Sorry we can't tell you much about this cabin, but I'm sure if it could talk, it would have many a story to tell!
BYOP This cache is at approx 8,465 feet and should be accessible by most normal modes of transportation when you are thinking of jeeps, OHV, 4-wheelers, motorcycles, snowmachines, bicycles, horses, and even walking! I wouldn't take my low clearance car though -- any probably not even our full size dodge pickup although if I told my husband he couldn't get it up here, he would!!! 
The cache MAY be accessible in the winter (via snowmachine of course), as it is not on the ground, so we'll be interested to see if anyone logs it in the winter!
