Map of South Coast Slides and Names

A number of people have requested a small map of the slides and their names. I posted in 2014, and will post again here. This is the map that Don Harlan created by hand in January of 1971. I have a old xerox copy of that map which I scanned. The ori9ginal is no better than you see here, and I can’t improve on it. I warn again, no one could read Don’s handwriting, which is why he typed when he could. This is no exception. As far as I know, this is the only map in existenance of the slide namesake locations. If you find a different one that is more legible, please let me know.

  1. I saved this when you posted it a couple years ago. I can barely make out his handwriting. Do you know what WLSP at the bottom stands for?

  2. Thanks Kate that’s a map I don’t even have, my dad and my wife wrote long letters to each other and neither one could read each other’s handwriting.

  3. That’s funny, Mike. My mother was like that. I was one of the only one’s who could read her handwriting, so I will discipher Don’s.


  4. Was listening to a program on NPR last evening about the ground water situation in the Central Valley of California.

    The earth has sunk two feet & well-head concrete foundations are sticking up in the air all along the 400 mile length of the valley- indicating this level of drop.
    Aquifers are being depleted- causing the earth to sink-, farmers are digging wells deeper, residents cannot afford to dig half million dollar wells to keep up with the farmers. Almonds & pistachio trees are sucking up the water, four times faster than the lettuce used to.
    When the water is no longer available, the land will be worthless desert.

    The rain causes the rainy-season-slides, but the water is essential to life.

  5. Hello all, just a heads up on this next trio of storms slated to impact the central coast. The main difference with the next line up of lows/storms compared to the last run is that each storm will be progressively “stronger” instead of “weaker”! This means by the monday 1/23 storm, which is starting to look like a large moist occluded (arctic and subtropical origins) air mass could be one of the largest storms of the winter? The impacts of this third and final storm of this late january run could support thresholds (hydrologic or intrinsic) with soil weight-land slides- or cfs rates in rivers meeting criteria for big shifts in land and possibly higher creek/river flows than we saw last storm cycle and lateral bank erosion and channel shifts in major watersheds. We should know by Friday (1/20) afternoon what this last storm is going to turn into and def keep tabs on it!! Lastly the good news is high pressure and clear warmer weather looks to settle in mid next week through extended!??
    Cheers to very interesting winter, paul h

  6. I was amused by the “can’t read the writing” comment. I am Don’s niece. My father, Stan, my son, Adam, and I have been typing up Don’s diaries for years now, and, yes, they can be very difficult to read. I do have the entry he made when attending your wedding. Thank you so much for keeping up this blog. It has given me much pleasure and kept me informed over the years.

  7. We laughed about your comment, and decided his entry re our wedding was something along the lines of: “That crazy portegee is getting married again.”

  8. I have the whole packet that Don Harlan gave my father – his cousin, Walter Trotter years ago. There are two maps and the 10 page explanation of all the area’s mentioned on the map. Can make brief outline for you if you would like.
