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.

David Loope studied geology at Utah State and University of Wyoming, and is now a professor at University of Nebraska. Besides southern Utah, he has carried out field studies in the Nebraska Sand Hills, Mongolia, Argentina, and, most recently, in Jordan. Dr. Loope and his Nebraska colleagues Richard Kettler and Kerri Weber have been working together in the Monument since 2009. 

The presentation will last about an hour and is free. Call 435-644-1200 for additional information.
