34.59264 -118.21508 236.80 km 3.6 3.0 - 4.5 Moderate-Low Offset channel. Correlation with Sieh uncertain. Offset otherwise well defined. Heavy erosion around fault zone makes reconstruction difficult.

Sieh (1978)

Offset (m) Error (m) Quality Rating Comments
2.9 +/-0.5 Fair/Good Two gullies. Separately, geometries give reasonable doubts as to validity of measurements. Taken together, they are Fair/Good. Bouquet Canyon thrust fault merges with San Andreas here and North Branch occurs to N. Geologically very complex.
