Although a 2003 geotechnical report warned of the potential for landslides at Eaglepointe Estates in North Salt Lake, a 2013 supplemental study made no mention of the clay bedrock flagged for attention in the first and that one geologist called “a notorious bad boy” for instability.
The recent 6 M earthquake in Napa, California, can serve as a large-earthquake preparedness reminder for us Utahans. Utah is earthquake country, and the Wasatch Front is capable of producing large earthquakes. We can’t predict when or where an earthquake will happen, but we can prepare to the best of our abilities. This article has a great video about what you can do to prepare, and supplies you should have on hand.

The destruction witnessed in Northern California following a 6.0 magnitude earthquake should be a wake up call to citizens here in Utah. Our state could be next.

Dave Shearer sees the evidence of water levels dropping in the Great Salt Lake every time a boat has to be taken out of its slip at the Great Salt Lake Marina.
Another weekend gone by, and September on the horizon! Who got out into some cool geology this last weekend? Here’s an article for your Monday morning. While we cannot always avoid natural hazards and disasters, we can prepare to the best of our abilities. Check out this read for tips on reducing landslide risks around your home.

At the beginning of this month, a landslide in North Salt Lake destroyed one home and caused 27 others to be evacuated. People are rightly concerned about protecting their homes from disasters such as this. When things like this happen, we are all reminded that Utah is not immune to natural disasters. While we would drive ourselves crazy if we thought about the possibility of landslides and earthquakes every day, it is important to not live in complete denial either. We need to understand the risks and know what we can do to protect our homes against potential damage as best we can.
How about another round of “Spot the Rock”? Who can tell us what mineral the yellow arrow points to in the image?
UPDATE: Answer Revealed
It is SELENITE! For those who guessed, Gypsum, you are technically correct. Though this crystal pictured, Selenite, is a specific type of Gypsum.
This selenite crystal was found in the the mud of a canal bank and U.S. Magnesium near the south shore of Great Salt Lake. Selenite is the name given to the crystalline variety of the mineral gypsum (CaSO4·2H2O). Gypsum is a common evaporative mineral. While gypsum is commonly mined for use in drywall (what interior surface of most building walls), the crystaline form of selenite makes it difficult to process and thus undesirable for use in drywall.

Water levels at the Great Salt Lake are just a couple of feet above a record low set in 1963, and state geologists say it’s likely the lake will continue to evaporate.

Colorado/Utah –Ben Otoo and Nicole Ridgwell are spending the summer living a dream as they scramble and climb among the remains of the long dead. These young paleontologists are photographing and mapping the world famous deposit of ancient bones at Dinosaur National Monument. Their work is part of a multi-institutional effort to bring together the vast historical and scientific information about this great dinosaur quarry and ultimately make it available on-line to both scientists andthe public. With over 1500 dinosaur bones to document, and each bone needing multiple photographs to show all the anatomical details, plus converting several large historic quarry maps with drawings of thousands of bones needing into electronic files, it is a busy, but satisfying season.
