	Looking towards NW across Lavic Lake, rupture passing from lower right, stepping out toward upper left; NW end of the surface rupture is in the distance on the far side of Lavic Lake.
	Cracks on far side of wash; called 'en-echelon' breaks where they step sideways.
	Splaying of fractures viewed from above.
	Southeast of maximum displacement site. Here we see 3-4 meters o 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.
	Fractures crossing a wash.
	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 middl distance.
	View downward onto vehicle tracks crossing the fault at a high angle. One can see 2.5 to 3.5 meter right-lateral displacement of the tracks.
	Fracture running along hillside in low-relief topography with offset gullies and tracks.
	Ground view along surface rupture, showing the fracturing of the soil and how pieces have been pushed up within the fault zone.
	Subparallel breaks coalesce on face of hill (in shadow) and form a single rupture heading off to the upper left.
	Downward view onto gullies, gravel bar, and other laterally offset features. Here slip appears to be about 2 meters.
	Rupture cutting across the countryside in loose alluvium.
	Breaks cutting alluvium, nicely lit.
	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.
	Fracture cutting across the countryside.
	Fracture cutting across the countryside (left to right) such that fault scarp is lit up by the sun, appearing as a bold white line.
	'Mole track' at the max. slip site from the ground.
	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.
	Splayed fractures running through loose alluvium.
	'Apparent' vertical displacement and scarps caused by mainly lateral slip.
	Same as 21.
