I live in Northern Michigan. In the town there are a herd of elk in a large pen of many acres near my work. In the last two days they have really started bugling. I assume that this may coincide with them beginning to rut. If this is the case what are the odds that the same thing is happening in Colorado right now? I fly out friday to hunt on Saturday. It would be nice if they are bugling. How much do local conditions and areas affect the rut. Is the rut more influenced by global changes (length of day, temperature, altitude etc.)? Or by local conditions? I am hunting near Carbondale at about 7600 ft. Thanks again for any input.
