  • USA Reisebericht 2009
    Tag 12 (Dienstag, 14.7.2009 – Cathedral Valley Day) Torrey, UT Heute morgen wurde ich erst um 6:55 Uhr wach – recht spät. Trotzdem waren wir relativ schnell, so dass wir schon um 8:30 Uhr im Auto saßen und um 9:00 an der River Ford standen, um den Loop durch das Cathedral Valley zu beginnen. Und zwar über die Harnett Road. Und es wird sich gelohnt haben. Während ich die Furt (River Ford) durchfahre, begleitet mich Barbara außerhalb des Autos im Wasser. Es geht ohne Probleme. Danach ist die Hartnett Road allerdings noch mit tiefem Sand versehen, so dass wir erst mal ein wenig mit dem 4WD durchflügen müssen. Insgesamt liegen inkl. Abstechern 66 Meilen auf Dirt Roads vor uns. Die ersten Meilen auf der Hartnett Road sind unterschiedlicher Qualität aber eigentlich gut zu fahren. Erster Stopp ist dann an den Bentonite Hills, gerundete bunte Hügel. Danach geht es weiter zum Lower South Desert Overlook, der auf einer einer Meilen langen Stichstraße von der Hartnett Road zu erreichen ist. Vom Parkplatz muss man dann noch eine Viertel Meile bis zum Rand laufen, an dem man einen Blick auf die Lower South Desert hat, die parallel zur Waterpocket Fold verläuft. Direkt vor dem Overlook liegt ein 500 Fuß hoher Sandstein Monolith aus Entrada Sandstone, der Jailhouse Rock. Danach geht es durch eine wüstenhafte Hochebene, genannt The Hartnett, nach der auch die Straße ihren Namen hat. Hier erreicht man auch wieder den Capitol Reef Nationalpark, die Zufahrten liegen außerhalb. Den Lower Cathedral Valley Overlook lassen wir allerdings rechts liegen, da man bis zum Overlook eine Meile Cross-Country laufen müsste – und dazu habe ich keine Lust.

  • Draft RECOVERY PLAN
    Winkler cactus (Pediocactus winkleri) AND San Rafael cactus (Pediocactus despainii) Draft RECOVERY PLAN December 2015 U.S. Fish and Wildlife Service, Denver, Colorado DISCLAIMER Recovery plans use the best available information to identify reasonable actions for protecting and recovering listed species. Plans are published by the U.S. Fish and Wildlife Service (USFWS) and are sometimes prepared with the assistance of recovery teams, contractors, State agencies, or others. Attainment of recovery objectives and availability of funds are subject to budgetary and other constraints as well as the need to address other priorities. Nothing in this plan should be construed as a commitment or requirement for any Federal agency to obligate or pay funds in contravention of the Anti-Deficiency Act, 31 U.S.C. 1341, or any other law or regulation. Recovery plans do not necessarily represent the views, official position, or approval of any individuals or agencies involved in plan formulation other than the U.S. Fish and Wildlife Service. They represent the official position of the U.S. Fish and Wildlife Service only after they have been signed by the Regional Director. Approved plans are subject to modification as dictated by new findings, changes in species status, and the completion of recovery actions. The literature citation for this document should read: U.S. Fish and Wildlife Service (USFWS). 2015. Winkler cactus (Pediocactus winkleri) and San Rafael cactus (Pediocactus despainii) recovery plan.

  • Hiking Routes in Capitol Reef's Cathedral District
    Capitol Reef National Park National Park Service U.S. Department of the Interior Hiking Routes in Capitol Reef’s Cathedral District A remote backcountry with no paved roads, Capitol Reef’s northern Cathedral District features stark landscapes and a high degree of solitude. Here the northern flanks of Waterpocket Fold give way to broad deserts, stunning monoliths, and volcanic dikes and crags. The Cathedral and Hartnet roads (passable only to high- clearance vehicles; four-wheel drive often recommended) provide access to a number of short hikes, a selection of which is described here. These routes are not official, maintained trails. Route conditions, including obstacles in canyons, change frequently due to weather, flash floods, rockfall, and other hazards. Routefinding, navigation, and map-reading skills are critical. Do not rely solely on unofficial route markers (rock cairns, etc.); they are not maintained by the National Cathedral Valley Park Service (NPS), may not indicate the route in this description, or may be absent. Roads in this area are maintained infrequently and are not plowed in winter. Some sections of road cross areas of bentonite clay, which becomes impassable when wet. Deep, soft sand may also exist on roads. Roads may occasionally require four-wheel drive, and may quickly become impassable due to wet weather. At the south end of the Hartnet Road near Highway 24, vehicles must ford the Fremont River; there is no bridge over the river. Do not attempt to cross the river during floods or other periods of high water. Ask at the visitor center about river ford conditions. Check weather forecasts and road reports before departing.

  • Cathedral Valley - Hartnet Road
    Cathedral Valley - Hartnet Road Autor: Gerd Jäger Die Hartnet Road oder die westliche Hälfte des Cathedral Valley Loop beginnt 11,7 Meilen östlich des Capitol Reef Visitor Center. Für diese Route benötigt man ein 4WD Vehicle, mindestens aber ein Fahrzeug mit HC, da man gleich zu Beginn den Fremont River durchqueren muss. Die Furt ist die meiste Zeit des Jahres passierbar, aber nach Regenfällen und im Frühjahr nach der Schneeschmelze kann der Wasserstand selbst für ein 4WD oder HC Fahrzeug zu hoch sein. Bei Nässe (Regen) ist die Road im weiteren Verlauf unpassierbar. Vor der Fahrt sollte man sich daher im Capitol Reef Visitor Center nach den Road- und Wetterverhältnissen erkundigen. Karte wurde mit Topo USA von DeLorme www.delorme.com erstellt 1 Meile 0,6 - River Furt Man erreicht das Südufer des Fremont Rivers. Im Wasser fährt man auf der rechten Seite etwa 30 Meter flussabwärts. Auf der anderen Seite des Rivers sieht Cathedral Valley - Hartnet Road 1 © Gerd Jäger http://www.westernladys-world.net/infos/ut_cathedral_valley_hartnet_road.php man die Fortsetzung der Straße. Wenn man in Höhe dieser Stelle ist durchquert man den Fluss und fährt dann auf der linken Seite hinaus. Das Wasser ist selten mehr als 30 cm tief. (Das Bild mit der eingezeichneten Linie ist quasi der „Blick zurück“, also nach Durchquerung der Furt.) Nach der Furt schlängelt sich die Road aufwärts durch abgerundete vielfarbige Hügel auf eine Bench oberhalb des Rivers. 2 Meile 1,8 - Rainbow Hills Diese braun-rot, grau-grün, blau und violett gebänderten Hügel sind nicht nur entlang der Hartnet Road sondern auch in der Middle Desert zu finden.

  • Capitol Reef General Management Plan
    final environmental impact statement general management plan development concept plan CAPITOL REEF NATIONAL PARK – UTAH Final Environmental Impact Statement General Management Plan Development Concept Plan CAPITOL REEF NATIONAL PARK September, 1998 This Final General Management Plan/Development Concept Plan presents four alternatives for the management, use, and development of Capitol Reef National Park over the next 15 years. The preferred alternative is designed to protect and preserve exceptional resources, the quality of visitor experience, and the wilderness characteristics of certain portions of the park. The objectives reflect the purpose for which the area was originally set aside (Presidential Proclamations 2246, 3249, and 3888): to reserve in the public interest the Waterpocket Fold and other features and objects of scientific interest. Resources of particular concern include a variety of geological features, strata, and mineral deposits; biologically productive riparian areas; water quality in park streams and the natural “waterpockets” for which the fold is named; air quality, scenic vistas, and night sky vistas; endangered, sensitive, protected, and candidate plant and animal species; the park’s biological diversity; and Capitol Reef’s archeological and historic resources, particularly the rural historic landscape of Fruita. Alternative A, the preferred alternative, emphasizes wilderness preservation and resource protection while still accommodating a variety of park uses and ensuring quality visitor experiences. Alternative B focuses on removing many existing developments, to restore and enhance natural resources and wilderness qualities of the park. Alternative C, the 1982 General Management Plan, emphasizes visitor services and facilities, including development in some backcountry areas. Alternative D, the No Action Plan, would maintain visitor services and resource protection at current levels throughout the 15-year life of the plan.

Free brochures are available for travelers at the Visitor Center. Don't miss this opportunity as Capitol Reef, more than any other park, gives you tremen- dous insight into the geologic history of the Colorado Plateau—the essential ingredient behind these landscapes that we so much admire today. Torrey, a small town at the west entrance of the park, makes a perfect base for your explorations. Over the course of the last few years, Torrey has seen a great deal of expansion: Where in the 1980's there wasn't a single motel, now there are almost a dozen vying for your business. The beautiful oasis of Fruita, inside the park, is especially nice if you are car camping or want to pitch a tent. During autumn and springtime, it is one of the most pleasant campgrounds anywhere. Panorama Point Coming from Torrey on UT 24, you discover a superlative road, bordered to the north by impressive cliffs that become even more spectacular during the golden hour, mornings and evenings. Among the formations at the base of the cliffs are Chimney Rock and the Castle. Chimney Rock isn’t really awesome in The Castle at dawn itself, but it photographs nicely in the afternoon from the parking area, when the dark red Moenkopi formation capped by the white Shinarump sandstone really CAPITOL REEF stands out. As for the Castle, it offers a remarkable collection of sedimentary lay- ers that can be enjoyed right by the side of the road.

  • Northern Colorado Plateau Herpetofauna Inventory 2001 Annual Report
    Northern Colorado Plateau Network Herpetofauna Inventory Northern Colorado Plateau Herpetofauna Inventory 2001 Annual Report Tim Graham and Renata Platenberg USGS Canyonlands Field Station, 2290 S West Resource Blvd. Moab, UT 84532 12 October 2001 Introduction Eight National Parks and Monuments in the Northern Colorado Plateau Network were surveyed for the presence of reptiles and amphibians from May to September 2001. Parks surveyed were: Bryce Canyon NP (BRCA), Capitol Reef NP (CARE), Cedar Breaks NM (CEBR), Fossil Butte NM (FOBU), Golden Spike NHS (GOSP), Pipe Spring NM (PISP), Timpanogos Cave NM (TICA), and Zion NP (ZION). The primary objective of the study was to provide a baseline inventory of herpetofauna in each park with the goal of documenting 90% of species present over two years of surveys. A secondary aim is to determine general abundance and distribution of species present, identifying park-specific species of special concern. The level of existing information on reptiles and amphibians in these parks varies from little or none to moderate amounts. For the majority of parks surveyed this year, even baseline information on species presence/absence was lacking. Attempts were made to identify gaps in knowledge and to structure surveys accordingly. The herpetofauna survey crew consisted of Tim Graham, Principal Investigator; Renata Platenberg, Crew Leader; and three Biological Science Technicians (Kim Galvin, Rebecca Harms and Jason Leon Jones). The crew generally worked as two independent units of two members each, enabling effort to be more widespread. Contact was maintained between the field crews and PI throughout the summer. Field summaries were provided to the PI in writing throughout the survey period.
