Skeptics in the Jeep: Anza-Borrego Mud Caves

Block out your entire day for this trip to the amazing "mud caves" in the Anza-Borrego desert. Prepare for lots of climbing, squeezing, and underground exploration.

There is a bit of background info on the caves here: http://www.desertusa.com/anza_borrego/Mud_Caves.html

The mud caves of Arroyo Tapiado in Anza-Borrego are the paths carved by underground rivers that flow beneath the badlands when rain soaks through the ground. Despite their name, they're bone dry. They twist a lot, but often have a flat, walkable surface.


We're going to enter about four different caves. Two are easily accessible for anyone, and two require squeezing into extremely tight spaces. If you are claustrophobic, generously statured, or mobility challenged you will have trouble and may not be able to enter these at all.


Bring a lunch, snacks, and all the water you can drink. There are no services along the way. We will eat lunch inside one of the caves. Other gear: a flashlight or headlamp. A change of clothes is highly recommended, as you will get very dirty and dusty. Optional: tough gloves and kneepads for crawling.


We want to carpool to minimize the number of vehicles, as it's a lot of driving. The road is accessible to most vehicles, but I would not bring a nice car on it. If you don't have at least a modest SUV I recommend riding with someone else. We'll have enough seats for everyone who wants to go.


TO ATTEND: Send a text message to me (Brian Dunning) at[masked] that includes:

1. Your name
2. How many are in your party
3. Where you will meet us (San Clemente or Escondido, see below)
4. Whether you're bringing a vehicle and how many seats you have available for passengers.


Everyone riding in someone else's car, please bring $20 gas money, which will be evenly distributed among the drivers.


Note that the times are EARLY!! Please be on time. People coming from north may prefer the San Clemente meetup; people coming from south or inland may prefer the Escondido meetup. Plan to be gone all day.
