 map available at http://www.fs.usda.gov/Internet /FSE_DOCUMENTS/stelprd3816212.pdf, and the more detailed Phase 2 maps, the area is clearly adjacent to the Langmuir Research Site along its NW border. I am personally familiar with the Langmuir Research Site and with the inventory area in question. The common border between the two is at high altitude and rugged terrain immediately below South Baldy peak and the Magdalena ridge extending both north and south from the peak. Most of the land in the inventoried area is very rugged and/or undeveloped, and would be easily managed to retain its unimpaired state. It has survived as such for over 50 years that I have lived in Socorro and worked at Langmuir, without benefit of special management. In addition, the area borders on its northern boundary with area D3_5K1 in the north-central part of the Magdalenas, which remains on the Phase 2 inventory list. The dividing line between the two is Mill Canyon, which is not a major impediment to considering the two areas for Wilderness designation. The narrow canyon houses the historic Frenchie Cabin and provides access to a relatively small, similarly historic but largely unproductive gold mine on the Magdalena Ridge area. Neither of these features detract significantly from the wildness of the area. From my personal experience of hiking in the area they do not detract from the opportunities for solitude, nor from the spectacular vistas looking westward from the Magdalenas over the San Augustin Plains area and the San Mateos to the southwest. If a Wilderness Area is recommended and established in the Magdalenas, which I would strongly advocate, it needs to include the full extent of the Magdalena ridge extending northward from the South Baldy to the North Baldy area, including the west side of the ridge area constituting the D3_5K2 area in question. The Wildnerness area should be a geographic entity that extends well westward from the ridge both to the north and south of Mill Canyon. For these and the above reasons concerning the naturalness of the overall area, 5K2 should be reinstated the Phase 2 inventory. Area D3_5K1: This area has remained largely intact through the Phase 2 analysis and, combined with the similarly intact 5K3 area and area 5K2, is well qualified for Wilderness designation. My main comment concerning 5K1 is that the area immediately north of FR 39 in North Fork canyon needs to be added to the inventoried area, so as to not preclude it from being considered for a future Magdalena Wilderness. FR 39 should be cherry-stemmed out along its lower part and the remainder being included in the inventoried area, in the same manner that route 505B has been treated in the northern part of 5K1. As currently inventoried, the area in question is unnecessarily and artificially excluded from being part of 5K1, in a manner that is inconsistent with the inventory decision for 505B. The artificial nature of the northern boundary of the excluded area is presumably due to being a grazing allotment boundary, but this is not important in the inventory and evaluation process. Area D3_5K3: This area encompasses the spectacular and highly scenic of Water Canyon Mesa and South and Sixmile Canyons, as well as higher terrain along the northeastern border of the Langmuir Research Site. Along with 5K1, 5K3 is a popular and widely used area for hiking and outdoor recreation, that is well qualified and suited for Wilderness designation. Area D3_Lang: Except for the high-use area in its northwestern-most part, which is excluded from the inventoried area, essentially all of the Langmuir Research area is highly qualified for wilderness designation. In effect, it is already being managed as wilderness, both by the Forest Service and by the Langmuir group at New Mexico Tech, of which I am a long-time member. It is good that the D3_Lang area has been added to the Phase 2 inventory, as this will allow it to be considered as an important part of a greater Magdalena Wilderness as the process goes forward. The atmospheric studies being conducted on thunderstorms and lightning over and around the area are world-class. These and the development of the Magdalena Ridge astronomical observatory, along with other studies, are being conducted in a manner that has minimal impact on the area's naturalness, and would be compatible with wilderness designation. While I would personally support such designation for much of the Research Site, I do not attempt speak for the Langmuir group on this matter. I would add that the Langmuir operations are fully respectful of the research area's wilderness values. Several years back, a long, heavy research cable suspended over Sawmill Canyon and associated support installations were personally dismantled and with considerable effort hauled out of the canyon by the Langmuir Chairperson and staff, leaving no trace of its earlier presence. Every effort is also made on a continuing basis to retrieve balloon-borne instruments and lightning-triggering rockets and associated paraphernalia used during the studies. The D3_Lang area also includes two portions of land adjacent to the Research Site, on the SE and SW corners of the FS boundary. The SW portion is adjacent to the BLM's Devil's Backbone Wilderness Study Area (WSA). As noted in the Inventory and Evaluation Process document, this in itself requires the area to be inventoried. The area is also well-qualified to be part of a Magdalena wilderness, either by itself or in conjuction with the DC3_Lang site if recommended for Wilderness designation.
