Big Water Dinosaur Festival 2013

Dinosaurs were significant tourists, back in the day. Some enjoyed the area so much, they decided to stay. A few of them were even known to throw their weight around! The Grand Staircase-Escalante National Monument (GSENM) has provided a treasure trove of dinosaur discoveries. Of the 39 new dinosaur discoveries worldwide, nine have come from the GSENM!

Geologic map of the Johnson Lakes quadrangle, Kane County, Utah, and Coconino County, Arizona,

By: Janice M. Hayden

The Johnson Lakes quadrangle includes parts of the Chocolate (Shinarump) and Vermilion Cliff steps of the Grand Staircase in the southwest part of Grand Staircase-Escalante National Monument. Reddish-brown Lower Jurassic strata of the Vermilion Cliffs dominate the map area. Overall, strata dip gently to the northwest. They are cut by the Paunsaugunt fault at the east edge of the map area, and by several minor, mostly down-to-the-west normal faults. A variety of surficial deposits locally conceal bedrock, including broad alluvial and eolian surfaces deeply incised by modern arroyos. “Picture stone” from the Shinarump Conglomerate Member of the Chinle Formation is quarried locally.

This CD contains geographic information system (GIS) files in ESRI file geodatabase and shapefile formats. Also included are two plates-the geologic map at 1:24,000 and the explanation sheet-both in PDF format. The latest version of Adobe Reader is required to view the PDF files. Specialized GIS software is required to use the GIS files.

This CD contains a 29-page report conducted by undergraduate researchers at Utah State University during 2010 and 2011 under the direction of Dr. James P. Evans. It includes data collected from hot springs in northern Utah and southeastern Idaho, including location, temperature, acidity, salinity, cation concentrations, and maximum reservoir temperature estimates acquired through the application of several cation geothermometers.

Sausageleaf talinum finds suitable habitat in sand and spherical concretions eroded from the lower part of the Jurassic-aged Navajo Sandstone. The concretions (about half an inch in diameter) formed when iron-oxide minerals precipitated out of ground water that flowed through the sandstone.

The narrow defile of Round Valley Draw exposes layers of ancient petrified dunes of the Jurassic-age Navajo Sandstone. This is one of numerous slot canyons in Utah’s canyon country formed by the scouring action of infrequent but powerful flood waters.

Special Presentation on July 16 “Microbes, Mars & Moqui Marbles”

sunews.net

Bureau of Land Management has rescheduled the presentation “Microbes, Mars & Moqui Marbles” on Tuesday, July 16. The program is a special Grand Staircase-Escalante National Monument (GSENM) Walks and Talks Lecture Series presentation to be held at the BLM Kanab Visitor Center, located at 745 East Hwy 89, in Kanab, Utah.

Beginning at 7 p.m., Dr. David Loope will reveal new insights into how microbes affect geology. Based on his recent research on the Navajo Sandstone within GSENM, Dr. Loope will explain how microbes, that have lived just below Earth’s surface for at least three billion years play an important part in the development of Moqui Marbles on Earth, as well as other planets, including Mars.

DISCOVERY OF DINO SKULLS IN GRAND-STAIRCASE WILL HAVE 'HUGE IMPACT'

sltrib.com

The skulls of Utah’s prehistoric lizards keep rolling out of the country’s largest national monument with the two newest ones so unusual that when unveiled this week, their discovery will have a global impact.

That was the message during last week’s lecture from paleontologist Scott Sampson, author, research curator for the Utah Museum of Natural History and host of the children’s science program “Dinosaur Train” on PBS.

Although the names of the new species of horned dinosaurs will not be announced until Wednesday at the museum in Salt Lake City, Sampson said their significance lies in helping scientists determine that horned dinosaurs living at the same time in different areas of the continent evolved differently.

“It [the discovery] will have a huge impact,” Sampson said last week at a public lecture at the Kanab visitor center of the Grand Staircase-Escalante National Monument.

His findings will be published Wednesday in PLoS, an online scientific journal.

One complete skull made from pieces of several skulls will be unveiled, along with a replica of the other.
