Gator- According to the DWR in 2009 Beaver had 800 elk on the unit and Monroe had 1050, and Beaver is a much bigger unit. I have spent time on both units and from my perspective, from Manning meadows down through upper and lower box, the concentration of elk is way higher than anywhere I have found on the Beaver unit and I have covered most of it. Lower concentrations of elk and rugged terrain I think are some of the reasons Beaver holds some giants.
I am sitting on 14 elk res points and both of these units are ones I am considering applying for a muzzy tag on.
I think Beaver might have a better top end potential but Monroe would be an awesome hunt with lots of bulls and a easier time harvesting one. Just throwing that out so if someone reads this and thinks Beaver will be one of those hunts with elk running everywhere. Not so from my experience at least. Me and my dad got our butts handed to us last year on Beaver and we ended up turning his muzzy tag back in.
