Wednesday, January 9, 2019 – Chasing Color; Mining Boulder Opal in Australia
During their year-long “walkabout”, Geologists Dick and Mary Pat Weber visited most of the major opal mining districts of Australia. Their favorite area was the boulder opal deposits in the channel country of Queensland. Miners live under primitive and hazardous conditions in a remote area of the Outback, where there are more snakes, lizards and kangaroos than people.
Unique to the region, this opal is found in massive ironstone concretions of Cretaceous age. Through the generosity of their friends at Broken River Mining, learn how this material is mined and processed in order to bring the world’s most beautiful opal to market.
MINERALS, MICROBES, AND MARS
Time: 2:30 p.m.
Location: Geology 3656
Lecture by Dr. Aaron Celestian
Celestian collaborates with JPL scientists in a search for signs of ancient life preserved in minerals on Earth. Using non-destructive analytical methods, they measure biosignatures (like beta-carotene) in crystals that are thousands or even millions of years old. Their findings will help assess data from NASA missions to Mars and the icy moons of Saturn and Jupiter, places that may harbor life. For more info visit: http://www.meteorites.ucla.edu
2018 Fee Free Days on Federal Public Lands
Here are the 2018 fee free days offered for recreation sites under the management of the National Park Service and the U.S. Forest Service. While many parks, facilities and services associated with these agencies are free, some require a fee. Recreation fees, authorized by the Federal Lands Recreation Enhancement Act, enable federal land management agencies to reinvest in the management of various recreation sites.
2018 Fee Free Days

$1,000 Reward – Death Valley National Park
Fossil Thieves stole several fossilized footprints, which had been left in a lakebed by mammals and birds, were missing. Now, Ryan F. Mandelbaum reports for Gizmodo, the National Park Service is asking for the public’s help in identifying a group of backpackers who may have information on the ancient tracks. In a statement, the National Park Service released the photos of three men who might have witnessed the crime or have knowledge about the disappearance of the footprints. Investigators are offering an award of up to $1000 “for information leading to the identification, arrest, and conviction of those responsible,” the statement reads. According to Mandelbaum, investigators are planning to interview visitors who frequented the Park at the time of theft, in the hopes that someone will be able to provide valuable clues.
Destroying—or pilfering—the property of national parks is prohibited by law. “It’s illegal to collect fossils, rocks, or anything else in National Parks,” Park Superintendent Mike Reynolds said in a statement about the fossil thefts. “The purpose of National Parks is to conserve the landscape and everything it contains for the next generation. I ask that visitors come and enjoy all there is to see, and to leave it unimpaired for others to enjoy.”
The National Park Service has asked anyone with information about the stolen fossils to call the Investigative Services Branch at 1-888-653-0009.
