Unique geothermal features where hot springs deposit iron-rich minerals, creating reddish-brown formations resembling molten chocolate. These iron-oxide deposits are formed as the hot, mineral-laden water flows out and cools, precipitating the iron and other minerals. They were first documented by members of the Hayden Geological Survey of 1871, led by geologist Ferdinand V. Hayden.

Agate is a microcrystalline variety of quartz, chiefly chalcedony, cryptocrystalline form of silica. Although agates may be found in various kinds of rock, they are classically associated with volcanic rocks but can be common in certain metamorphic rocks. Most agates occur as nodules in volcanic rocks or ancient lavas where they represent cavities originally produced by the disengagement of volatiles in the molten mass which were then filled, wholly by siliceous matter deposited in regular layers upon the walls. Cathedral Valley, Capitol Reef National Park, Utah.
