Wheat Thin is located on the east face of Elephant Rock. From the Elephant Rock parking area hike on the trail towards the formation. The trail follows a fence part of the way which marks the private property line. When you get to the base of detached boulders (not part of main formation), head up the class 3 friction slabs for about 20 or 30 feet to a small ledge right before the wall steepens up. You should see a crack/flake system above the ledge. The crack starts out diagonally upward and to the left and cuts back right higher above. This is your route.
The route climbs the east face of Elephant rock in one pitch. One can scramble (class 3) from the top of the route to the formation's summit (located near the Elephant's head).
Climb up the juggy face holds until you reach the flake/crack diagonalling up and left. Follow the flake as it makes a turn up and right further up. Protection opportunities are abundant - mostly small to medium cams. Follow the crack up on face holds as it eventually vanishes. In its place you now have a wide off-width crack on your left for protection (large pro, #5 Friend etc. or run it out to the top).
From the top of the route move left and down behind a large flake. Locate a pair of rap anchors at the top of the Rye Crisp (5.8) route. Rap with two ropes.
Note that there's probably a "walk off" option on Elephant but it probably requires crossing some private land nearby (the formation sits at the edge of the park).
A well rounded rack - small to medium pieces (mostly cams) for the lower 2/3rds of the route; a large piece or two (like a #5 Friend) for the offwidth crack near top.
