North end of unit 42 in CO info please&33 info

I'm curious as to how much public lands there are available in unit 42 especially the north end that borders unit 33 by rifle what is the terrain like in througout unit 42 and 33 just a general description for each direction of these areas would be fine just to get a feel for the areas since they are both new to our party this year and what types of roads are there as far as main travel routes go and what areas will have less four wheeler trails or access and where are some good areas to camp in 33 Thanks the Minnesota Gang
