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. -

The National Park System
January 2009 Parks and Recreation in the United States The National Park System Margaret Walls BACKGROUNDER 1616 P St. NW Washington, DC 20036 202-328-5000 www.rff.org Resources for the Future Walls Parks and Recreation in the United States: The National Park System Margaret Walls∗ Introduction The National Park Service, a bureau within the U.S. Department of the Interior, is responsible for managing 391 sites—including national monuments, national recreation areas, national rivers, national parks, various types of historic sites, and other categories of protected lands—that cover 84 million acres. Some of the sites, such as Yellowstone National Park and the Grand Canyon, are viewed as iconic symbols of America. But the National Park Service also manages a number of small historical sites, military parks, scenic parkways, the National Mall in Washington, DC, and a variety of other protected locations. In this backgrounder, we provide a brief history of the Park Service, show trends in land acreage managed by the bureau and visitation at National Park Service sites over time, show funding trends, and present the challenges and issues facing the Park Service today. History National parks were created before there was a National Park Service. President Ulysses S. Grant first set aside land for a “public park” in 1872 with the founding of Yellowstone. Yosemite, General Grant (now part of Kings Canyon), and Sequoia National Parks in California were created in 1890, and nine years later Mount Rainier National Park was set aside in Washington. With passage of the Antiquities Act in 1906, the President was granted authority to declare historic landmarks, historic and prehistoric structures, and sites of scientific interest as national monuments. -
3.6 Riverflow Issues
AFFECTED ENVIRONMENT & ENVIRONMENTAL CONSEQUENCES CHAPTER 3 3.6 RIVERFLOW ISSUES 3.6.1 INTRODUCTION This section considers the potential effects of interim surplus criteria on three types of releases from Glen Canyon Dam and Hoover Dam. The Glen Canyon Dam releases analyzed are those needed for restoration of beaches and habitat along the Colorado River between the Glen Canyon Dam and Lake Mead, and for a yet to be defined program of low steady summer flows to be provided for the study and recovery of endangered Colorado River fish, in years when releases from the dam are near the minimum. The Hoover Dam releases analyzed are the frequency of flood releases from the dam and the effect of flood flows along the river downstream of Hoover Dam. 3.6.2 BEACH/HABITAT-BUILDING FLOWS The construction and operation of Glen Canyon Dam has caused two major changes related to sediment resources downstream in Glen Canyon and Grand Canyon. The first is reduced sediment supply. Because the dam traps virtually all of the incoming sediment from the Upper Basin in Lake Powell, the Colorado River is now released from the dam as clear water. The second major change is the reduction in the high water zone from the level of pre-dam annual floods to the level of powerplant releases. Thus, the height of annual sediment deposition and erosion has been reduced. During the investigations leading to the preparation of the Operation of Glen Canyon Dam Final EIS (Reclamation, 1995b), the relationships between releases from the dam and downstream sedimentation processes were brought sharply into focus, and flow patterns designed to conserve sediment for building beaches and habitat (i.e., beach/habitat-building flow, or BHBF releases) were identified.
