The Paints Pots site is located a couple of miles from Marble Canyon on the 93 and you can actually take a trail from the Canyon to the Paint Pots instead of driving. 
It’s a short 30 minut walk to the pots themselves, through forest then a small plain and a river crossing.
The First Nations tribes of this area collected ochre from the Paint Pots for important ceremonies. The yellow ochre was cleaned, kneaded with water into walnut sized balls, then flattened into cakes and baked. The red powder was mixed with fish oil or animal grease to paint their bodies, tipis, clothing or pictures on the rocks. 
The paint pots themselves are formed by the accumulation of iron oxide around three cold mineral springs. The greenish colour of the largest pot is the result of the mixing of fresh water from a small creek, which empties into the largest pool.
There are information boards dotted along the trail telling you about the history of the area. Well worth visiting.
