I'm in the billings area too, lived here most of my life. I'm also part of the rimrock 4x4 club out of Billings. We are going out next sat. We leave the parking lot of the Laurel IGA at 8:00am. We are going up Clark fork canyon to the base of the switchbacks and hiking back to some frozen falls. This is mostly rocks and sand, only about a 2 on a scale of 1 -5. We will return by going to check out a section of a nearby trail that was washed out in the spring, and we are going to see if it's passable, then it will be unto a road over to Red Lodge... With lots of snow banks to get through. If you want to check out some local trails, you can look at my YouTube channel "pastorjohnmontana" ... From there you can see videos of many of the trails in our area. Hope you can make the trip, should be a lot of fun... And you will be only one of two or three Jks...
