Dissolution of subsurface salt caused the collapse of the Salt Valley anticline, forming vertical fractures in the Jurassic-age Entrada Sandstone. Weathering along the fractures has produced the spectacular fins, towers, and arches in the Devils Garden section of Arches National Park.
“Spot the Rock” is back this week with a riddle! What Utah-“rock” is rarer than diamonds, and more valuable than gold?
Check for updates next week to see the answer! Like us on FACEBOOK or follow us on TWITTER to participate!
UPDATE: Answer revealed
Last week’s “Spot the Rock” was definitely one for our rock hounding friends. And everyone guessed right! Red Beryl is found in Utah, is rarer than diamond, and more valuable than gold.
The gemstone has several different names: red beryl, red emerald, or bixbite. Originally, the mineral was named bixbite, but now red beryl is the most accepted designation. Red beryl is estimated to be worth 1,000 times more than gold and is so rare that one red beryl crystal is found for every 150,000 diamonds.

We’re getting further into our wildfire season as summer heats up. Fires can start from both lightning and human causes, but did you know that rockfalls sometimes cause wildfires too? Check out our “Glad You Asked” article on what ignition source started Utah’s July 2012 Lighthouse Fire in Range Creek, Emery County.

The Utah Geological Survey (UGS) has released a publication containing 10 geologic-hazard maps for an area of western Salt Lake Valley that includes portions of the rapidly developing cities of Herriman, West Jordan, and South Jordan. The maps address hazards associated with earthquakes, landslides, flooding, debris flows, indoor radon, shallow groundwater, rock fall, shallow bedrock, and problem soil and rock (collapsible and expansive soils). The maps present a comprehensive hazard assessment and were prepared by compiling scientific and field data.

Eroded fragments of a dark ironstone layer contrast sharply against the pale-orange Jurassic-age Navajo Sandstone at Snow Canyon State Park. In places, the iron- and manganese-rich ironstone forms a resistant cap at the top of sandstone columns or pillars called hoodoos.
