Explore our planet through photography and imagery, including climate change and water all the way back to the 1800s when the USGS was surveying the country by horse and buggy.
Fault plane exposed at locality 23.
View of fault plane on hillside south of locality 15.
View south from locality 15.
Tire tracks at locality 22 offset on 4 main strands.
Offset tire track at locality 21.
View south along eastern fault trace toward locality 15 (in wash behind vehicle) and side-hill bench along fault.
Minor graben along eastern fault trace north of locality 15.
View along rupture at approximately localities 11 and 12.
Offset edge of wash at locality 8.
Offset minor channels within wash at locality 8.
Offset eroded tire track at locality 6.
Small offset drainage.
View along fault at approximately locality 3.
Offset tire tracks on south side of road at locality 1.
'Apparent' vertical displacement and scarps caused by mainly lateral slip.
Splayed fractures running through loose alluvium.
View towards south across Lavic Lake, with the surface rupture running from lower right to upper left. In the middle distance on the right is an ancient lava flow.
'Mole track' at the max. slip site from the ground.
Fracture cutting across the countryside (left to right) such that the fault scarp is lit up by the sun, appearing as a bold white line.
Fracture cutting across the countryside.
View downward onto site with maximum observed lateral displacement along the Lavic Lake fault. Here a vehicle track and dry creek bed are laterally offset by approx. 370-480 centimeters. The orientation of fractures here is nearly North-South. Compression locally across the fault pushed up a 'mole track' where the fault breaks the dirt road at the right side of the photo...
Breaks cutting alluvium, nicely lit.
Rupture cutting across the countryside in loose alluvium.
Downward view onto gullies, gravel bar, and other laterally offset features. Here slip appears to be about 2 meters.
Subparallel breaks coalesce on face of hill (in shadow) and form a single rupture heading off to the upper left.
Ground view along surface rupture, showing the fracturing of the soil and how pieces have been pushed up within the fault zone.
Fracture running along hillside in low-relief topography with offset gullies and tracks.
View downward onto vehicle tracks crossing the fault at a high angle. One can see 2.5 to 3.5 meeter right-lateral displacement of the tracks.
View right along the main rupture zone, and also visible is a subsidiary fracture from lower-right corner coalescing with the main break in the middle distance.
Fractures crossing a wash.
Southeast of maximum displacement site. Here we see 3-4 meters of right-lateral slip have offset a ridge and created a 'shutter' ridge blocking flow in the dry creek channel. The white vertical surface is the fault scarp.
Splaying of fractures viewed from above.
Cracks on far side of wash; called 'en-echelon' breaks where they step sideways.
This is a false-color-composite satellite image, Great Salt Lake, Sept 1999. Vegetation appears red.
The fault trends through a highway overpass (which did not fail), causing the guardrail to be offset ~2.8 m.
