THE GAUE THAT TRAPPED HISTORY Natural Trap Cave has been collecting bones of unwary animals for at least 13,000 years. Expeditions led by a Mizzou anthropologist are digging up those bones and clues about the cycles of climatic change. Text and Photos by Dave Holman IIi / m ISSOllRI ilLUrnrus The only entrenee to Natural Trap Ceve la the hole In the roof. Any enlmal that might have survived the fallatlll became a victim. Workera at theahe, below, ehherrappellnto theeave or descend theacafloldlng. A herd of small horses stampeded through the tall grass across a plateau near the edge of a canyon, pur sued by a large, long-legged cat. The cat closed on the slowest horse, forcing her along the canyon edge onto a peninsula of limestone. The cat sprang, fas tened its claws and teeth in the horse's neck, and suddenly, horse and cat disappeared from the face of the earth. Twelve thousand years later, a green panel truck and a dusty jeep bounced along a dirt road over the same plateau, now covered with sage and prickly pear. On the limestone peninsula where the horse and cat disappeared, the vehicles stopped by a 15- foot-wide hole in the rock. Eighty feet below is the floor of Natural Trap Cave. The cave floor is covered with the accumulated dust of centuries, clearly stratified and containing thou sands of bones of animals that failed to see the hole. This summer was the second consecutive year that Bob Gilbert, research associate in Mizzou's an thropology department had led an organized ex pedition to the trap. -
Summary of Public Comments on Initial Draft Permit WY0002062 and WDEQ Response
Summary of Public Comments on Initial Draft Permit WY0002062 and WDEQ Response: Summary of Public Comments WDEQ Response Water quality model inadequate, inaccurate: The revised draft permit caps the load for Total Multiple concerns were cited regarding the applicant’s Dissolved Solids (TDS) at the existing permitted level of GEMSS mixing model predictions for water quality in 908 tons per month. Because the load and flow from the Boysen Reservoir and the Wind River Canyon, along facility will not be expanded with this revised permit with WDEQ’s review of the model. The model was renewal, WDEQ is not relying on the applicant’s GEMSS used because the applicant was proposing to model. significantly increase flow volumes and loads from this project, and WDEQ required the applicant to demonstrate that no adverse impacts would occur in waters within Boysen Reservoir or the Wind River Canyon. Public concerns included WDEQ’s use of a baseline water quality period in the Wind River (2010- 2016) that occurred during peak discharge years under Aethon’s predecessor Encana Oil and Gas, rather than pre-discharge; along with various other concerns raised about input and algorithm issues which could impact the accuracy of the model and make its results difficult to reproduce independently. Recreational, fish and aquatic life uses in Boysen The revised draft permit includes conditions to protect Reservoir and Wind River Canyon: water quality in Boysen Reservoir and the Wind River Many comments mentioned personal and commercial Canyon. All effluent limits established in this draft use of Boysen Reservoir and Wind River Canyon for permit are set to protect the existing and designated uses fishing, swimming, boating and guiding, as well as the within these water bodies, including primary contact need to protect fish and aquatic life habitat there. -

Exploring Grand Teton National Park
05 542850 Ch05.qxd 1/26/04 9:25 AM Page 107 5 Exploring Grand Teton National Park Although Grand Teton National Park is much smaller than Yel- lowstone, there is much more to it than just its peaks, a dozen of which climb to elevations greater than 12,000 feet. The park’s size— 54 miles long, from north to south—allows visitors to get a good look at the highlights in a day or two. But you’d be missing a great deal: the beautiful views from its trails, an exciting float on the Snake River, the watersports paradise that is Jackson Lake. Whether your trip is half a day or 2 weeks, the park’s proximity to the town of Jackson allows for an interesting trip that combines the outdoors with the urbane. You can descend Grand Teton and be living it up at the Million Dollar Cowboy Bar or dining in a fine restaurant that evening. The next day, you can return to the peace of the park without much effort at all. 1 Essentials ACCESS/ENTRY POINTS Grand Teton National Park runs along a north-south axis, bordered on the west by the omnipresent Teton Range. Teton Park Road, the primary thoroughfare, skirts along the lakes at the mountains’ base. From the north, you can enter the park from Yellowstone National Park, which is linked to Grand Teton by the John D. Rockefeller Jr. Memorial Parkway (U.S. Hwy. 89/191/287), an 8-mile stretch of highway, along which you might see wildlife through the trees, some still bare and black- ened from the 1988 fires. -
Quaternary Records of the Dire Wolf, Canis Dirus, in North and South America
Quaternary records of the dire wolf, Canis dirus, in North and South America ROBERT G. DUNDAS Dundas, R. G. 1999 (September): Quaternary records of the dire wolf, Canis dirus, in North and South Ameri- ca. Boreas, Vol. 28, pp. 375–385. Oslo. ISSN 0300-9483. The dire wolf was an important large, late Pleistocene predator in North and South America, well adapted to preying on megaherbivores. Geographically widespread, Canis dirus is reported from 136 localities in North America from Alberta, Canada, southward and from three localities in South America (Muaco, Venezuela; Ta- lara, Peru; and Tarija, Bolivia). The species lived in a variety of environments, from forested mountains to open grasslands and plains ranging in elevation from sea level to 2255 m (7400 feet). Canis dirus is assigned to the Rancholabrean land mammal age of North America and the Lujanian land mammal age of South Amer- ica and was among the many large carnivores and megaherbivores that became extinct in North and South America near the end of the Pleistocene Epoch.

Martin2 1The Arthritis Center of Northeast Ohio, University of Kansas Museum of Natural History, Carnegie Museum of Natural History, Northeastern Ohio Universities College of Medicine and University of Akron; 2Museum of Natural History and Department of Systematics and Ecology, University of Kansas, Lawrence, Kansas 66045 RIASSUNTO Nel presente studio vengono riportati i rilievi paleopatologici, con particolare riguardo alla presenza di artrite ero- siva, di osteoartrosi, di DISH , nonché ai segni di danno della dentizione, relativi ad un’ampia popolazione di mam- miferi, i cui resti (più di 30.000 ossa di 24 specie diverse) sono stati ritrovati nella Natural Trap Cave, Wyoming, USA. L’evidenza di artrite erosiva è confinata ai bovidi, Bison, Ovis e Bootherium, fatto osservabile anche in bisonti del tardo Pleistocene ritrovati nel Kansas (Twelve Mile Creek) e in un’altra località del Wisconsin, riferibile cronologi- camente al primo Olocene. Questi dati, ovvero la restrizione di tali segni di patologia articolare ad un singolo gene- re animale (Bovidi) e ad un determinato periodo storico, rende plausibile l’ipotesi che un agente patogeno, identifi- cabile col Mycobacterium tubercolosis, possa essere stato implicato nella genesi dell’artrite erosiva. Osteoartrosi e DISH sono risultate poco rappresentate nella popolazione animale della Natural Trap Cave, anche se il genere Bi- son ha dimostrato una discreta prevalenza di segni di osteoartrosi. -

Lee Lyman* (Department of Anthropology, 107 Swallow Hall, University of Missouri-Columbia, Columbia MO 65211, USA) Received 9 May 2008; revised manuscript accepted 30 June 2008 Abstract: Historical data are incomplete regarding the presence/absence and distribution of bighorn sheep (Ovis canadensis) in eastern Washington State. Palaeozoological (archaeological and palaeontological) data indicate bighorn were present in many areas there during most of the last 10 000 years. Bighorn occupied the xeric shrub-steppe habitats of the Channeled Scablands, likely because the Scablands provided the steep escape terrain bighorn prefer. The relative abundance of bighorn is greatest during climatically dry intervals and low during a moist period. Bighorn remains tend to increase in relative abundance over the last 6000 years. -
Bighorn River Basin, Wyoming
Environmental and Recreational Water Use Analysis for the Wind – Bighorn River Basin, Wyoming Wind – Bighorn River Basin Plan Update Prepared for: Wyoming Water Development Commission 6920 Yellowstone Rd Cheyenne, Wyoming 82009 Prepared by: Western EcoSystems Technology, Inc. 415 W. 17th St., Suite 200 Cheyenne, Wyoming 82001 September 7, 2017 Draft Pre-Decisional Document - Privileged and Confidential - Not For Distribution Wind – Bighorn River Basin Plan Update EXECUTIVE SUMMARY In 2010, the Wyoming Water Development Commission (WWDC) requested a study to develop more robust and consistent methods for defining environmental and recreational (E&R) water uses for the River Basin Planning program. The study outlined that recreational and environmental uses needed to be identified and mapped, in a way that would assess their interactions with traditional water uses throughout the state of Wyoming. Harvey Economics completed the study in 2012, with a report and handbook being produced to identify a consistent viewpoint and accounting process for E&R water demands and to help guide river basin planning efforts in moving forward. The methods developed in the handbook were implemented on the Wind-Bighorn River Basin (Basin), and the results of the Basin plan update are provided in this report. In addition to the handbook guidelines, Western Ecosystems Technology, Inc. coordinated with the WWDC to further the analysis through the development of three models: 1) protection, 2) environmental, and 3) recreation. The Basin is located in central and northwestern Wyoming. Approximately 80% of Yellowstone National Park (YNP) is included in the Basin. Elevations in the Basin are variable as the Wind River and Bighorn Mountains funnel water from alpine areas to lower river corridors. -

The Merlon, North Face: Three New Routes United States, Wyoming, Bighorn Mountains the Glacier Was Calving Every Half Hour All Day and All Night
AAC Publications The Merlon, North Face: Three New Routes United States, Wyoming, Bighorn Mountains The glacier was calving every half hour all day and all night. A thundering boom would reverberate off the narrow cirque walls, then a wave of water would roll across Glacier Lake. During the day we could get used to it, but at night the detonations would blast us right out of our dreams. This was my fifth climbing trip into the Cloud Peak Wilderness, but my first to the cirque below Cloud Peak’s tremendous east face. It was mid-August and I’d come in with two fellow Wyoming climbers: towering, pencil-thin Julian Poush and Chris “Slim” Murray. Poush’s father had actually attempted a route in this cirque over 40 years ago. We had help from horse packers getting our gear to the west end of Cloud Peak Reservoir, then humped heavy packs up past Diamond Lake, from which we scrambled northwest, gaining 700 feet to reach Glacier Lake (11,490’). Our goal was to climb the north face of the Merlon, a separate tower (ca. 13,200’) just south of Cloud Peak’s east face. We accomplished this the first day: Jenga (8 pitches, 5.8 R). We rapped off the eastern prow of the Merlon, replacing old slings that Ken Duncan and I had put in eight years earlier when we climbed No Climb For Old Men on the south face. [Editor’s note: The Merlon was first climbed, by its eastern buttress, in 1961. The south face was first climbed in the 1970s, though the exact line is unknown; the south face has three known routes, all 5.11. -
