We are going down to San Rafael for the weekend, and I wasn't sure if there are any caves that I should be made aware of. Thanks.

There are some small caves and big sinkholes in the area, but nothing I know of that seems very interesting for cavers.

Yep, huh is right. I assume capn_blasto's comment was just a troll. :lame:

So, Sinkhole Flat (which is pictured in your photo I assume) was named for potholes? :crazycobasa: Lots of other sinkholes thoughout the Swell in the Sindbad limestone.

The MK Tunnels in San Rafael Swell are pretty cool. If anyone is interested, I could post photos and location.

These pics are from a recent trip in early September. The tunnels are man-made holes drilled by the military when they were searching for an appropriate site for the NORAD headquarters. Sandstone lost out to the granite found near Colorado Springs.

I'm going down to the swell this weekend. Does anyone know if the MK tunnels are still open?

Yup, they're still open. I think DOGM is planning on closing them off this spring/summer sometime, but it may even happen later than that.

Oh, and be sure to stop by my Buckhorn Wash (http://www.geocaching.com/seek/cache_details.aspx?wp=GCNPRV) cache while you're there! Just don't hurt yourself coming back down. :lol8:

would one of you be willing to give me some exact coord, or directions to these tunnels. summit42 and I will be making a trip down that direction for his bday at the end of the month, and I';d love to visit them prior to closing.

About a mile north of Castle Dale, turn off Highway 10 at these coordinates:

Hahah...I think those are only about 2' diameter, but that's not the only problem. Those drill holes are vertical. :ride: :scared:

I think the light you see at the end of the tunnel is actually a reflection off the water in the bottom of the hole.

That being the case, if Summit bikes down this he will forever be hardcore in my mind. :haha:

It's looking up from one of the tunnels towards the surface. This test hole is only about 10" wide.
