The Great Basin is aptly named. Twice the size of Kansas, it stretches from the watersheds of the Columbia and Snake rivers south to that of the Colorado, and from the crests of the Sierra Nevada and southern Cascades eastward to the Wasatch front. The Western explorer John Fremont coined its name in 1845. The rivers and streams of the region that Fremont had seen all ended in sinks, marshes or lakes. None flowed to the Pacific Ocean. He confirmed this on meeting Joseph Walker at Mountain Meadows in Utah. Walker had traveled more of the basin’s western margins, dispelling rumors of a river traversing the Sierra Nevada. Precipitation that falls in the Great Basin stays in the Great Basin; water leaves only as vapor. This is the hydrographic Great Basin.

How else to view the vast region between the Rockies and the Sierra Nevada? Geologists speak of the “Basin and Range Province”, so named for its valleys and the towering ranks of north-south mountain ranges that march across the landscapes of Nevada and edges of adjacent states. Unlike the upthrust Rockies and Sierra Nevada, Earth’s crust in the Great Basin appears to be spreading, to be pulling apart. The tilted escarpments of the Wasatch front are the easternmost evidence of this crustal deformation that has built the Basin and Range Province.

Botanists delimit the Great Basin by the hardy flora that clothes this rugged landscape. Great Basin plants tolerate freezing winters and parched summers, and in the valleys, soils of varying salinity. The so-called Sagebrush Ocean fills many of the basins, as do other shrubs, such as shadscale and greasewood. Upslope, these give way to juniper woodlands, often mixed with piñon pine. This floristic Great Basin reaches eastward to central Utah and the Wasatch front, beyond which trees and other plants of the Rockies make their appearance.

The boundaries of all three concepts for the Great Basin — hydrographic, geologic and floristic — largely coincide. Each recognizes the distinctive attributes of the Great Basin that set it apart from neighboring regions. The Great Basin is readily recognizable to the trained eye, whether looking at satellite images, river courses, or the native plant communities encountered on a simple walk.

Utah at the Smithsonian

Hi, I’m Holly Strand from the Quinney College of Natural Resources at Utah State University.

You don’t have to be in Utah to appreciate some of its treasures. Examples of Utah natural history can be found in museums around the globe. The last time I was in Washington DC, I explored the collections of the Smithsonian Museum of Natural History. There turned out to be a whole lot more Utah stuff than I ever imagined.

Many would consider dinosaurs to be our most illustrious museum export. Indeed a 90-foot long Utah diplodocus is the centerpiece of the museum’s Dinosaur Hall.

Not far away is an amazingly intact Camarasaurus from Utah’s Dinosaur National Monument. Its fossilized bones remained in position for over 150 million years. So beautifully and naturally preserved, it still rests on part of the sandstone block in which it was found.

Only a tiny fraction of the Museum’s collections are on display. The vast majority of its 126 million specimens are in drawers, vaults, and freezers. These items are meticulously cataloged and preserved and they serve as primary reference materials for researchers around the world. I found many 1000s of cataloged items for Utah plants, mammals and birds. Less abundant, there are still 100s of records representing specimens of our amphibians, reptiles and fish.

If you poke around in the collections databases you are sure to find something of interest. I found records of some 300 Utah plant specimens collected by Lester Frank Ward, a botanist who worked for John Wesley Powell on his western expeditions. Powell also contributed to the Smithsonian’s collection of flora and fauna. I found 8 bison skulls and one grass species, but there is probably more.

There is the skull and partial skeleton of a grizzly killed in Logan Canyon. Not Old Ephraim–his skull is here in Utah–but another one killed the year before.

In 1950, a meteorite struck a driveway just a few feet from a Box Elder County woman. A few years later, the meteorite was donated to the Smithsonian. But not before it was enhanced by local schoolchildren using crayons of various colors.

The museum’s mineral collection contains 1000s of Utah specimen, some with very strange names : I found Beaverite, Rabbitite Englishite, Coffinite, Psuedowavellite, Cristobalite, Alunite, Apatite and even Bieberite. As in Justin, I guess.

Anyway, you get the idea. The Smithsonian collections form the largest, most comprehensive natural history collection in the world. And Utah is a prime contributor of both collection items and the stories behind them.

By the way, not only are Utah things in the Smithsonian, but there are also Smithsonian things in Utah.

For example, the Henry Mountains in south central Utah were named after the first Secretary of the Smithsonian Institution Joseph Henry.

Another example is Smithsonite–or zinc carbonate–which was first identified by James Smithson in 1802. The very same Smithson left his fortune to the United States government, directing that it be used to create the Smithsonian Institution. The mineral Smithsonite has been found in Tooele and Washington Counties.

Lastly, there’s Smithsonian Butte. When the Powell Expedition traveled through the Zion area, geologist Edward Dutton named the Butte after the expedition’s most generous sponsor. Smithsonian Butte Road is a designated national backcountry byway, crossing over the Vermilion cliffs between Utah 9 and Utah 59.

The mid-1800s were a transformative period in US history. The bloody Civil War had run its course. Twelve years earlier, the Mexican/American war had forced annexation of a vast territory that stretched from the Rockies to the Pacific Ocean. Across the northern edge of this territory, a transcontinental railroad was planned. An ambitious young geologist, Clarence King, convinced President Lincoln of the need to explore, survey and map the topography, watersheds, geology, mineralogy, flora and fauna of this vast uncharted region. King mustered 20 scientists, technicians and frontiersmen to form his Survey of the 40th Parallel. The Survey team took multiple years to thoroughly explore and map a 100-mile-wide band from Virginia City Nevada to Cheyenne Wyoming.

Among the men was one Sereno Watson, who at 42, found himself disenchanted by his forays into medicine, teaching, farming and banking. Word of the King Survey fired his imagination, so in 1867 he joined the migration west. A barefoot, penniless Sereno Watson found the Survey encamped on the lower Truckee River south of Pyramid Lake. More from pity than need, Clarence King let Watson join as an unpaid assistant. When illness sidelined the Survey’s botanist, Serano Watson eagerly took his place.

King prized Watson for his diligence and enthusiasm. In June of 1869, the Survey staked out what would become a favorite encampment at Parley’s Park north of Park City. From that base, Survey members fanned out to explore the Wasatch Range, the western spurs of the High Uintas, and the Great Salt Lake. Watson added to his plant collections, ultimately pressing 900 specimens, many new to science. He later curated them back at Yale. Watson honored the Survey’s leader by naming new plant species kingii, including a species each of biscuit root, buckwheat, bladderpod, flax, lupine, clover and ragwort. Asa Gray, then the reigning US botanist, honored Sereno in naming Penstemon watsonii, a lovely species discovered by the mining town of Austin Nevada. You can see the striking sky blue flowering spires of this wildflower amid montane meadows from eastern Nevada across central Utah into Colorado, including the vicinity of Parley’s Park.

Thomas Jefferson will forever be remembered as our third president and author of the Declaration of Independence. Jefferson oversaw the acquisition of the vast Louisiana Purchase and soon thereafter initiated planning for an expedition that would be named the “Corps of Discovery”. That bold adventure was led by Meriwether Lewis and William Clark. These two frontiersmen are immortalized by the plants and animals that taxonomists named in their honor.

The arduous 3-year expedition route passed far north of what would become Utah, ascending the tributaries of the Missouri River and later following down the Columbia River to the Pacific Ocean. Jefferson, being an avid naturalist, instructed the explorers to observe and make record of the geography, plants and animals that they encountered and to return with those specimens which they could carry. Hopes for discovery of a navigable inland passage to the Pacific were not realized, but in all other ways, the expedition was a singular success.

Lewis and Clark made collections of pressed plants along the way. These eventually went to Frederick Pursh, a German botanist in Philadelphia. One new genus of plant he named Lewisia. These are the bitteroots, one of which is the spectacular state flower of Montana. Another genus new to science he named Clarkia . Many species names of plants immortalize the men too, such as the blue-flowered flax, Linum lewisii, commonly used today for seeding following wildfire.

Bird names honoring the discoveries of Lewis and Clark include Clark’s nutcracker and Lewis’ woodpecker. Clark’s nutcracker is a big black and gray relative of crows. [https://wildstore.wildsanctuary.com/collections/special-collections, https://wildstore.wildsanctuary.com/collections/special-collections] This noisy resident of Utah’s mountains is notable for its habit of caching seeds of pine trees to be remembered and found months later.

The age of the pioneer naturalist in North America closed more than a century ago, but the names of men like Meriwether Lewis and William Clark live on with the plants and animals that bear their names.
