Spence1 ABSTRACT.—Symphyotrichum expansum (Puepp ex Spreng.) Nesom is reported new to Utah from the Escalante River drainage. A major range extension is reported for Aralia racemosa L. in the Escalante drainage, and additional populations are reported of the rare species Imperata brevifolia Vasey in Utah, including the 1st record for the Grand Staircase–Escalante National Monument. Heterotheca grandiflora Nutt. is reported new to north central Arizona. New locations and notes on an additional 22 rare species in Glen Canyon National Recreation Area are listed. Key words: flora, Glen Canyon National Recreation Area, Utah, Arizona, relicts, dispersal. Intensive fieldwork in Glen Canyon National emerge at the Navajo-Kayenta interface. In Recreation Area (NRA) was conducted on addition to these records, new records for the riparian communities in side canyons around Colorado River below Glen Canyon Dam in Lake Powell between 1991 and 2002 (cf.

  • PRELUDE to SEVEN SLOTS: FILLING and SUBSEQUENT MODIFICATION of SEVEN BROAD CANYONS in the NAVAJO SANDSTONE, SOUTH-CENTRAL UTAH by David B
    PRELUDE TO SEVEN SLOTS: FILLING AND SUBSEQUENT MODIFICATION OF SEVEN BROAD CANYONS IN THE NAVAJO SANDSTONE, SOUTH-CENTRAL UTAH by David B. Loope1, Ronald J. Goble1, and Joel P. L. Johnson2 ABSTRACT Within a four square kilometer portion of Grand Staircase-Escalante National Monument, seven distinct slot canyons cut the Jurassic Navajo Sandstone. Four of the slots developed along separate reaches of a trunk stream (Dry Fork of Coyote Gulch), and three (including canyons locally known as “Peekaboo” and “Spooky”) are at the distal ends of south-flowing tributary drainages. All these slot canyons are examples of epigenetic gorges—bedrock channel reaches shifted laterally from previous reach locations. The previous channels became filled with alluvium, allowing active channels to shift laterally in places and to subsequently re-incise through bedrock elsewhere. New evidence, based on optically stimulated luminescence (OSL) ages, indicates that this thick alluvium started to fill broad, pre-existing, bedrock canyons before 55,000 years ago, and that filling continued until at least 48,000 years ago. Streams start to fill their channels when sediment supply increases relative to stream power. The following conditions favored alluviation in the study area: (1) a cooler, wetter climate increased the rate of mass wasting along the Straight Cliffs (the headwaters of Dry Fork) and the rate of weathering of the broad outcrops of Navajo and Entrada Sandstone; (2) windier conditions increased the amount of eolian sand transport, perhaps destabilizing dunes and moving their stored sediment into stream channels; and (3) southward migration of the jet stream dimin- ished the frequency and severity of convective storms.

  • Conceptual Design Documentation
    Appendix A: Conceptual Design Documentation APPENDIX A Conceptual Design Documentation June 2019 A-1 APPENDIX A: CONCEPTUAL DESIGN DOCUMENTATION The environmental analyses in the NEPA and CEQA documents for the proposed improvements at Oceano County Airport (the Airport) are based on conceptual designs prepared to provide a realistic basis for assessing their environmental consequences. 1. Widen runway from 50 to 60 feet 2. Widen Taxiways A, A-1, A-2, A-3, and A-4 from 20 to 25 feet 3. Relocate segmented circle and wind cone 4. Installation of taxiway edge lighting 5. Installation of hold position signage 6. Installation of a new electrical vault and connections 7. Installation of a pollution control facility (wash rack) CIVIL ENGINEERING CALCULATIONS The purpose of this conceptual design effort is to identify the amount of impervious surface, grading (cut and fill) and drainage implications of the projects identified above. The conceptual design calculations detailed in the following figures indicate that Projects 1 and 2, widening the runways and taxiways would increase the total amount of impervious surface on the Airport by 32,016 square feet, or 0.73 acres; a 6.6 percent increase in the Airport’s impervious surface area. Drainage patterns would remain the same as both the runway and taxiways would continue to sheet flow from their centerlines to the edge of pavement and then into open, grassed areas. The existing drainage system is able to accommodate the modest increase in stormwater runoff that would occur, particularly as soil conditions on the Airport are conducive to infiltration. Figure A-1 shows the locations of the seven projects incorporated in the Proposed Action.

    Literature Cited Robert W. Kiger, Editor This is a consolidated list of all works cited in volumes 19, 20, and 21, whether as selected references, in text, or in nomenclatural contexts. In citations of articles, both here and in the taxonomic treatments, and also in nomenclatural citations, the titles of serials are rendered in the forms recommended in G. D. R. Bridson and E. R. Smith (1991). When those forms are abbre- viated, as most are, cross references to the corresponding full serial titles are interpolated here alphabetically by abbreviated form. In nomenclatural citations (only), book titles are rendered in the abbreviated forms recommended in F. A. Stafleu and R. S. Cowan (1976–1988) and F. A. Stafleu and E. A. Mennega (1992+). Here, those abbreviated forms are indicated parenthetically following the full citations of the corresponding works, and cross references to the full citations are interpolated in the list alphabetically by abbreviated form. Two or more works published in the same year by the same author or group of coauthors will be distinguished uniquely and consistently throughout all volumes of Flora of North America by lower-case letters (b, c, d, ...) suffixed to the date for the second and subsequent works in the set. The suffixes are assigned in order of editorial encounter and do not reflect chronological sequence of publication. The first work by any particular author or group from any given year carries the implicit date suffix “a”; thus, the sequence of explicit suffixes begins with “b”. Works missing from any suffixed sequence here are ones cited elsewhere in the Flora that are not pertinent in these volumes.
