I hiked White Mountain on Monday (6/24) in bad weather. Around 13,000 a horned sheep was on the trail going down while I was going up. He/she spotted me and continued to approach me and slowly veered off about fifty feet away. I don't know if they are aggressive but I slightly slowed my pace. The sheep had a red tag on its right ear and what looked like a yellowish collar attached at the neck. I thought the weather made this hike interesting enough but this encounter helped make it memorable.
Barcroft has a history of doing high altitude research. I recall reading the sheep are raised to determine the effects of altitude on their embryos. I've never seen them out grazing - just in their pen near the buidlings.
