Geocache Description:

East Side Hopland road, you'll be pullin off just past the little bridge and keep your eyes out cuz "BenchMarks the spot!"
The fault runs from Tindall Ranch Road with the fault following East side road to this cache. So as your on your way to this cache, you will be driving along the Fault Line just after you make th eturn at the bridge.

Last cache of the Ukiah Valley Mayacma Fault line series and from here the fault ventures SouthEast through Hopland virtually splitting Zone IIIa and IIIb. Mendocino County may be divided into four areas which have similar bedrock and soil characteristics, ground rupture potential, ground stability and flooding characteristics. These areas
of similar geotechnical characteristics are called “Geotechnical Hazard Zones.”

The boundaries of the Geotechnical Hazard Zones cannot be precisely drawn. Each zone and related hazards are dependant upon the faults and land makeup, such as landslide potential, liquefaction, and active fault lines. The Zones are identified by Zone 1- Coastal (San Andreas Fault Zone), Zone II- (Mayacma fault Zone), Zone IIIa West of Mayacma fault to coastal(Central County Zone - Coastal Belt), Zone IIIb- East of Mayacma fault to Potter valley(Central County Zone - Eastern Belt), Zone IV From Potter Valley to Lake county(North East County Zone). All of these Zones carry different Seismic potential, All are capable of ground shaking, surface faulting & ground failure, with Zone I (coastal) being the most active with the San Andreas fault system and also capable of seismic induced waves AKA Tsunami's. Zone II (Mayacma Fault) is rated not only for a M7 Earthquake but also is rated high for landslide potential. Evidence of soil instability can be observed widely throughout the southern county.
Zone III has been divided into two subzones. The Maacama Fault Zone is the approximate boundary between the two subzones. Zone IIIa is the Coastal Belt of the "Franciscan Assemblage".
The Coastal Belt of IIIa consists of younger and generally more stable rock units than the older rocks of
the Eastern Belt which is known as Zone IIIb. There are many small faults in these Zones.. Most of these are generally considered to be inactive. Earthquake risk is lower in Zones III and IV than in Zones I and II, but landslides can occur causing minor earth movements.
Zone IV The northeast portion of Mendocino County is furthest removed from known active and potentially active faults. Only inactive faults are known in this area.
Surface rupture is not expected and the level of ground shaking from distant active faults will be less than the western and southern areas of the county closer to the San Andreas and Rogers Creek Faults.

I have images to include in some of these Fault line series caches, just need to figure a way to transer the file type so can include them in ths page description.

Also may be further Fault line series, as there are 2 other locations accesible of which the Fault runs right through, I hope to create 7 Fault caches...Hope you enjoyed the series and as always~

CACHE HARD and CACHE ON!
