ColorChallenge - Monday Yellow

Well, today is Monday Yellow in ColorChallenge, so here is a picture of a yellow machine-on-wheels thing I found parked between Mosquito Peak and Treasurevault Mountain:

Here's a shot of Treasurevault from the north slopes of Mosquito. The yellow machine thing was down in that saddle:

These peaks are in the Mosquito Range between Leadville and Fairplay, Colorado.

P.S. Happy Monday the 13th! I'm sure Garfield the cat isn't getting out of his bed today.
