Artist's Palette

Furnace Creek Visitor Center: "The striking colors splashed onto the rock at Artist's Palette were made by hot, mineral-rich waters bubbling up from below.
The magma-heated water met lava, ash, and lake sediments, changing the chemistry -- and the appearance -- of the rocks.
The greens and blues are chlorites; the pinks and purples are manganese oxides; and the reds and oranges are iron oxides."
