There are pockets of both. North of Curlew out of town along the river is whitetail generally, east of town heading up Boulder Creek in mainly whitetail with a mix right on top and more and more mule deer as you head down the east side. About halfway down the pass turns back into whitetail again. Just out of Curlew to the NW you have Vulcon Mountain that is mainly mule deer but there are whitetail on it as well. Heading out of town to the west towards Chesaw you have a lot of private fields that are loaded with mule deer and whitetail. Around Boneaparte Lake you get into mostly mule deer unless you are right in the creek bottoms that are mostly private and then once again back into the whitetail. If you take the cutoff toward Waconda instead of Chesaw you will see a 50/50 mix but mostly private. Look up the hills you see the mulies look into the creek bottoms you see the whitetail. Head south of Curlew toward Republic you can cut up Lundimow Meadows for mostly whitetail unless you wind around toward Job Corp and there are a few pockets of mule deer up higher. Thicker timber. Continue south to republic you can hit hwy 20. Head toward Sherman and get up high and you will find higher concentrations of just mule deer but I have seen big whitetail right on top. Head toward Tanasket and you will have whitetail in the bottoms but you end up in more sage brush and rocky country that becomes primarily mule deer. From living in Curlew for sometime I learned that it is really a transition point in my opinion. You can really decide what you want to hunt from there and go in any direction and find it.
