Норрис Геисер Басин

Басен гејзира Норис је најтоплија и најпроменљивија термална област у Јелоустону. Истражићемо многе карактеристике које бисте видели када бисте ходали стазама дужине 2 1/4 миље (3,6 км). Откријте локацију највишег активног гејзира на свету, живописних топлих извора и микроскопског живота у једном од најекстремнијих окружења на земљи.

Гибон Фаллс

Гибон Фаллс пада 84 стопе (0,3 м) преко остатка обода калдере Јелоустон. Калдера је настала масивном вулканском ерупцијом пре отприлике 640.000 година. Брзо заустављање на нашој вожњи доње петље, ово је одлична прилика за тренутак фотографије.

4

Олд Фаитхфул

Олд Фаитхфул се налази у базену Горњег гејзира у Јелоустону у југозападном делу парка. Подручје за гледање гејзира је најприступачније и најпријатније за посетиоце у парку са клупама за седење, великим паркингом и ренџер станицом која прати време, висину и дужину ерупције како би предвидела следећу ерупцију.

5

Фоунтаин Паинт Пот

Дуж стазе Фоунтаин Паинт Пот ћете видети различите хидротермалне карактеристике које су израз још увек активног вулкана Јелоустона. У оквиру овог геолошког система представљена је свака врста термичке карактеристике. Могу се груписати у две опште категорије – оне са великом количином воде (врући извори и гејзири) и оне са ограниченом количином воде (муљовине и фумароле). Упркос структурним сличностима, не постоје две потпуно исте карактеристике.

6

Гранд Присматиц Спринг

Гранд Присматиц Спринг се налази у басену гејзира Мидвеј. Одликује се као највећи топли извор у парку. Има око 370 стопа (112,8 м) у пречнику и дубок је преко 121 стопа (37 м). Опис овог извора од стране ловца на крзна Озборна Расела из 1839. такође га чини најранијим описаним термалним обележјем у Јелоустону који се дефинитивно може идентификовати.

7

Језеро Јелоустон

Смештено на 7.733 стопа (2.357 м) надморске висине, Јелоустонско језеро је највеће језеро на високој надморској висини (изнад 7.000 стопа /2.134 м) у Северној Америци. Дугачак је отприлике 20 миља (32,2 км) и широк 14 миља (22,5 км), са 141 миља (227 км) обале и површином од 132 квадратних миља (342 км2). Језеро Јелоустон се потпуно замрзне сваке зиме крајем децембра или почетком јануара, а дебљина леда варира од неколико инча до више од два стопа. Језеро се обично одмрзне крајем маја или почетком јуна. Језеро Јелоустон остаје хладно током целе године, са просечном температуром воде од 41°Ф (5°Ц). Због изузетно хладне воде пливање се не препоручује. Процењује се да је време преживљавања само 20 до 30 минута у води на овој температури.

Иелловстоне Гејзири - Подручје блатног вулкана

Сам Јелоустон је вулкан, а једна од његових најспектакуларнијих ерупција догодила се пре 640.000 година. Током ерупције, земљиште се срушило и оставило велику депресију у земљи - Јелоустонску калдеру. Ова калдера испуњена лавом тече стотинама и хиљадама година стварајући вулкански плато који чини већи део централног дела парка. Овде на вулкану Муд налазите се близу једне од купола које се поново опорављају. Брда која видите источно одавде обухватају Соур Цреек Доме. Ресургент куполе су области активне деформације тла, где се земљиште помера горе или доле са флуктуацијом коморе магме испод. Научници пажљиво прате ове куполе ради информација о текућој вулканској активности. Није изненађујуће да се многи гејзири, топли извори, блато и фумароле у парку такође налазе у близини или унутар калдере.

9

Велики кањон Јелоустона

Велики кањон реке Јелоустон изражава сложену геолошку историју парка у драматичним бојама и облицима. Облаци паре обележавају хидротермалне карактеристике у зидовима кањона. Горњи и Доњи водопади реке Јелоустон доприносе величини јединственог природног блага.

10

Хаиден Валлеи

Хаиден Валлеи је велика подалпска долина у Националном парку Јелоустон која се простире на реци Јелоустон између водопада Јелоустон и језера Јелоустон. Дно долине дуж реке је древно језерско корито из времена када је језеро Јелоустон било много веће.

Firehole Canyon Drive

Firehole Canyon Drive is a 2-mile, one-way road off the Grand Loop south of Madison. The drive has a waterfall overlook and swimming area.

12

Norris Geyser Basin

Norris Geyser Basin is the hottest and most changeable thermal area in Yellowstone. We will explore many of the features you would see if you walked the 2 1/4 miles (3.6 km) of trails. Discover the location of the world's tallest active geyser, colorful hot springs, and microscopic life in one of the most extreme environments on earth.

13

Gibbon Falls

Gibbon Falls drops 84 feet (0.3 m) over a remnant of the Yellowstone caldera rim. The caldera was created by a massive volcanic eruption approximately 640,000 years ago. A quick stop on our drive of the lower loop, this is a great opportunity for a photo moment.

14

Old Faithful

Old Faithful is located in Yellowstone’s Upper Geyser Basin in the southwest section of the park. The geyser-viewing area is the most accessible and visitor-friendly in the park with bench seating, a large parking lot, and a ranger station that tracks the time, height and length of an eruption to predict the next eruption.

15

Fountain Paint Pot

Along Fountain Paint Pot Trail you will see various hydrothermal features that are expressions of Yellowstone’s still active volcano. Within this geologic system, each type of thermal feature is represented. They can be grouped into two general categories—those with a great deal of water (hot springs and geysers) and those with limited water (mudpots and fumaroles). Despite their structural similarities, no two features are exactly alike.

16

Grand Prismatic Spring

Grand Prismatic Spring is located in the Midway Geyser Basin. It has the distinction of being the park's largest hot spring. It measures approximately 370 feet (112.8 m) in diameter and is over 121 feet (37 m ) deep. A description of this spring by fur trapper Osborne Russell in 1839 also makes it the earliest described thermal feature in Yellowstone that is definitely identifiable.

17

Yellowstone Lake

Situated at 7,733 feet (2,357 m) above sea level, Yellowstone Lake is the largest high elevation lake (above 7,000 feet / 2,134 m) in North America. It is roughly 20 miles (32.2 km) long and 14 miles (22.5 km) wide, with 141 miles (227 km) of shoreline and a surface area of 132 square miles (342 km2). Yellowstone Lake freezes over completely every winter in late December or early January, with ice thicknesses varying from a few inches to more than two feet. The lake usually thaws in late May or early June. Yellowstone Lake remains cold year-round, with an average water temperature of 41°F (5°C). Because of the extremely cold water, swimming is not recommended. Survival time is estimated to be only 20 to 30 minutes in water at this temperature.

18

Yellowstone Geysers - Mud Volcano Area

Yellowstone itself is a volcano, and one of its most spectacular eruptions occurred 640,000 years ago. During the eruption, the land collapsed and left a large depression in the earth—the Yellowstone Caldera. This caldera filled with lava flows over hundreds and thousands of years creating the volcanic plateau that comprises much of the central part of the park. Here at Mud Volcano you are close to one of the resurgent domes. The hills you see east of here comprise Sour Creek Dome. Resurgent domes are areas of active ground deformation, where the land moves up or down with the fluctuation of the magma chamber below. Scientists monitor these domes closely for information about ongoing volcanic activity. Not surprisingly, many of the park’s geysers, hot springs, mudpots, and fumaroles are also found near or within the caldera.

19

Grand Canyon of the Yellowstone

The Grand Canyon of the Yellowstone River expresses the park's complex geologic history in dramatic colors and shapes. Puffs of steam mark hydrothermal features in the canyon's walls. The Upper and Lower Falls of the Yellowstone River add to the grandeur of the unique natural treasure.

20

Hayden Valley

Hayden Valley is a large, sub-alpine valley in Yellowstone National Park straddling the Yellowstone River between Yellowstone Falls and Yellowstone Lake. The valley floor along the river is an ancient lake bed from a time when Yellowstone Lake was much larger.
