NORTH SALT LAKE — Ten days after a massive landslide destroyed a home, damaged a tennis club and temporarily forced the evacuation of more than two dozen homes, families remain on edge each time another storm threatens.


How many of your knew that the eastern border of Utah has a kink in it? For those of you that did know of the tiny shift, do you know the history behind it?

Utah’s boundaries are not defined by landforms such as mountain divides or rivers. Surveyors mapped Utah’s boundaries using transit and compass, chronometer and astronomical readings, previous surveys, and interviews with residents. The boundaries were intended to run parallel to lines of latitude and longitude.

One of the many landslide events in the last few days was a slide in the Eaglepointe subdivision in Salt Lake City in Utah.  The development of this landslide was brilliantly caught on a time-lapse video by KUTV reported Holly Menino and 2News photographer Mike Stephen:


Homeowners in a mountainside community north of Salt Lake City feared a cracked ridgeline above their property would send a landslide crashing below. They alerted city officials, who hired crews that began to raze the slope but couldn’t prevent a rock and debris from breaking away and smashing into a home.


The views in Utah go on for days, years, and centuries. Good thing we’ve got all of these beautiful geology photos to share with you! Have a wonderful evening, geo friends.

Evacuated families aren’t the only ones affected by North Salt Lake’s landslide that destroyed a house one week ago.


“The final failure is unpredictable,” he said of Tuesday’s slide. But, he added, a large crack in the ground opened at the crown of the slide a week before it let loose.


While many people may very much remember the 1983 Thistle Landslide, perhaps some of our newer geo friends to Utah are not familiar with the history surrounding it. Our Deputy Director Kimm Harty helps revisit the events of the slide in this KSL interview—check it out.

There are still a handful of houses stuck in water and time in Thistle, though they stopped being homes 31 years ago.


One of our geologists here at the Utah Geological Survey, Adam McKean, talks about the geological makeup of the hill in North Salt Lake that makes it prone to sliding.

Years before one home crumbled in North Salt Lake, the developer behind the project was given the approval by the city to build it.


As we find ourselves in another hot Utah summer, some of you may be wondering where the coolest spot in Utah is. Among all the cool places in Utah, the coolest by far is Peter Sinks. High in the Bear River Range in Cache County, Peter Sinks is frequently the coldest place in the United States in wintertime, even colder than anywhere in Alaska. Peter Sinks holds the second-place record—less than half a degree shy of the all-time record at Rogers Pass, Montana—for coldest recorded temperature in the contiguous United States at -69.3°F set on February 1, 1985.
