Caravan as usual- meet up at Hass Clubhouse parking lot.

We will park bear the Grizzly Peak Stables

We have to be very quiet so as to not scare the horses. When we arrive, get your computers set up, and wait outside the gate

I have included the basal Siesta Valley limestone on a map for each of you. We will observe the limestone bed from outside the Stables

Please be extra careful parking at the GP Stables.
