Perhaps a dumb question but I had this question in my head last fall but never got around to asking about it, just remembered. I was in BLM / national forest (very west side of CO) and came across two loose horses with no halter or anything on them. I never got super close so no idea if they had a brand or such. But it got me wondering at the time if they were purposely loose and grazing (do ranchers do that with horses like cattle on big areas of unfenced land?), if they were horses that got loose from somewhere, or if they were wild horses? I didn't see any signs posted at any road junctions looking for stray horses. Basically wondering in hindsight the likelihood they were horses that got loose and if someone was looking for them.
