Best Things to do in Yellowstone National Park (Part 1)
One of the greatest experiences in Yellowstone National Park is witnessing its geologic wonders. Topping the list are the hydrothermal features: hot springs, mudpots, fumaroles, and geysers -- particularly, Old Faithful. Well over 10,000 different hydrothermal features have been estimated to be active within the park. Even more incredible might be that over half of the world's active geysers are found here.
Every year, some 500-700 geysers are active. In 2011, it was determined that 1,283 geysers have been recorded as erupting in Yellowstone. This is truly incredible, when all of the rest of the world's geysers combined number less than 500. Hydrothermal features are extremely dynamic, changing throughout the day, across seasons, and over the years. This makes revisiting the different thermal basins so interesting. Besides seeing familiar sites, you can also see how those areas have changed since the last visit.
My name is Rob Decker and I’m a photographer and graphic artist with a single great passion for America’s National Parks! I’ve been to 52 of our 61 National Parks — and Yellowstone is one of my all-time favorites! I have explored most areas of the park — so I’m ready to help! So if this is your first time to the park, or your returning after many years, here are some of the best things to do in Yellowstone National Park! Yellowstone is huge...and this is the first of three posts describing what to do and what to see when you visit Yellowstone National Park. Read on to learn more about the southern part of the park.
Watch Old Faithful Geyser
Watching Old Faithful Geyser erupt is a Yellowstone National Park tradition. People from all over the world have journeyed here to watch this famous geyser. The park’s wildlife and scenery might be as well-known today, but it was the unique thermal features like Old Faithful Geyser that inspired the establishment of Yellowstone as the world’s first national park in 1872. Old Faithful is one of nearly 500 geysers in Yellowstone and one of six that park rangers currently predict. It is uncommon to be able to predict geyser eruptions with regularity, but Old Faithful has lived up to its name, only lengthening the time between eruptions by about 30 minutes in the last 30 years. Thermal features change constantly and it is possible Old Faithful may stop erupting someday. Geysers and other thermal features are evidence of ongoing volcanic activity beneath the surface and change is part of this natural system.
Check out Fishing Bridge
The original bridge was built in 1902. It was a rough-hewn corduroy log bridge with a slightly different alignment than the current bridge. The existing bridge was built in 1937. Fishing Bridge was historically a tremendously popular place to fish. Angling from the bridge was quite good, due to the fact that it was a major spawning area for cutthroat trout. However, because of the decline of the cutthroat population (in part, a result of this practice), the bridge was closed to fishing in 1973.
Visit Yellowstone Lake
Large volcanic eruptions have occurred in Yellowstone approximately every 600,000 years. The most recent of these erupted from two large vents, one near Old Faithful and one just north of Fishing Bridge. Ash from this huge explosion -- 1,000 times the size of Mount St. Helens -- has been found all across the continent. The magma chamber then collapsed, forming a large caldera filled partially by subsequent lava flows. Part of this caldera is the 136-square mile basin of Yellowstone Lake. The original lake was 200 feet. higher than the present-day lake, extending northward across Hayden Valley to the base of Mt. Washburn.
Explore the West Thumb of Yellowstone Lake
Members of the 1870 Washburn party noted that Yellowstone Lake was shaped like "a human hand with the fingers extended and spread apart as much as possible," with the large west bay representing the thumb. In 1878, however, the Hayden Survey used the name West Arm for the bay. West Bay was also used. Norris' maps of 1880 and 1881 used West Bay or Thumb. During the 1930s, park personnel attempted to change the name back to West Arm, but West Thumb remains the accepted name.
Explore the West Thumb Geyser Basin
West Thumb Geyser Basin, including Potts Basin to the north, is the largest geyser basin on the shores of Yellowstone Lake. The heat source of the hydrothermal features in this location is thought to be relatively close to the surface—only 10,000 feet down! The West Thumb of Yellowstone Lake was formed by a large volcanic explosion that occurred approximately 150,000 years ago. The resulting collapsed volcano later filled with water forming an extension of Yellowstone Lake. The West Thumb is about the same size as another famous volcanic caldera, Crater Lake in Oregon, but much smaller than the great Yellowstone Caldera. It is interesting to note that West Thumb is a caldera within a caldera. The hydrothermal features at West Thumb are found not only on the lake shore, but extend under the surface of the lake as well. Several underwater geysers were discovered in the early 1990s and can be seen as slick spots or slight bulges in the summer. During the winter, the underwater thermal features are visible as melt holes in the icy surface of the lake. The ice averages about three feet thick during the winter.
