Thanks for the info given. Just a few more questions

How large is the Sag? Would a pair of waders or knee boots be sufficient in crossing the river in some areas? Or is a raft basically needed? Also, whatare the general patterns of the caribou. Since their calving grounds are in the north, and they eventually go south, do they tend to go east/west much, or have a pattern of which direction they normally come from in relation to the Road?

Thanks again for the info!
