...South Coal wash may be the easiest, but has some dugways that are narrow and might be spooky in slick conditions. I have a PDF of that motorized travel map somewhere - maybe I can figure out how to post it. All those routes have good scenery.
...I've also crossed Eagle near Horn Silver wash - the crossing was interesting, but not worth the boring drive on either side.
...That map is over 3 meg - I could shrink it but you probably could not see any detail. I cropped the map to what we're talking about.
...I assume you have encountered the 54" or narrower section of behind the reef road? That's a bummer. I would like to drive that. Little Wild Horse is a great drive - do that if you have not already.
FWIW that is the old map, they have a newer map that came out in ~06' that has far more detail and clarity than there older map. I know I've found it online before but if you would like a copy pm me your email addy.
I am trying to keep up w/ the conversation. Are you guys committed to one of the Coal Wash roads? I'd like to take that route but my Heep is practically stock. There are a few others w/ stock vehicles who might have to take an alternate route. And if we took a Coal Wash route, would we be able to make the E. Reef on the 1st day?
I have to sit this one out, I am on call at the hospital that weekend.
