Not sure what part of 53 you are planning on hunting but by the 4th season there should be snow in the higher elevations and possibly Kebler Pass will be closed. I hunted elk in unit 53 usually during the 1st season up on the top of Minnesota Creek in the raven, pines, and flatirons. This is public land that borders the West Elk Wilderness. That area will be pretty much snowed in by the 4th season. Depending on snow, You still may be able to get into the lower part above Minnesota Res. or around Beaver Res. There is also some access into the West Elks from Crawford. If there is alot of snow then you are looking at alot of private land and landowners to get permission or pay to hunt. I never hunted that low so don't have any info - coyote has much better info on the lower areas and most likely knows land owners. I am not sure that I gave you any info that is of use but also hope this is helpful.
