I just returned from three weeks on Colorado, started in Colorado Springs, finished in Grand Junction, hiked 121 miles according to my tracker, did not see an single elk. Hiked high and low, drove for hours, always looking. Spent a day in Pike National Forest, covered miles on a SxS, not even a single sign (note, the forest is mostly burnt). Saw lots of Mule deer in Utah new Zion NP but did not spy a single elk anywhere, near or far. Spent last summer in MT, elk were everywhere, by the hundreds. CO is supposed to be the most populated state, go figure! Although this was a family vacation, I was hoping to get some inside info for a possible DIY hunt, I have since scrapped that idea.
