you saw a cow!!! blue eye shine plus height, plus dumb stare and not moving. and yeah i see cows in wilderness type areas all the time, its called open range! thats why they have cattle guards on alot of mountain roads. i have never been to this mountain, but i have been all over colorado!
also some helpful info from google research:
i was looking all over for this info and finally concluded that; mountain lions have goldish green eyeshine and bears have red eyeshine,
dogs and coyotes are gold/greenish, deer are whitish, owls are red/orange, cows and horses are blue, sheep and goats are blue/green, bighorn sheep are sage green,
frogs are green, and spiders are silver.
humans dont have eyeshine, but red eye from a camera flash is only from an upclose and bright flash reflecting off the blood vessels in our eyes, but we dont have reflectors or Tapetum lucidum which helps animals see in the dark.
