  • Harvey Butchart's Hiking Log DETAILED HIKING LOGS (January
    Harvey Butchart’s Hiking Log DETAILED HIKING LOGS (January 22, 1965 - September 25, 1965) Mile 24.6 and Hot Na Na Wash [January 22, 1965 to January 23, 1965] My guest for this trip, Norvel Johnson, thought we were going for just the day. When I told him it was a two day trip, he brought in his sleeping bag, but since he had no knapsack, we decided to sleep at the Jeep. The idea was to see Hot Na Na from the rim on Friday and then go down it as far as possible on Saturday. We thought we were following the Tanner Wash Quad map carefully when we left the highway a little to the north of the middle of the bay formed by Curve Wash in the Echo Cliffs. What we didn't realize is that there is another turnoff only a quarter of a mile north of the one we used. This is the way we came out of the hinterland on Saturday. Our exit is marked by a large pile of rocks and it gives a more direct access to all the country we were interested in seeing. The way we went in goes west, south, and north and we got thoroughly confused before we headed toward the rim of Marble Canyon. The track we followed goes considerably past the end of the road which we finally identified as the one that is one and a half miles north of Pine Reservoir. It ended near a dam. We entered the draw beyond the dam and after looking down at the Colorado River, decided that we were on the north side of the bay at Mile 24.6.

  • Clear-Water Tributaries of the Colorado River in the Grand Canyon, Arizona: Stream Ecology and the Potential Impacts of Managed Flow by René E
    Clear-water tributaries of the Colorado River in the Grand Canyon, Arizona: stream ecology and the potential impacts of managed flow by René E. Henery ABSTRACT Heightened attention to the sediment budget for the Colorado River systerm in Grand Canyon Arizona, and the importance of the turbid tributaries for delivering sediment has resulted in the clear-water tributaries being overlooked by scientists and managers alike. Existing research suggests that clear-water tributaries are remnant ecosystems, offering unique biotic communities and natural flow patterns. These highly productive environments provide important spawning, rearing and foraging habitat for native fishes. Additionally, clear water tributaries provide both fish and birds with refuge from high flows and turbid conditions in the Colorado River. Current flow management in the Grand Canyon including beach building managed floods and daily flow oscillations targeting the trout population and invasive vegetation has created intense disturbance in the Colorado mainstem. This unprecedented level of disturbance in the mainstem has the potential to disrupt tributary ecology and increase pressures on native fishes. Among the most likely and potentially devastating of these pressures is the colonization of tributaries by predatory non-native species. Through focused conservation and management tributaries could play an important role in the protection of the Grand Canyon’s native fishes. INTRODUCTION More than 490 ephemeral and 40 perennial tributaries join the Colorado River in the 425 km stretch between Glen Canyon Dam and Lake Mead. Of the perennial tributaries in the Grand Canyon, only a small number including the Paria River, the Little Colorado River and Kanab Creek drain large watersheds and deliver large quantities of sediment to the Colorado River mainstem (Oberlin et al.

Like a gift, booming streams of crystalline water emerge from mysterious caves to transform the harsh desert of the inner canyon into absurdly beautiful green oasis replete with the music of falling water and cool pools. Trailhead access can be difficult, sometimes impossible, and the approach march is long, hot and dry, but for those making the journey these destinations represent something close to canyon perfection.

  • GRAND CANYON GUIDE No. 6
    GRAND CANYON GUIDE no. 6 ... excerpted from Grand Canyon Explorer … Bob Ribokas AN AMATEUR'S REVIEW OF BACKPACKING TOPICS FOR THE T254 - EXPEDITION TO THE GRAND CANYON - MARCH 2007 Descriptions of Grand Canyon Layers Grand Canyon attracts the attention of the world for many reasons, but perhaps its greatest significance lies in the geologic record that is so beautifully preserved and exposed here. The rocks at Grand Canyon are not inherently unique; similar rocks are found throughout the world. What is unique about the geologic record at Grand Canyon is the great variety of rocks present, the clarity with which they're exposed, and the complex geologic story they tell. Paleozoic Strata: Kaibab depositional environment: Kaibab Limestone - This layer forms the surface of the Kaibab and Coconino Plateaus. It is composed primarily of a sandy limestone with a layer of sandstone below it. In some places sandstone and shale also exists as its upper layer. The color ranges from cream to a greyish-white. When viewed from the rim this layer resembles a bathtub ring and is commonly referred to as the Canyon's bathtub ring. Fossils that can be found in this layer are brachiopods, coral, mollusks, sea lilies, worms and fish teeth. Toroweap depositional environment Toroweap Formation - This layer is composed of pretty much the same material as the Kaibab Limestone above. It is darker in color, ranging from yellow to grey, and contains a similar fossil history. Coconino depositional environment: Coconino Sandstone - This layer is composed of pure quartz sand, which are basically petrified sand dunes. Wedge-shaped cross bedding can be seen where traverse-type dunes have been petrified.

  • NORTHERN ARIZONA PROVINCE (024) by W.C
    NORTHERN ARIZONA PROVINCE (024) By W.C. Butler INTRODUCTION This province covers about 59,000 sq mi, mostly in the southwestern part of the Colorado Plateau. Significant geologic features include the Grand Canyon, Kaibab Arch, Mogollon Highlands transition zone, Monument Uplift, Defiance Uplift, Black Mesa Basin, Holbrook Basin, and southern edges of the Kaiparowits and Blanding Basins. The stratigraphic section shown for northeastern Arizona has demonstrated the highest petroleum potential in Arizona. See Wilson (1962), Butler (1988a), and Dickinson (1989) for synopses of the province's geology and evolution. The lithologically and structurally complex basement of the Colorado Plateau area evolved from northwest-younging Proterozoic terranes sequentially accreted onto the Archean craton. As much as 12,000 ft of Middle and Late Proterozoic strata is preserved in possible rift-aulacogen depositional settings in central Arizona. Thick, unmetamorphosed, organic-rich Late Proterozoic strata deposited in backarc basins or continental lakes of north-central Arizona and south-central Utah have good petroleum potential. The plateau area, as a passive Paleozoic plate margin and buffered Mesozoic retro-arc platform, has been remarkably tectonically stable during Phanerozoic time. The area is characterized by blanket Paleozoic strata, as much as 6,000 ft thick, consisting of mostly shallow marine clastics and carbonates showing numerous disconformities. These strata accumulated during transgressions and regressions from both the northwest and southeast, onlapping and thinning toward the trans-continental arch – a northeast-trending positive area extending from the northeast into central Arizona. Convergence between North and South American tectonic plates, with reactivation of basement blocks, during the late Paleozoic created the plateau's fault-bounded basins and uplifts.
