I (Shirley) found this mark in good condition with friends along the Lanfair road. Everyone had gone away from where I thought this mark was, so I put the laptop onto the center console and walked right to where I thought I saw it. Yup. There is was, right next to a flowering Joshua Tree. Way Cool to be able to holler out that I had found it!

Recovered in good shape.
