This Earthcache is hidden along Orinda's partially graveled De La Veaga Loop Trail, which is a moderately difficult hike with lot's of uphill, but that also rewards visitors with incredible and expansive views of the bay. During Spring (When I originally hiked this area) the grass is lush green and the wildflowers are plentiful! Make sure you bring plenty of water and are in good physical condition before attempting. Note that you'll need to leave pups at home for this one, as dogs aren't allowed on this trail.
A landslide, also known as a landslip, is a geological phenomenon that includes a wide range of ground movements, such as rockfalls, deep failure of slopes and shallow debris flows. Landslides can occur in offshore, coastal and onshore environments. Although the action of gravity is the primary driving force for a landslide to occur, there are other contributing factors affecting the original slope stability. Typically, pre-conditional factors build up specific sub-surface conditions that make the area/slope prone to failure, whereas the actual landslide often requires a trigger before being released.
There are many different types of landslides. They are as follows:
Look to the South/West from the posted coords (opposite side of the trail from the transmission tower.) to see a good sized landslide in front of you.
To log this Earthcache, send me an email with the following information. Please do not post the answers in your log.
1. Just Another Scar in the Earth - GC9PNP1
2. Compared to the image above, what kind of landslide would you consider this?
3. Guestimate how wide the large landslide appears to go across the hillside.
4. Choose a signifigant part of the landslide and guestimate how far down that section of soil has slid so far.
5. There is a smaller (thinner?) landslide above and to the right of the main one. Describe the direction this smaller landslide runs along the hillside.
