PLAN’s match, not yet checked by a personThe agency's own No Action discussion states that under the recently passed EXPLORE Act, climbing use in the project area 'including the Leigh Creek RNA' must continue as it currently exists because the Act protects continued use and maintenance of routes and fixed anchors that existed when it was signed in January 2025.
The agency's own No Action discussion states that under the recently passed EXPLORE Act, climbing use in the project area 'including the Leigh Creek RNA' must continue as it currently exists because the Act protects continued use and maintenance of routes and fixed anchors that existed when it was signed in January 2025.
The Proposed Action then closes all of Leigh Creek RNA to sport climbing and removes all 25 established routes there, without explaining why the EXPLORE Act protection the agency itself invokes does not bar this removal. The Forest Service should directly address the EXPLORE Act conflict and justify, in the decision document itself, why removing pre-existing protected routes and anchors is lawful.
A hole PLAN found in the agency’s own analysis
“The EXPLORE Act includes direction that provides for the continued use and maintenance of recreational climbing routes (including fixed anchors along the routes) in existence as of the date the EXPLORE Act was passed. Therefore, climbing use in the project area, including the Leigh Creek RNA, would continue as it currently exists.”

The Forest Service should explain why a determination that a species may trend toward federal listing does not require preparation of an environmental impact statement.
A hole PLAN found in the agency’s own analysis
“For fringed myotis and spotted bats, the effects determination is 'Will impact individuals or habitat with a consequence that the action may contribute to a trend towards federal listing or cause a loss of viability to the population or species.' However, as part of the route development guidelines outlined in the Proposed Action, route development would be prohibited where it would cause negative impacts to wildlife sensitive species.”

PLAN’s match, not yet checked by a personThe wildlife section states climbing currently affects about 22% of cliff habitat, but then separately states that unrestricted route development, the very scenario the Proposed Action's open-ended review process could allow over time, would affect approximately 88% of cliff habitat.
The wildlife section states climbing currently affects about 22% of cliff habitat, but then separately states that unrestricted route development, the very scenario the Proposed Action's open-ended review process could allow over time, would affect approximately 88% of cliff habitat.
The EA never analyzes what actual cap, if any, applies to cumulative future route development, leaving a four-fold jump in potential cliff habitat impact unaddressed as the basis for a FONSI. The Forest Service should analyze and disclose the reasonably foreseeable long-term cliff habitat impact of its review process, not just a bookend 'unrestricted' scenario, or explain what actually limits total development.
A hole PLAN found in the agency’s own analysis
“Unrestricted route development would affect approximately 88% of cliff habitat in the project area. This is a conservative estimate that assumes a 50-meter buffer from adopted NFS trails and maximum route development of cliffs in Tensleep Canyon.”

The EA documents that the Medicine Lodge elk herd is 2.9% below objective, the Paint Rock mule deer herd is 16.8% below objective, and the Southwest Bighorns mule deer herd is 58.8% below objective.
It then admits that expanding affected winter range from 23% to 27% means 'the Proposed Action would not contribute to the forest plan strategy to improve big game habitat value to support population objectives.' The agency proposes an action it acknowledges works against its own forest plan goal for herds already substantially below target. The Forest Service should explain why it is selecting an alternative that its own analysis says will not help, and may hinder, recovery of herds already below objective.
A hole PLAN found in the agency’s own analysis
“the Proposed Action would not contribute to the forest plan strategy to improve big game habitat value to support population objectives. However, design features would reduce short-term effects by restricting construction during seasonal wildlife closures (Wildlife 1), and reduce long-term effects by limiting new trails and staging areas in winter range and parturition habitat (Wildlife 1)”

Throughout the soil, wildlife, scenic, and safety sections, the EA analyzes effects of a parking lot on up to 2 acres of sagebrush/shrubland and soil, while repeatedly noting the exact site has not been chosen.
The agency is drawing conclusions about erosion potential, scenic screening, and wildlife impact for a facility whose location is still undetermined. The Forest Service should identify the parking lot site, or at minimum a defined set of candidate sites, and analyze site-specific effects before relying on this analysis to support a finding of no significant impact.
A hole PLAN found in the agency’s own analysis
“The parking lot would be approximately 2 acres and though the exact location will be determined after survey and design, it would be located in an area with soil types that have low soil erosion potential and no major limitations to ground-disturbing activities.”

The No Action discussion documents that dispersed camping within 100 feet of Tensleep Creek is currently out of compliance with the forest plan's Water Influence Zone standard.
Commenters asked for designated dispersed camping sites along Road 18 to fix this, but the responsible official pushed that idea out of this project as a separate future project, while the Proposed Action only prohibits camping on 1.5 of the road's 8 miles and relies on informal expectation that new sites will simply appear more than 100 feet from the creek. The Forest Service should explain how it will actually prevent new streamside camping without the designated-site tool it removed from this decision, or fold designated dispersed camping into this plan.
A hole PLAN found in the agency’s own analysis
“new sites would likely be established, which is allowed anywhere within 300 feet along Road 18, as long as the site is not within 100 feet of Tensleep Creek. Therefore, long-term negative impacts to camping are not expected.”

- Hold up

- Not fully backed
- 4
- Never analyzed
The Forest Service wants to adopt a climbing management plan for Tensleep Canyon that adds trails, toilets and a parking lot, ends camping along part of Road 18, closes Leigh Creek Research Natural Area to climbing, and allows new routes only after review. It says rising use is damaging soil, water, wildlife, plants and cultural resources and that the forest plan calls for such a plan.
“The Bighorn National Forest needs a climbing management plan to effectively manage rock climbing and associated recreational activities to support the continued opportunities for rock climbing, minimize user conflict, and protect the area’s resources in a manner that is consistent with the forest plan.”
Purpose and Need for the Proposal
EffectsNot fully backedThe review process for new routes will keep route development from harming sensitive wildlife and plant species.
The Proposed Action allows route development only where it wouldn't harm sensitive wildlife and plant species. Design features require site-specific surveys (Wildlife 2, Botany 2), limit development where raptor nests or bat roosts are found, and restrict work during seasonal closures. The document says its analyses assume all actions are implemented to estimate maximum effects, and the 88% figure is called a conservative estimate assuming maximum route development. So the listing-trend determinations for fringed myotis, spotted bats and Watson's prickly phlox are worst-case figures, not proof the review will fail. Still, the document doesn't explain how the review would judge harm, leaves the process to Appendix B, which isn't in this text, and never revises those determinations to credit the review.

EffectsNot fully backedInviting tribes to do traditional cultural surveys before implementation will ensure the plan doesn't cause irreversible harm to sacred rock and traditional use areas.
The plan invites tribes to do traditional cultural surveys before implementation (Cultural 2), limits new routes to reviewed areas, bans rock removal except for safety, and bans gluing, artificial holds and mechanically made holds. The survey promise covers traditional cultural use areas, not every rock. The document reports that several tribes see all canyon rock as sacred and bolting as irreversible harm, and it says the plan only attempts to strike a balance. It doesn't explain what happens if tribes decline to survey or how survey results would stop a route, so the word ensure isn't backed up.

The agency says
“To prevent negative impacts to traditional cultural use areas under the Proposed Action, the Forest Service will invite tribes to conduct traditional cultural surveys prior to implementation to ensure that management actions do not cause irreversible negative impacts (Cultural 2).”

EffectsNot fully backedA 50-space parking lot and signs will improve highway safety by reducing parking shortages and sudden moves in and out of traffic.
The agency's support is anecdotal reports of sudden stops at pullouts. The Wyoming Department of Transportation crash data for 2018 through 2022 showed 34 crashes, only one tied to a pull-off, and the document found no clear link to parking. It gives no count of how many cars now park at pullouts or whether 50 spaces meets demand.

EffectsNot fully backedWith its management recommendations, the plan will have no adverse effects on historic properties.
Archaeologists did a Class III intensive inventory of about 200 acres covering trails, possible toilet locations, parking and staging areas, and cliff faces for existing and future routes. They found no sites near proposed toilets and set conditions for eligible sites crossed by trails. The document says future development, including parking, will occur only inside the surveyed area, and areas with cultural resources will be left out. But the parking lot site isn't chosen, 14 sites across the analysis area remain unevaluated, and consultation on the determination is still pending, so the finding isn't final.

EffectsNot fully backedClosing 1.5 miles of Road 18 to camping and removing creekside sites won't have long-term negative effects on camping because new sites will be made.
The document says 26 sites remain along the 6.5 open miles of Road 18, only four of them would be removed, and new sites are allowed anywhere within 300 feet of the road if they're not within 100 feet of Tensleep Creek. But it doesn't show there's usable ground along those miles to replace the sites lost on the closed 1.5 miles plus the four creekside sites. Resource effects from new campsites are a separate question from camping opportunity.

Where its own record backs the agency
EffectsLosing the 25 routes in Leigh Creek Research Natural Area will be made up by new route development elsewhere.Why it holds +
The loss is 25 routes, about 2% of the roughly 1,350 in the project area. Only about 74 of the approximately 835 acres of cliff habitat have climbing routes, and the rest of the project area opens to reviewed route development. Some areas will be excluded for cultural and natural resources, and no count is given, but replacing 25 routes across that much undeveloped cliff is a reasonable conclusion from the document's own figures.
The agency says
“However, allowing for additional route development elsewhere in the project area would make up for this loss.”
Effects to recreation
Its own record backs it
“Areas that have cultural resources present will be omitted from designated locations where future climbing development can occur.”
Future Route Development - Review Process
ScienceSurveys found rock climbing was the only activity harming the values of Leigh Creek Research Natural Area, justifying its closure to climbing.Why it holds +
The document describes 2021 and 2023 botanical surveys finding Watson's prickly phlox next to bare climbing routes, frequent climbing use with spiderwebbed trails in the first quarter mile, and little other use: no horseback evidence, hiking limited to two climbing access trails, no ski use seen. That supports the finding.
The agency says
“Rock climbing was the only activity found to impact the RNA values and viability.”
Effects to Leigh Creek Research Natural Area
Its own record backs it
“Botanical surveys conducted in 2021 and 2023 noted Linanthus watsonii populations directly next to climbing routes on cliff walls, but noted climbing routes were completely devoid of vegetation.”
Effects to Leigh Creek Research Natural Area
“Climbing use was evident and frequent in the first ¼ mile of the western edge of the RNA, with many spiderwebbed access trails leading to the base of climbing routes and bouldering areas.”
