Site workers,

in follow-up to last the class tour where I tried to explain some geology, here is an encounter with the real with some real geology via a geological map of the santa paula area. download the pdf from this link and look for the orange lense shape just above and to the left of the center of the map along the river and that is where the ranch is. it is just opposite two water streams that come together at the river bank on the other side. if you blow it up you will see that the yellow areas are major and still active landslides in the last few thousand years. The arrows show direction of movement. the ranch houses, barns and road are just barely visable as little blackish purple shapes in the middle of the orange lense along the river. if you follow the roadway back from the houses toward the gate you can see the area that dropped a foot in the 2005 rains, which I showed you. And, check out the Oak Ridge Fault running along the center of the river bed!! Deep End indeed!

**remember, your post is due to the seminar by the end of the day today.

in class tomorrow everyone will speak about their site work project plans under development. after the lunch and discussion you may go off on your own on the ranch or I will offer the following which you may choose to do: a screening of Robert Smithson's film of the making of Spiral Jetty; a tour of the rest of the ranch facilities, guest house, variable space (steel barn) which is available to us as presentation & work space for our show, then, my studio & the future home of the collection of orphaned collections.
