Day 4 – Anza-Borrego / Geology Trip

After being able to sleep in Tuesday morning, we headed to Fish Creek Wash and Split Mtn. where we spent the whole day into the early evening. The weather forecast was for high winds throughout the day & we experienced the high winds the entire day. We followed the wash back 15 miles or more making stops along the way looking at folds, mudflow & debris flow deposits.

I can’t pass up an opportunity to take a group picture along the way.

As we headed out at dusk, we neared the entrance on our way out, it was nearly dark and difficult to see the trial with the winds. Shortly after getting back on the highway, a huge dust storm came up & at times we had zero visibility … but all is well & we made it back to the Church for a wonderful spaghetti dinner.

I can hardy imagine what our adventure will be tomorrow.
