I have some information on the slide history, geological formation in the area, and plant restoration, etc. that I want to share, but I have saved it all in iBooks, which refuses to cooperate. I will try those pieces of the puzzle when I sort out the technical difficulties. In the mean time, here are photos of Gray Slip this month. One on 10/8 and another on 10/22 that show the spring. I have arbitrarily titled it Spring #1. There is another (#2) down next to the highway. Of course, there has been no rain since the digging here uncovered this spring.
Gray Slip, Oct. 2018

Looks like that can of worms could cause a replay at Grey Slip if el Nino hits us this winter with lots of rain…
