Yellowstone National Park is known for a multitude of different landmarks across the area that attract visitors from not all around the country, but from across the world. On this page, all of the old stereographs were found from Geology of National Parks, as well as the descriptions of the landmarks.
Old Faithful Geyser

One of the most famous parts of Yellowstone, this geyser erupts every 40 to 100 minutes, each lasting between 2 to 5 minutes in length. The spray ranges in height between 100 and 200 feet, with steam that rises even higher. Other popular geysers include Economic Geyser, Grotto Spring, and Riverside Geyser.
Grand Geyser Basin

Known as the Upper Geyser Basin thermal springs area today, it includes both Grand and Giant geysers. Although not as famous as Old Faithful, colonies of thermophilic microbial mats are growing on deposits. This growth adds to the precipitation you can see in the picture. All of the rocks in the Yellowstone caldera region consist of siliceous igneous rock, which is the basalt and rhyolite.
Giant Geyser

Giant Geyser is located in the Grand Geyser Basin and has one of the largest geyser eruptions in all of Yellowstone, with a cone of 12 feet high that consists of sinter (primarily quartz, opal, and clay materials) and a steam eruption lasting up to one hour. Many people are not able to ever see the geyser erupt because it only occurs every 6 to 14 days.
Punch Bowl Spring

This boiling spring is located in the Upper Geyser Basin and is around 12 feet wide and a whopping 30 feet deep. Other hot springs in Yellowstone include Angel Terrace, Pulpit Terrace, Mammoth Hot Springs, Minerva Terrace, Cleopatra Terrace, and Fishing Cone.
Kepler Falls

These falls are located at the upstream end of a gorge that is carved into a “Quaternary-age volcanic flows by the Firehole River” (Geology of National Parks). The water from the river is quite warm for the area and drains most of main the caldera region. Other falls in Yellowstone include Lower Falls, Upper Falls, and Gibbon Falls.
Obsidian Cliff

This cliff is made out of obsidian that forms when rapidly cooling lava has a low volatile content of water and carbon dioxide, and is an excellent rock used for various different kinds of tools. In the times where indigenous tribes lived in this area, this cliff was a prime source of obsidian because it can be easily chipped off. In the cliff, you are able to see a column jointing of two different lava flows; the lower part being early Quaternary lava flow.
Grand View Overlook

This overlook is on the western side of Yellowstone National Park. The canyon is “cut into early Quaternary volcanic rock” formed in the first enormous caldera eruption (Geology of National Parks). The ridge in the back left of the picture is the rim on the north side of the caldera. In the canyon you are able to see altered volcanic rocks, specifically rhyolite, in colors of yellow, orange, red, and brown.
