Spike Camp, I find your conclusion questionable as if there aren't elk calves within 20 miles of where you are finding bear scat with elk hair in it as it sounds like you are near winter range. There calving areas aren't that far away from you especially on big snow years. In my area elk calving is often near the top of draws at the sage brush/aspen ecotone within sight of the lowest winter range. The exact location of where the calf is dropped is not really that important since cow/calves are mobile day one and bears are highly mobile foragers. We can blame any number of factors on the Eagle county situation, but there appears to be ample research showing bear calf predation is significant from NM to Yellowstone. I doubt CO is the exception. "Ftguides" provided a link to a NM study summary in post 30 and a short internet search will show multiple studies in the Yellowstone area. If my recollection serves me, even Bugle magazine acknowledged a Montana study indicating bears as the most significant predator of elk calves until September despite the human hunter mantra of wolves wolves wolves.
I also question CPWs usual blame of human encroachment. As previously noted with the Estes Park elk, and even hunted elk in my area will bask in open alpine all summer within site of one of the busiest OHV congested passes, til September. So I am not ready to embrace humans everywhere is changing elk populations. It might change there seasonal behavior, but those cows aren't thinking about holding off on having a calf because there are too many mountain bikers.
imo.
