Mammoth Hot Springs est un grand complexe de sources chaudes sur une colline de terrasses de travertin dans le parc national de Yellowstone. Le calcaire est la roche sous-jacente dominante à la place de la rhyolite, qui domine dans les autres grandes zones hydrothermales du parc. Cette région est l'un des meilleurs exemples au monde de sources chaudes de dépôt de travertin. C'est également l'une des zones hydrothermales les plus dynamiques du parc: ses caractéristiques changent constamment. Des terrasses inactives sous-tendent la majeure partie de cette zone, y compris l'hôtel et le centre d'accueil des visiteurs d'Albright. La température maximale de l'eau est de 163 ° F / 73 ° C. Pendant des centaines d'années, les habitants de Shoshone et de Bannock ont recueilli des minéraux provenant de la source chaude de Mammoth pour la peinture blanche. Ces minéraux contribuent aux belles structures de la terrasse, ainsi qu’à la chaleur, à un système de «plomberie» naturel, à l’eau et au calcaire. La source de chaleur volcanique pour les sources thermales de Mammoth reste un mystère. Les scientifiques ont proposé un certain nombre de sources, y compris la grande chambre magmatique sous-jacente à la caldera de Yellowstone, ou peut-être une source de chaleur plus petite plus proche de Mammoth. À Mammoth, un réseau de fractures et de fissures forme le système de plomberie permettant à l'eau chaude souterraine d'atteindre la surface. L'eau provient de la pluie et de la neige qui tombe sur les montagnes environnantes et s'infiltre profondément dans la terre où elle est chauffée. De petits tremblements de terre peuvent maintenir la plomberie ouverte. Le calcaire, déposé ici il y a des millions d'années lorsqu'une vaste mer recouvrait cette région, fournit l'ingrédient final. L'eau chaude avec du dioxyde de carbone dissous prépare une solution d'acide carbonique faible. Lorsque la solution monte à travers la roche, elle dissout le carbonate de calcium, le principal composé du calcaire. En surface, le carbonate de calcium se dépose sous forme de travertin, la roche qui forme les terrasses des Mammoth Hot Springs. Couleurs primaires: Les thermophiles (micro-organismes épris de chaleur) créent des tapisseries de couleurs où l'eau chaude circule entre les terrasses. Les thermophiles incolores et jaunes se développent dans les eaux les plus chaudes; Les thermophiles orange, marron et vert se développent dans des eaux plus froides. Les couleurs changent aussi avec les saisons. Sculpture vivante: Ces terrasses sont comme des sculptures vivantes, façonnées par le volume d'eau, la pente du sol et les objets se trouvant sur le chemin de l'eau. Ils changent constamment et parfois du jour au lendemain, mais l'activité globale de l'ensemble de la zone et le volume des rejets d'eau restent relativement constants. Ici, comme dans peu d’autres endroits de la planète, le roc se forme sous vos yeux. Terrasses inférieures: Vous pouvez accéder à ces terrasses depuis les trottoirs situés à leur base ou depuis Upper Terrace Drive. Certaines sections du trottoir sont accessibles aux fauteuils roulants; le reste de la région a des escaliers ou des pentes raides en raison du terrain. Upper Terrace Drive: L'entrée de Upper Terrace Drive se trouve à 3,2 km au sud du centre des visiteurs d'Albright sur la route Grand Loop. Cette route panoramique à sens unique serpente sur 2,4 km au sein de sources chaudes et de formations de travertin. Les caravanes, les autobus et les autocaravanes sont interdits sur l'allée en raison du nombre limité de places de stationnement et d'une chaussée étroite et sinueuse. Garez ces véhicules sur le terrain près de la route du Grand Loop, puis profitez des terrasses supérieures à pied. S'il vous plaît restez sur la route et les trottoirs.

Nice trail to get great views and see plenty of wildlife. Signs said trail only accessible with snowshoes or skis, but they were well traveled and hardpacked for easy walking. Mid February

Easy hike along board walks but spectacular

Went in mid-December...Great trail... some areas require snowshoes or skis... wear lots of layers and waterproof pants as well as waterproof boots...dress like you are going skiing... bring a hot drink in flask that will stay hot at least 9 hours...have fun, enjoy snow, and don’t break a leg or ankle...

We did just part of this trail system. There was a bull elk hanging out by the Minerva terrace with 2 cows. Pretty cool to be that close to a huge elk. He was right next to the boardwalk the whole time. There were lots of elk around Mammoth the day we were there. Interesting area.

A very popular spot so go early or late to avoid the big crowds. We parked at the parking lot at the entrance to the scenic drive (upper terraces) and started the boardwalk trail right there. There is an outhouse there and you'll avoid all the crowds down at the visitors center and shopping area. As others have said, walk the boardwalk (lower terraces) and drive the scenic drive (upper terraces). It is very interesting to see how the area evolves with sections that are active and still growing and sections that are no longer active and deteriorating.

Something different from the rest of the park, and I'd recommend it. Be prepared for the drive it's probably just under 2 hours from West Thumb, 1.5 hours from Old Faithful. Although, it always seems your stopped by wildlife or roadwork . . . plan plenty of time to get there, but it's worth it

The hot springs are incredible. What I didn't like it's the suggested walk pass car way. Not much to see and many cars driving past you on a small road.

A must see if you are visiting Yellowstone! Can drive through a portion of the park, but as usual need to get out and hit the boardwalks to really see everything.

Great views of the springs from a boardwalk and paved trail. Very manageable walk/hike for people of all skill levels.

We almost skipped this because we weren’t planning to head so far North in the park - I’m so glad we didn’t. The pictures on AllTrails don’t do it justice! It is another of the boardwalk “trails” in Yellowstone and it’s right off the road, so it was very trafficked. However, the hot springs and thermal features were so, so cool to see in person so definitely with dealing with the crowds. Another plus is that we saw three bears on our way to this part of the park, as opposed to the zero that we saw anywhere else during any part of our trip.

Boardwalk with stairs, through one of the most amazing natural thermal features in the world. Closeup views of thermophilic bacteria and mineral terraces. Views of the canyon below. Kid friendly, and of course it’s crowded.

Good starting point if your coming in the North Entrance. But compared to other geothermal features in the park, it’s pretty bland.
