No, Johnny is not Dead. He Just went home... 
He's not much of a hike from parking, but it may be one frustrating
search to find him. Nonetheless, he knows Ulumay can be one burning
ring of fire in the Summer months, so be careful...
I'm going to say this cache is handicap/ wheelchair friendly
since its either on cut grass or within a reasonable distance from
it. However, I don't know how often its maintained so I'm listing
it as a 1.5 terrain difficulty.
