Tule Springs Fossil Beds National Monument

Following meetings in regards to development in North Las Vegas, the Protectors of Tule Springs was founded in 2006 and successfully preserved 22,650 acres of federal land eight years later.  The area contains fossils of Columbian mammoths, ground sloths, American lions, ancient camels, dire wolves, sabre-toothed cats, bison, and three ancient species of horse ranging from 7,000- to 250,000-years-old.  There are plans to open a National Park Service (NPS) visitor center at the end of Aliante Parkway.

Highlights

Upper Las Vegas Wash, natural bridge, trash cleanup

Must-Do Activity

The actual Tule Springs are a desert oasis contained within Floyd Lamb Park, operated by the City of Las Vegas.  The Bureau of Land Management formerly controlled the acreage that became the National Monument and it was heavily impacted by garbage dumping, off-road driving, and shooting.  Your “must-do activity” here is to remove some trash.  The Protectors of Tule Springs have hosted several cleanup events.

Best Trail

There are no trails within the National Monument yet, but there are two access points to Upper Las Vegas Wash from Durango Drive and Aliante Parkway.  The wash contains Joshua trees and several patches of the rare Las Vegas bear poppy, and provides habitat for threatened desert tortoises, burrowing owls, and kit foxes.

Hike the Upper Las Vegas Wash about a half-mile east from the end of Durango Drive and look for a natural bridge carved in the soft mudstone wall. 

Peak Season

Winter when snow dusts the top of the Sheep Range and Las Vegas Range of mountains.

Florissant Fossil Beds National Monument

Overview

Like John Day Fossil Beds in Oregon, this area in central Colorado protects a geologically significant window into the past.  Here the fossils are 34-million years old, buried by volcanic debris and lake sediments, with species that do not look that different from plants and animals we see today. 

Highlights

Museum, Ponderosa Loop, Petrified Forest Loop, Big Stump, Hornbek Homestead

Must-Do Activity

A variety of butterflies, birds, leaves, and flowers are nicely displayed in the visitor center.  Our favorite was the bloom of Florissantia speirii, an extinct member of the cocoa family that grew at this site when the climate was much warmer and wetter.  After exploring the museum, head outside on the wheelchair-accessible Ponderosa Loop or hike some of the monument’s 14 miles of trails.

Best Trail

Take a walk on the Ponderosa or Petrified Forest Loops to see excavated stumps of massive redwood trees, fossilized in place with beautifully colored minerals replacing the original organic compounds.  You can even see annual growth rings preserved in the petrified wood.  If you have not experienced the massive dimensions of coast redwoods in California, these stumps will make you want to visit those living trees in person.

On your walk through the ponderosa pine forest, you may spot an Abert’s squirrel, a species known for its long ear tufts.  Also watch for elk.

Peak Season

Summer due to high elevation

Hagerman Fossil Beds National Monument

Overview

More than 3.5-million years ago, this section of southern Idaho was on a floodplain of a giant lake.  Lush grasslands and forests attracted camels, llamas, mastodons, zebra-like horses, and a variety of birds.  Their fossils were not discovered until 1928, on the steep bluffs on the west bank of the Snake River, now Lower Salmon Falls Reservoir.

Highlights

Museum, film, Snake River Overlook, Oregon Trail Overlook

Must-Do Activity

Numerous mammal fossils from the Pliocene Epoch are on display at the National Park Service visitor center, located on the main drag in the small town of Hagerman, Idaho.  Scenic overlooks of the Snake River and Oregon Trail are located further south, but there is no public access to the fossil beds.

Best Trail

The 3-mile long Emigrant Trail parallels the Oregon National Historic Trail, which has wagon ruts accessible from both the Snake River Overlook and Oregon Trail Overlook (where there is also a half-mile interpretive trail).

Interstate 84 passes directly over Malad Gorge State Park, north of Hagerman, Idaho.  Take the freeway exit and walk to the canyon rim to see the beautiful waterfall you missed from the bridge.

Fees

None for Hagerman Fossil Beds National Monument, but there is a day-use fee at Malad Gorge State Park.

Road Conditions

The main access roads are paved.  There is a one-lane bridge crossing the Snake River off Highway 30 that was closed during our visit so we took the Gridley Island Bridge instead.

Camping

There are places to camp along many sections of the Snake River, but not within the National Monument.

Fossil Butte National Monument

Wyoming

Managed by National Park Service

Established 1972

8,198 acres

Website: nps.gov/fobu

Overview

Exactly 100 years after the creation of Yellowstone National Park, another Wyoming site was added to the National Park Service (NPS) system in 1972: Fossil Butte National Monument.  It is dedicated to 50-million-year-old fossils found in an ancient subtropical lakebed, including plants (like palms and ferns) and animals (like turtles and lemurs).

Highlights

NPS museum, film, Fossil Lake Trail, Historic Quarry Trail

Must-Do Activity

Even 50-million years ago it was windy in Wyoming!  The excellent preservation of the fossils may be in part due to high winds that kept surface water well-oxygenated while deeper waters were stagnant.  If you need to get out of the wind, head into the visitor center to see fossil fish, turtles, and other species on display.  On the deck outside there is an awesome timeline that traces CO2 levels and life on Earth throughout geologic time.

Best Trail

Take the steep steps up the Historic Quarry Trail to find fish fossils still in the rocks.  There is no shade along the trail, but even in the summer the weather is usually not that hot at 7,000 feet in elevation.  From the picnic area, the 1.5-mile Fossil Lake Trail leads to aspen groves.

Get up close with fossils that stand out against the white bedrock in the NPS museum or on the Historic Quarry Trail.  On private land nearby, you can pay to excavate your own fish fossils that you get to keep.

Yellowstone National Park

Wyoming, Montana, Idaho

Managed by National Park Service

Established 1872

2,221,766 acres

Website: nps.gov/yell

Overview

The geothermal features here inspired the creation of the world’s first official “National Park” in 1872.   Most of Yellowstone is actually a supervolcano where the magma heats up underground water producing 10,000 hot springs, fumaroles, and mudpots on the surface, as well as 300 geysers.  Incredibly, over 50% of the geysers in the world occur within this one park, which is equally famous for its wildlife diversity, including grizzly bears, bison, gray wolves, and elk.

Highlights

Old Faithful geyser, Grand Prismatic Spring, Norris Geyser Basin, Mammoth Hot Springs, Grand Canyon of the Yellowstone, countless waterfalls, wildlife in Lamar Valley, Mt. Washburn, Continental Divide National Scenic Trail

Must-Do Activity

The most famous geyser here is Old Faithful, which can shoot water up to 185 feet in the air.  Since the occurrence of several earthquakes it is no longer as consistent as its name suggests, but its eruptions can be accurately predicted every 60 to 110 minutes throughout the day.  Arrive early to get a seat or take the trail up the nearby hill to watch it from above.  Afterwards, hike the boardwalks through colorful Upper Geyser Basin.

Best Trail

A hike into the Grand Canyon of the Yellowstone on Glacial Boulder Trail is one way to find the solitude lacking at the drive-up overlooks (you should still hike to the Brink of Lower Falls with the crowds).  Instead of staying in the packed campgrounds, consider getting a permit to backpack camp in the canyon.

Instagram-worthy Photo

The trail is steep, but paved down to the Brink of Lower Falls on the Yellowstone River for unforgettable view of the canyon, especially on sunny days when a rainbow appears in the spray.

Peak Season

Summer, but Old Faithful Village can seem busy in the winter with all the snowmobiles during the day.

Hours

Fees

$35 per vehicle or America the Beautiful pass

Road Conditions

Very few roads are not paved, but the majority close for seven months in the winter.

Camping

There are many campgrounds in the park, but they fill up quickly the summer (especially at primitive Slough Creek).  The surrounding National Forests offer campgrounds and dispersed sites as well.  We have enjoyed backpacking at designated campsites in the park with a permit, especially in the Grand Canyon of the Yellowstone.
