  • WPLI Resolution
    Matters from Staff Agenda Item # 17 Board of County Commissioners ‐ Staff Report Meeting Date: 11/13/2018 Presenter: Alyssa Watkins Submitting Dept: Administration Subject: Consideration of Approval of WPLI Resolution Statement / Purpose: Consideration of a resolution proclaiming conservation principles for US Forest Service Lands in Teton County as a final recommendation of the Wyoming Public Lands Initiative (WPLI) process. Background / Description (Pros & Cons): In 2015, the Wyoming County Commissioners Association (WCCA) established the Wyoming Public Lands Initiative (WPLI) to develop a proposed management recommendation for the Wilderness Study Areas (WSAs) in Wyoming, and where possible, pursue other public land management issues and opportunities affecting Wyoming’s landscape. In 2016, Teton County elected to participate in the WPLI process and appointed a 21‐person Advisory Committee to consider the Shoal Creek and Palisades WSAs. Committee meetings were facilitated by the Ruckelshaus Institute (a division of the University of Wyoming’s Haub School of Environment and Natural Resources). Ultimately the Committee submitted a number of proposals, at varying times, to the BCC for consideration. Although none of the formal proposals submitted by the Teton County WPLI Committee were advanced by the Board of County Commissioners, the Board did formally move to recognize the common ground established in each of the Committee’s original three proposals as presented on August 20, 2018. The related motion stated that the Board chose to recognize as a resolution or as part of its WPLI recommendation, that all members of the WPLI advisory committee unanimously agree that within the Teton County public lands, protection of wildlife is a priority and that there would be no new roads, no new timber harvest except where necessary to support healthy forest initiatives, no new mineral extraction excepting gravel, no oil and gas exploration or development.

  • Sensitive and Rare Plant Species Inventory in the Salt River and Wyoming Ranges, Bridger-Teton National Forest
    Sensitive and Rare Plant Species Inventory in the Salt River and Wyoming Ranges, Bridger-Teton National Forest Prepared for Bridger-Teton National Forest P.O. Box 1888 Jackson, WY 83001 by Bonnie Heidel Wyoming Natural Diversity Database University of Wyoming Dept 3381, 1000 E. University Avenue University of Wyoming Laramie, WY 21 February 2012 Cooperative Agreement No. 07-CS-11040300-019 ABSTRACT Three sensitive and two other Wyoming species of concern were inventoried in the Wyoming and Salt River Ranges at over 20 locations. The results provided a significant set of trend data for Payson’s milkvetch (Astragalus paysonii), expanded the known distribution of Robbin’s milkvetch (Astragalus robbinsii var. minor), and relocated and expanded the local distributions of three calciphilic species at select sites as a springboard for expanded surveys. Results to date are presented with the rest of species’ information for sensitive species program reference. This report is submitted as an interim report representing the format of a final report. Tentative priorities for 2012 work include new Payson’s milkvetch surveys in major recent wildfires, and expanded Rockcress draba (Draba globosa) surveys, both intended to fill key gaps in status information that contribute to maintenance of sensitive plant resources and information on the Forest. ACKNOWLEDGEMENTS All 2011 field surveys of Payson’s milkvetch (Astragalus paysonii) were conducted by Klara Varga. These and the rest of 2011 surveys built on the 2010 work of Hollis Marriott and the earlier work of she and Walter Fertig as lead botanists of Wyoming Natural Diversity Database. This project was initially coordinated by Faith Ryan (Bridger-Teton National Forest), with the current coordination and consultation of Gary Hanvey and Tyler Johnson.

  • Formation of Low-Δ18o Rhyolites After Caldera Collapse at Yellowstone, Wyoming, USA
    Formation of low-δ18O rhyolites after caldera collapse at Yellowstone, Wyoming, USA Ilya N. Bindeman John W. Valley Department of Geology and Geophysics, University of Wisconsin, 1215 West Dayton Street, Madison, Wisconsin 53706, USA ABSTRACT We present a new model for the genesis of low-δ18O rhyolites of the Yellowstone caldera based on analyses of zircons and individual quartz phenocrysts. Low-δ18O rhyolites were erupted soon after the massive caldera-forming Lava Creek Tuff eruption (602 ka, ~1000 km3) and contain xenocrysts of quartz and zircon inherited from precaldera rhyolites. These zircons are iso- topically zoned and out of equilibrium with their host low-δ18O melts and quartz. Diffusion modeling predicts that magmatic disequilibria of oxygen isotopes persists for as much as tens of thousands of years following nearly total remelting of the hydrothermally altered igneous roots of the depressed cauldron, in which the alteration-resistant quartz and zircon initially retained their δ18O values. These results link melting to caldera collapse, rule out rapid or catastrophic magma–meteoric water interaction, and indicate wholesale melting rather than assimilation or partial melting.

    From: Jackson Hole Children"s Museum To: Arne Jorgensen Subject: Time is Running Out! Date: Thursday, July 29, 2021 10:24:21 AM View this email in your browser "During a year of so much uncertainty, our family was so grateful to have the resources and support of local preschool programs at Children’s Learning Center, Jackson Hole Children’s Museum and Teton Literacy Center. It brought us peace of mind to know that there were caring, professional educators working to minimize the impact of this difficult year on our kids." – Jackson Hole Parent SEE ALL STORIES Hello friends and supporters, You’ve heard it before: kids are resilient. They’re capable of navigating big challenges and being okay. But with the help of caring teachers and peers, their chances are even better. When kids have professional support, guidance, and excellent education, they’re significantly more likely to come out of a challenging time — like the pandemic — with healthy social, emotional, and academic skills and on-track development. The Jackson Hole Children’s Museum, Teton Literacy Center, and Children’s Learning Center are dedicated to collaborating and implementing innovative programming to maximize the resilience of local kids in this critical moment. With programming that includes experience-based curricula as well as an expanded focus on social-emotional development, our organizations are teaming up to ensure that kids have every chance to be as resilient as possible. Your support of Champions for Children will empower us to continue this critical work. Healthy, happy kids make for healthy, happy families — which in turn makes for a thriving workforce, economy, and community.

  • Basic Seismological Characterization for Sublette County, Wyoming By
    Basic Seismological Characterization for Sublette County, Wyoming by James C. Case, Rachel N. Toner, and Robert Kirkwood Wyoming State Geological Survey September 2002 BACKGROUND Seismological characterizations of an area can range from an analysis of historic seismicity to a long-term probabilistic seismic hazard assessment. A complete characterization usually includes a summary of historic seismicity, an analysis of the Seismic Zone Map of the Uniform Building Code, deterministic analyses on active faults, “floating earthquake” analyses, and short- or long- term probabilistic seismic hazard analyses. Presented below, for Sublette County, Wyoming, are an analysis of historic seismicity, an analysis of the Uniform Building Code, deterministic analyses of nearby active faults, an analysis of the maximum credible “floating earthquake”, and current short- and long-term probabilistic seismic hazard analyses. Historic Seismicity in Sublette County The enclosed map of “Earthquake Epicenters and Suspected Active Faults with Surficial Expression in Wyoming” (Case and others, 1997) shows the historic distribution of earthquakes in Wyoming. Eighteen magnitude 2.5 or intensity III and greater earthquakes have been recorded in Sublette County. On October 24, 1936, two earthquakes occurred in western Wyoming. The U.S.G.S. National Earthquake Information Center reported these two intensity III earthquakes as occurring in Sublette County, approximately 3 miles southwest of Cora. The original reference and description of these events, however, indicates that these earthquakes originated in the Star Valley of Lincoln County (Neumann, 1936). In June of 1945, two earthquakes occurred in southwestern Sublette County. These intensity III earthquakes were recorded on June 7, 1945, approximately 4 miles northwest of Calpet, and on June 23, 1945, approximately 3 miles northeast of Calpet.
