have not been to barnes in a long time, hah but it is good riding if there is snow. another area to check out in corbin is to keep sledding past the barnes lake turn off, hit the 4 way and go east there. there is a bowl all the way into the back, about 1 km before you hit that bowl there is another to the south, sorta hard to find, just look for the valley going to the south. At the 4 way if you go west, i think it is a old sismic line you can ride that into the pipeline area. roughly 5km in on that, go up a avy shout and you will be at the top of barnes lake. so you could do a circle route.
another area before carbin is the pipeline, just head in there and you will find something pretty easy as there are trails and sleds everywhere
hope that helps
