We’re celebrating #EarthScienceWeek this week! The Utah Geological Survey hosts hands-on activities for school groups (usually 4th and 5th graders) during October. Here, students join Utah State Paleontologist James Kirkland, and geophysicist Hobie Willis in the paleontology prep lab where they examine dinosaur and ice age fossils while learning about geologic history. Stay tuned with our daily updates on our Earth Science Week happenings!

Joint Evening Meeting with Association of Environmental Geologists (AEG), Utah Geological Association (UGA), Utah Geological Survey (UGS)
“Geologic Remapping of the Warm Springs Fault”
presented by Adam McKean, Mapping Geologist with the UGS

The Warm Springs fault of the Wasatch fault zone is a down-to-the-west normal fault, bounding the western portion of the Salt Lake salient. Recent geologic remapping of the Salt Lake City North 7.5-minute quadrangle has provided us an opportunity to revisit the Warm Springs fault and its place within Salt Lake and Davis Counties. A draft map of the quadrangle and evidences for the Warm Springs fault location will be presented at the meeting with opportunities for open discussion, questions, and feedback. We invite the geologic and geologic engineering community and interested parties to attend the event and take part in this public comment period.

For this #tbt we’re looking at Mount St. Helens and the beginning of its 2004 eruption. While it wasn’t to the magnitude of its notable 1980 eruption, the 2004-08 eruption resulted in a remarkably rapid, though nearly steady, rate of dome growth. Check out the U.S. Geological Survey (USGS)‘s youtube video for a time lapse of the dome on Mount St. Helens! #throwbackthursday

Cities in southern Utah are still cleaning up the mess from a flash flood that fell in the area on Saturday. The storm brought down a lot of water, but it also brought down a lot of dirt.


Good morning, everyone! At the request of NASA, Tom Chidsey (geologist for the UGS) supplied a list of Utah-related names for use during the current operations of the Mars Curiosity rover mission. As the rover begins its journey up the slopes of Mt. Sharp, NASA scientists are starting to use names from the Utah list to reference specific Martian rock outcrops. Names like Upheaval Dome and Shinarump have already been used. Follow THIS LINK to see amazing photos and commentary. Out of this world!

Here is a very interesting read for your afternoon. Have humans created the next chapter in Earth’s geologic history through our relationship and interactions with our environment? Check it out!


If you know how to read it, the face of a cliff can be as compelling as the latest bestselling novel. Each layer of rock is a chapter in Earth’s history, telling stories of birth and death, winners and losers, that help scientists understand the evolution of the planet over the past 4.6 billion years.
