our journey begins at the east entrance ofyellowstone national park, exploring the lake yellowstone. we continue tracking yellowstoneriver and catch our first glimpse of the parks' geothermal features in the mud volcano area. as we look north, we discover why the viewsof the upper and lower falls had such a dramatic impact on the park's creation. following the grand canyon of yellowstonewe head to the open plains of the lamar valley. at the northwest corner of wyoming, we understandwhy the park is a national treasure, starting with the mammoth hot springs. venturing southward exploring the geothermalbasins of the yellowstone crater, we arrive
at its most famous feature, old faithful,in time for a spectacular finale to our journey. with five entrances to yellowstone nationalpark, we approach from the east, following along the shoshone river in the wapiti valleyabout eighty kilometres from cody, wyoming. because of the weather restrictions, the eastentrance to the yellowstone park remains open only from may to november. on entering the park, there's a glimpse ofthe towering peaks of the absaroka range of the rocky mountains. yellowstone, which became the world's firstnational park in 1872, hosts over three million visitors a year.
access to the park from the east is made possibleby the sylvan pass, maintained to allow winter travel by snowmobile or snow coach. it was named after sylvan lake which restsalong the route. as we continue along the pass, we come toyellowstone lake, the largest body of water in the park. its basin is part of the massiveyellowstone crater carved from volcanic eruptions over 600,000 years ago. yellowstone offers a splendid habitat forover sixty species of large mammals. here we spot a small herd of elk. the parkhosts an estimated thirty thousand in total. the lake's northern tip is where it's fedand drained by yellowstone river.
a fishing bridge crosses at this meeting point- a spawning area for t native cut-throat trout. and nearby, is a popular recreational vehiclepark. visitors wanting less rustic accommodationstay at the historic lake hotel. originally built in the late 19th century,the hotel was restored to its 1920s grandeur in 1990. the yellowstone river is a main tributaryof the missouri river and drains nearly an eleven-hundred- kilometre stretch of the rockies. within the park, the river is used recreationallyfor flatboat fishing.
the words yellow stone were recorded by lewisand clark during their famous expedition, after meeting with the minnetaree indiansnear the river in 1805. north along the river, we enter the mud volcanoarea. these formations are created from a geo-excretionof iron and hydrogen sulphide, which results in a dark gray colour and rotten-egg smell. flowing north out of hayden valley, the firstsigns of rapids are present as the yellowstone river begins its descent toward the park'sgrand canyon. the river first cascades at the upper falls,dropping about thirty-three metres. spectacular viewing points along the trailson either side of the canyon make this one
of the favourite places in the park amongvisitors. and it's yet another example of how yellowstone'slandscape was shaped from volcanic events 600,000 years ago. the upper falls marks a junction where a hardlava flow met with a softer, altered flow. in 1871, dr. ferdinand hayden, whose namewas given to the valley, led a us geological survey into the unexplored yellowstone region.joining the expedition were photographer william henry jackson and artist thomas moran. their photographs and paintings of the fallscaptured the nation's attention and inspired congress to establish the national park ayear later.
the yellowstone river continues to flow anotherhalf kilometre before taking a much bigger plunge that will take it to the mouth of thegrand canyon. the lower falls, drops ninety-four metres,and is the tallest waterfall in the park - nearly twice the height of niagara falls. it's also the largest volume of falling waterin the rocky mountains. and this is the famous vantage point alongthe canyon that was immortalized in the famous painting by thomas moran, which now hangsin the white house. it was these majestic falls that were thesubject of the almost mythic accounts composed by prospectors, venturing into the montanaterritory in the mid 19th century. frontier
newspapers printed claims that the falls were"thousands of feet" high and referred to it as the "most sublime spot on earth". two scenic routes off grand loop road offerbreathtaking views of the canyon, such as point sublime on the south rim. the other viewpoints take visitors to theabsolute brink of the upper and lower falls, offering them a riveting encounter with thepowerful cascades. some 10,000 years after the volcanic eruptionsin yellowstone, lava flows filled the region. one of these was a canyon lava flow, leavinga thermal basin shaped from the hot steam and gases that altered and weakened the lava.
other flows blocked lakes and created overflowinglakes that further moulded the yellowstone canyon. the park contains several broad, open valleyssuch as the lamar valley in the park's northeast corner. packhorse treks are very popular for guidedcamping tours. organised trips can last as long as 10 days, as visitors venture intothe heart of yellowstone's tranquil wilderness. lamar valley and the river stretches for almostten kilometres from its confluence with the yellowstone river just below the grand canyonto its junction with the soda butte creek tributary.
a true treasure of yellowstone, the valleyis remarkable in its scenery. but it was also the stage for one of the mostsignificant wildlife conservation projects--the recovery of the american bison. in 1903 there were less than fifty bison inthe park. a century later, the population was nearly five thousand. the yellowstonepark bison herd is one of 4 in north america that are free roaming and genetically pure. twenty-seven kilometres north of the canyon,a small creek shoots off of the yellowstone river and flows south to the park's thirdnotable cascade, tower fall, which stands forty metres tall.
named for the volcanic formations that surroundit, the park offers a breathtaking view from an overlook that draws visitors in droves. flying northwest, we pass over the rooseveltlodge historic district. originally built in 1919 as an education centre,the lodge offers guests rustic accommodation and horseback tours, exploring the area'swildlife. the area was named in honour of presidentteddy roosevelt, who camped near the site prior to its construction. here we witness another popular tourist attraction,stagecoach rides. once the primary mode of transportation forguests, who traversed the park for days along
dusty roads, stagecoaches offer a nostalgicadventure through the sage covered fields of pleasant valley. we are fortunate to capture a rarely seenresident of yellowstone, the black bear. the park actually has a sizeable population,as opposed to the estimated mere three hundred grizzlies that take residence in the park. although this bear is seen in the open meadow,black bears are usually found in timber areas. in our journey across the northern valleysof yellowstone, we observe a playful bison. these animals are quite nomadic, migratinghigh to these grassy plateaus in the summer to mate.
they are vegetarians, grazing on the grasslandsin the meadows and foothills as well during the colder seasons. bison are the biggestof the park's animals, and it is believed that the yellowstone bison habitat is theonly one in america to have existed since prehistoric times. elk are high-elevation mammals and are moreoften seen in the early morning or late afternoon in the summers, grazing on the grasses ofthe meadows. in 1988 wildfires damaged thirty-six percentof the park. these areas eventually became a habitat forthe elk as lush vegetation developed. for this reason, they also graze in areas recentlylogged.
the elk bulls are symbolized by their beautifulantlers. the rack may have six to eight branches on each side and weigh more than thirteenkilos. by march or april of each year, the bull completely sheds its antlers, then beginsto re-grow them starting in may until august. elks are common around the entire park insummer. and nearby, the gardner river cuts throughthe rugged sheepeater canyon, named after the sheepeater indians who were believed touse these cliff edges to herd and trap game. today, a spectacular trail along the canyonbrings hikers to one of yellowstone's best-kept secrets, the osprey falls. nestled in the narrow gorge, the spray createdby the waterfall provides a welcome cooling-mist
for visitors on a hot summers day. the park sits on a plateau at an average heightof twenty-four hundred metres, bound by mountains that soar as high as thirty-three hundredmetres. often the plateau fills with clouds, settinga very enchanting tone for visitors. nestled between mt. everts and the mammotharea, about eight kilometres from the north entrance, is yellowstone park's headquarters,a series of red-roofed buildings constructed in the late 1800s and early 1900s. for most of its early existence as a nationalpark, yellowstone was operated by the us cavalry, with this area serving as an army post forthirty-two years.
the stone buildings house four hundred occupants. in 1918, the army turned over control of thepark to civilians, who have has maintained fort yellowstone as the park's headquartersever since. the historic army buildings now serve as officesand resident housing. additionally, there is a medical clinic andthe albricht museum, which chronicles a history of the park's residents. adjacent to the fort yellowstone districtlies a magical white hillside blanketed in calcium carbonate. this geothermal wonder of nature, the mammothhot springs, is a large complex of limestone
terraces, appearing in white, tan and cream-colouredvarieties. a circuit of boardwalks and stairs allow explorersto navigate through the impressive displays of step-like sedimentary rock. each of these formations exhibits individualcharacter, such as the now extinct liberty cap, a fourteen-metre cone formed from hotwater emanating from a single source. as heated water from the norris geyser basinmoves through a fault line and escapes the earth's surface through cracks and fissures,dissolved limestone is deposited onto the terraces. over eighteen hundred kilos of calciumcarbonate flow into mammoth each day. the yellow, orange and brown terraces gettheir colour from bacteria that are able to
grow in the waters. we exit the northwest region of yellowstoneand continue our journey moving south, back towards the crater rim. it is here that we'll explore a basin thatboasts the park's highest temperatures. the extreme thermal conditions of the norrisgeyser basin result from the junction of two major fault lines and the ring of the fracturezone of the yellowstone crater. for this reason, the basin boasts the hottest,most acidic and most dynamic thermal features in the park. clear pools become violently bubbly and muddy,even temporarily transforming into geysers.
within this basin, we see a hot spring withprismatic characteristics, developed from the pigmentation of the bacteria that growsin this mineral rich water. near the western entrance is the origin ofthe madison river at the confluence of gibbons and firehole rivers, overlooked by nationalpark mountain. this place is known as madison junction andlegend has it that this is the site where leaders of the 1870 washburn expedition firstconceived the idea of creating a national park whilst sat around a campfire. continuing south, we examine the lower geyserbasin, with thermal features that are scattered in small clusters, spread out mostly on openmeadows along the firehole river.
we concentrate on the firelake and the fountaingroups, known for its multi-coloured mud pots. the basin also delights spectators with itsfumaroles and geysers, as well as bubbling pools and hot springs. the white dome ejects water and steam througha six-meter high pinkish-white cone. the lower basin geyser has many areas of highactivity such as the firehole and hot lakes, which drain from a tributary of the fireholeriver. the aptly named steady geyser is the largestconstantly erupting geyser in yellowstone and the world. the fountain paint pot group is the most diversecluster of thermal features in the lower basin,
with hotsprings, mudpots, geysers and fumaroles.the clepsydra geyser, a name derived from the greek word for water clock, has four vents,spewing water in two different phases. clepsydra's "wild" phase can last three to six hours. the other notable feature of this group isthe fountain paint pots, which derive their name from their red, yellow and brown colours.in the spring, these mud pots are most active, when an abundant source of water from meltedsnow creates a dancing effect in the bubbles. during the warmer summer months, the mud getsdrier and thicker. in between the upper and lower geyser basinsis the appropriately named midway geyser basin, nicknamed "hell's half acre" by the writerrudyard kipling. this is excelsior geyser,
once the largest in the world, which releasestwenty-two million litres of water per day into firehole river. excelsior is flanked by the grand prismaticspring, the largest hot spring in the park and third largest in the world. the spring discharges over two thousand litresof water per minute. the colour varies at times depending on thepigment ratio of the bacteria growing in the water, as well as the water temperature. the deep blue colour is so intense due tothe high purity and depth of the water in the middle. the grand prismatic spring isyet another famous yellowstone subject of
artist thomas moran. moving along to the upper geysers, we focuson an isolated group called the black sand basin, highlighted by its colourful hot springssuch as emerald and rainbow pools. the basin got its name from the black volcanicglass that covers much of the area. another famous feature of the upper geysersis the most unusually shaped grotto geyser. the gusher formed around the stumps of deadpine trees, destroyed by an earthquake thousands of years ago. with a clear view of the old faithful geyser,the inn of the same name has operated as a hotel in the park since 1904.
constructed of locally grown pine, it is thelargest log hotel in the world. the foundation and the massive fireplace insidewere made from the volcanic stone that is dominant in the park. a short walk from the historic inn is theold faithful geyser. because of its predictability, it is quitepossibly the most calculable geothermal feature on the planet. thus, the cone-shaped geyseris also the most visited and anticipated attraction. like most visitors to the park, the famousus army expedition that named yellowstone in 1870 count old faithful as the first geyserthey set eyes on. thus, she was also the first in the park to receive a name.
the best indicator among locals of the nexteruption is to watch for the benches around old faithful to fill and overflow. old faithful begins each performance witha prologue of splashing and small jetting for a period of up to twenty minutes. thejetting usually grows over two to three steps before reaching its maximum height.ranging thirty-two to fifty-six meters in height, she shoots out between fourteen andthirty-two thousand litres of water. predictions of old faithful's next eruptionare based on the durations of its previous blast, which average two to four minutes.the intervals between eruptions average about ninety minutes, and times are estimated oneeruption in advance.
old faithful is indeed both a symbol of yellowstonepark and an american icon. a perfect place to end this journey.
