Geology of the Yampa & Green River

Geology of the Yampa & Green Rivers

The Yampa River is a tributary of the Green River located in the western United States. The Yampa River is famous for being the last wild free flowing tributary of the Colorado River system. The geology of the Yampa and Green River basins is primarily composed of layered sedimentary rocks such as sandstone, limestone, and shale, which were deposited during the Paleozoic, Mesozoic and Cenozoic eras.
Geology of the Yampa and Green Rivers
The Yampa River originates in the Park Range of the Rocky Mountains outside of Steamboat Springs, Colorado and flows on a westward course through the Yampa River Canyon, which is cut into the sandstone and shale of the Mesa Verde Group. The Yampa River then turns north and flows through  Dinosaur National Monument, where it cuts an incredible canyon landscape composed of Weber Sandstone, Morgan Formation, Madison Limestone and several other geologic features.

The Green River, on the other hand, begins in the Wind River Mountains of Wyoming and flows south through the Green River Basin. Along its course, the Green River cuts through the rock layers of the Uinta Mountains. The most prominent formation the Green River cuts through is the Uinta Mountain group primarily the intense red rock that makes up the Uinta Mountain Group and the Lodore Formation. These two layers of rock are the predominant geologic timeline of the Gates of Lodore Canyon. The Green River then turns west and flows into the Uinta Basin, where it cuts through the rock layers of the Wasatch Formation and the Mancos Shale.

The Yampa and Green River join forces just east of the Utah and Colorado border in one of the most striking landscapes in the western United States, a place called Echo Park. Echo Park is at the heart of Dinosaur National Monument and a wonderful section of incredible scenery, natural and human history.

Both rivers are important for the ecosystem and human activities, The Yampa River is an important source of water for irrigation and recreation, and is home to a variety of fish and wildlife species. The Green River, on the other hand, is an important source of water for irrigation, hydroelectric power, and recreation, and is also home to a variety of fish and wildlife species.

Overall, the geology of the Yampa and Green River basins is characterized by layered sedimentary rocks that were deposited during the Paleozoic, Mesozoic and Cenozoic eras, and both rivers have shaped the landscape through erosion and deposition. The Yampa River flows through a narrow, steep-sided canyon, while the Green River flows through a variety of wide, flat valleys and deep rugged canyons. A Utah or Colorado white water river rafting adventure is a perfect way to see some of the most iconic geologic wonders of the Colorado River system.


5 Great Restaurants After Your Utah Rafting Trip

So you just came off an excursion down one of Utah’s gorgeous rivers. You’ve had camp meals for the past several days. Or maybe just a deli lunch on a day float. Maybe even just a granola bar and some trail mix. Yes, you may have been exposed to sun, wind, possibly even rain I could imagine. You’ve packed and unpacked a boat numerous times, even if it was just this morning and just this evening. Anyway you cut it, you’ve likely worked up an appetite – and not an appetite to do more work. You’re returning to civilization, and while that may be hard it certainly comes with some perks. Perks like near limitless meal options, and someone else preparing the food for you to boot. The only hard part of this equation is where to eat?

 

Dinosaur Brewhaus

If you’re coming out of Dinosaur National Monument after a 4 or 5 day trip on the Green River Gates of Lodore or Yampa River, Vernal Utah boasts several great spots to sate your hunger.

Raft, kayak, or tube this river (pick up your trash!) and enjoy the Taggart’s Grill at the take out. Taggart’s Grill offers exquisitely crafted sandwiches, soups, and pizzas. They’re in house desserts – like their carrot cake – are out of this world, and their beer selection isn’t too bad to boot. Just remember, no shirt, no shoes, no service.

 

 


Almost everything you need to Know about the Yampa River

Almost everything you need to Know about the Yampa River

To attempt to explain everything you need to know about the Yampa River through Dinosaur National Monument in one short blog is all but impossible but here are a few of the basics. The Yampa meanders from its headwaters near Steamboat, Colorado through town where teenagers float on tubes, into a narrow canyon with class V rapids where gripped kayakers test their skills, through flat desert until it reaches Deerlodge campground. This is the beginning of the Yampa Canyon and the start of 71 miles of some of the best white water rafting in the Western US. There are entire books written on the importance of the Yampa river to the environmental movement, natural history, and rafting community.

In the early 1900’s the dam craze took off across the United States. There was a belief vibrating through humanity that man could conquer nature, that enough technology had been developed power could be harnessed and controlled for the utility of human kind and there were very few movements to stop the development of public lands. It was in this mindset that the Echo Park Dam was proposed. If this dam would have been built it would have flooded the entire Yampa canyon we raft down today. The story is long, and best told through the misty eyes of a crusty river guide who sees their home flooding with the creation of the dam, but in short: an LA family came rafting down the Yampa and fell in love. They brought the story of the proposed Echo Park dam back to LA where David Brower and the Sierra Club learned of it. Through massive efforts people from a multitude of groups fought to save the Yampa. This became the first nationwide grass roots environmental movement. This makes the Yampa the last major undammed tributary of the Colorado river system. Today almost every soul who passes down the Yampa canyon expresses their gratitude for the Sierra Club helping to preserve the waterway.

Not only is the lack of dam on the Yampa historically significant, it creates an untampered environment for the creatures that call the eastern Utah desert home. Scientist study the animals, bugs, fish and plants in an attempt to see the effects that dams have on river ecosystems. In the 70’s scientist found that the Yampa Canyon was nesting some of north America’s last Paragon Falcons. They tagged and tracked the birds and helped ensure the young would hatch to help repopulate the endangered animals.  Today falcons can be seen throughout the river canyon in the summer months.

Beyond environmental history, astronomers study the night sky from Dinosaur National Monument as it is the darkest national monument in the country.  Its remote location protects it from the light and air pollution of human existence.

And Even before the River Rats and scientists called this place, home there are 500 years’ worth of Native Americans history, who thrived in the canyons, leaving us to marvel at what they left behind.

The Yampa River is one of the river most dynamic rivers in the country, changing with the natural flood stages of the Colorado snowpack eventually dwindling down to a mild stream as the snowpack disappears. This makes the river exciting to raft and different every time you launch rafts and boats from the put in.


White Water Rafting For Beginners

White Water Rafting for Beginners

White water rafting can be intimidating, especially if your only perspective is from the adventure documentary Congo: The Grand Inga Project. You might be thinking to yourself.  “These people are insane! I don’t want to die in crocodile infested waters, with beaches unsafe for camping, where literally everyone dies!”  Well not to worry. Not all white-water trips are the red bull version of a whitewater adventure. There a few levels of starting your rafting adventures ranging from a scenic float trip on the Green River below Flaming Gorge Dam to a four or five-day multi-day trip in Dinosaur National Monument on the Yampa River or Green River through the canyon Gates of Lodore.

The Scenic Float:

This trip is perfect for the beginners with young kids, people looking for a relaxing day out or someone unsure if white water rafting is for them. A scenic float typically involves a little bit of white water splashing in a beautiful place. They offer class I-II rapids, places for kids to swim in the water, a delicious lunch, and the option to use an inflatable kayak depending on the company you are booking through. It’s a great way to get a sense of what it’s like to float on a river raft trip. In Vernal, Utah Dinosaur River Expeditions is the only locally owned and operated outfitter we have a great day trip on the A-section of the Green River it is the ideal place for a scenic river float. It offers views of the beautiful Uinta mountains, a bit of geological and environmental history from your guides, and the potential to see a few bald eagles, great blue herons, mule deer and maybe a pronghorn antelope. This trip is a great activity if you are visiting the vernal area for a few days and want to spend a day on the water. https://dinosaurriverexpeditions.com/expedition/daily-trips-flaming-gorge-river-rafting/

The Mellow Multi Day:

Looking for more than a one day trip but you are still unsure about river trips with bigger rapids. We offer a great multi day option that can be just one night, or three, has class 2 and 3 rapids and will give you a great idea for what river camping is like, or glamping rather. A standard night on the river is going to include a campfire, a gourmet dinner complete with Dutch oven dessert, falling asleep to the sounds of the river, and a pancake or French-toast breakfast. This option is on the Utah section of the Green River from Flaming Gorge Dam to Brown’s Park. It’s a beautiful trip with class II rapids and lots of wildlife. The river tends to be much less populated on these lower sections of the river offering seclusion with your family and a chance to view Utah’s night sparkling sky. https://dinosaurriverexpeditions.com/expedition/green-river-flaming-gorge/

The Thrilling Four Day and Five Day:

If you tried the Splashy day trip and a mellow overnight and want to mash the two together, a thrilling four-day or five day trip is right up your ally. In Dinosaur National Monument, the Gates of Lodore on the Green River and the Yampa River are perfect multi day white water rafting adventures. They are classic white water adventures and will offer all the perks of a mellow overnight: great food, seclusion and wildlife with spicier rapids such as Warm Springs on the Yampa River or Hell’s Half Mile on the Green River through the Gates of Lodore. Your guides will know a lot about the area and be able to give you a fairly detailed history of the environment, and geology around you. If you already know you love camping and are a thrill seeker don’t be afraid to jump straight to either of these trips. They are  great trips for a first timer or experienced river rafter a like!

The Congo:

After a four day Lodore you are ready for the Congo. Just kidding. This is not a river for beginners in any sense, unless you are beginning the late stages of a professional kayaking career.

Nothing ruins a trip fast than a sunburn and an angry dehydration headache. Listen to your guides and have fun! The river is a great place to let yourself have a little fun and embrace your inner child. Your amazing guides will make it as safe and fun of an experience as possible.
