This box is 20 ft long and 18 inch wide. The in and out runs are 3ft high, it is 4 ft at the highest point and 2 ft at the lowest. We just need to lam it and tag it up, then wait 4 snow. If you ride Monarch u WILL c it there. We are also building a S box for them, you can see the tail end of it in the left of this shot. I will upload a pic of the s box when it is farther along.
