Death Valley Part 2- Guaranteed to make geologists salivate! (this means you rach,rennie and lachie)

So i don't know much about rocks, but after travelling in New Zealand and South America, I have a feeling that Death Valley is pornography for Geologists... mostly because my sister Rach and friend Rennie deem to be quite jealous about certain parts of my travels... And for the rest of us, they're pretty amazing rocks!!!
