The Climax Mine on the Fremont Pass, 11,318 ft (3,450 m), is quite an operation with an interesting history. As the sign reads, molybdenum is used to harden steel. If you ever had a bicycle with a chromoly frame, you were riding on a molybdenum mix.
Laurie was wearing similar colors to the molybdenum ore cars on display in the outdoor museum across the road from the mine. The colors inspired her to do the molybdenum mambo. You can see a gif of the molybdenum mambo at: https://photoofthedayetc.wordpress.com/2017/09/25/the-molybdenum-mambo/
