Placing a prediction for Colorado/central rockys elk every year, batting .500 , I am.
With the September new moon @ the 20th , I'll wager early rutting activities with an earlier peak around the 4th of October and less vocal bulls by the end of muzzle loading season ~ 1st rifle.
The end of muzzleloader season this year is on September 17th. Where I hunt, the peak of the rut has always been before October 4th so a peak around the 4th would be late for us.
