This is one old tree! It's in the forest near "General Sherman" (see next photo) and is over 2000 years old.

General Sherman is 83 meters tall and seems like it's nearly as thick!
A small dike offset right laterally. On the trail to Pear Lake about 100 - 200 m from the camp sites. Tape open 10 cm and pointing north. Note how this fault isn't extremely straight. How would it's geometry affect slip along it?
Point 419, looking East. Note the dramatic contrast in color and fracture density between the fault zone and the surrounding rock.
Looking south from Point 419 at a portion of the amazing view of the Great Western Divide.
Point 421, Looking West. Steve taking field notes for scale.
Dike in wall of fault zone. At this locality, we observed slickenlines on the dike surface that plunge about 18 degrees to the east. At the narrowest portion behind Steve, the fault zone trough is 66 cm wide.
Near point 431. In Table Meadows looking west towards the ampitheater wall. Steve for scale.
Pear Lake is several kilometers behind the background. This was part of our daily commute from the end of the fault zone back to camp.
From point B1 looking up to Steve at survey point 435.
Matt at camp with his duct tape sandals constructed only from a box of quaker oatmeal and duct tape with grass for cushioning. They were commissioned by a renegade marmot who stole Matt's camp shoes.
Matt in a meadow in the saddle above Pear Lake after a hard day at work.
Exfoliation and wildflowers on the far side of the saddle above Pear Lake.
The wall of the Ampitheater, looking west.
Point 100A/G4 - G9 are on the top of the ridge on the right side of the frame.
Another view of the wall of the Ampitheater.
Sunset on the way back to camp. I think the highest point is Alta Peak above Pear Lake.
Point 489, looking south across a fault zone trough. Steve for scale. The dike he is sitting beneath was offset about 11 meters left-laterally.
Note how the prominent regional jointing on the left side of the image is oblique to the strike of the fault zone (which cuts across the image from left to right).
The lake about 30 meters to the west was a fantastic spot to watch the fish jump!
Looking west towards point 492. The lake is one of the "twin lakes" below the "fingers" which are up the hill on the left side of the image. On the right side, you can see the shallow-dipping dikes on the "island" between the two lakes.
View from the end of the world, near the "Big Dike" (see next photo). Looking N20E.
Note how the meanders of the big stream seem to lie on aplitic material (white) as does the lake in the lower left. It possibly fractures easier than the darker material. We mapped a dike that runs by the lone tree above the right hand side of the meanders. It continues uphill all the way to the lake barely visible in the center of the frame. We mapped another dike that runs from that lake along the bench to the right (higher up) and off the frame to the right (near Table Meadows).
The "Big Dike" at the End of the World. It's about 2.3 m thick, but CAN'T be traced any farther than this point right here on the north edge of the fault zone trough. About 20 m west of the Big Dike is a series of 3 dikes that all reveal ~14 m of left-lateral separation, but when we look in the appropriate spot for this dike, we can't find it!
Gorgeous Lupine downhill from 100A/G4.
The two troughs above Pear Lake can be seen in the upper-left of the image. Behind them is the cliff above Emerald Lake, the top of which is cut off in the very upper-left.
There is evidence for about 9 m left-lateral separation in several markers east of this point.
Trough of G7 looking N48E with Matt for scale.
The aplite body of 101A - G7 is on the right side of the image. Look how this trough keeps on going and seems to reach out towards the other side of the valley. There is another fault zone nearly parallel to the Pear Lake fault zone on saddle on the far side of the valley.
