Major Powell – Colorado River Steamship

The Major Powell was a small experimental twin-screw steam launch built and launched in 1891 at Green River, Utah, on the Green River. It was named for Major John Wesley Powell, the one-armed Civil War veteran and explorer who led the first scientific boat expeditions down the Green and Colorado Rivers in 1869 and 1871–72.

It was owned and operated by the Green Grand & Colorado River Navigation Company (headed by B. S. Ross). The company’s goal was to establish excursion steamers carrying tourists from the Denver & Rio Grande railroad at Green River, Utah, down the Green River to its confluence with the Colorado (then often still called the Grand) and a short distance into Cataract Canyon, with plans for a hotel near the head of the cataracts.

Build and Design Principles

The vessel measured about 35 feet in length, 8 feet in beam (some accounts note 8–10 feet), with a draft of roughly 26 inches and a capacity of about 3 tons. It featured an open deck covered by a canvas canopy. Propulsion came from two 6-horsepower coal-fired steam engines, each driving one of a pair of twin screws (propellers).

Design priorities reflected the harsh realities of the upper Green and Colorado Rivers in the canyon country:

  • Shallow draft to handle low water, sandbars, and rocky channels.
  • Twin-screw propulsion for better maneuverability in narrow, winding canyons and against variable currents, rather than traditional paddlewheels (more common on the lower Colorado).
  • Compact size and light construction suitable for assembly after rail shipment and operation in remote, undeveloped terrain.
  • Open-deck simplicity for excursion passengers rather than heavy freight capacity.
  • Protective adaptations after early problems: iron guards were added to the screws after rocks damaged the propellers on the first trial run in fast, shallow water. The boiler was later converted from coal to wood (local cottonwood) because coal was scarce and heavy to transport in the canyons.

These choices made it a practical prototype for testing commercial steam navigation in an environment far more challenging than the lower Colorado River (where larger sternwheelers had operated for decades hauling freight and passengers between the Gulf of California and points upstream toward present-day Lake Mead). The Major Powell was underpowered for strong upstream currents and required constant attention to fuel and channel conditions.

Operational History

Launched in August 1891, the boat’s first trial was unsuccessful due to propeller damage. After the iron guards were fitted, its first successful voyage began around April 15, 1892, under the command of local rancher Arthur Wheeler (with a small crew). It descended the Green River through Labyrinth and Stillwater Canyons to the confluence and a short distance down the Colorado to the first cataract at the head of Cataract Canyon. Returning upstream proved difficult: the underpowered engines struggled against the current, coal ran low, and the boat was tied up at Wheeler’s ranch (about 22 miles below Green River). The crew walked overland to announce the success in town on July 3, 1892.

A second voyage followed after the conversion to wood fuel. The round-trip river time between the ranch and the first cataract was only about four days, but the full expedition took roughly a month because of the labor of cutting and loading cottonwood. Later accounts also describe additional trial or excursion efforts into 1893.

Despite these limited successes, the boat was dismantled in 1894 for its machinery (reportedly used in a wrecking plant at Green River). The hull was left behind and washed away in a subsequent flood.

Role in Expanding Trade Along the Colorado River

The Major Powell played only a minor and ultimately unsuccessful role in commercial development. Its purpose was primarily tourism and excursion traffic rather than freight or bulk trade. The company hoped to open a scenic passenger route linked to the railroad, but the combination of underpowered engines, fuel logistics, shifting channels, sandbars, and the formidable cataracts prevented sustained commercial service.

On the broader Colorado River system, steam navigation had already been established decades earlier on the lower river (from the mouth near the Gulf of California upstream past Yuma and toward the Mohave region). There, larger shallow-draft sternwheelers carried significant freight (supplies, mining equipment, goods) and passengers, supporting settlement, mining, and military posts until railroads largely displaced them. The upper Green and Colorado canyons remained far more difficult; the Major Powell was among the earliest (and essentially experimental) attempts to apply steam power there. It demonstrated that limited powered travel was possible under favorable conditions but did not lead to a viable trade route or fleet of excursion steamers. Subsequent upper-river boats in the early 20th century (such as the Undine, Cliff Dweller, and others) similarly struggled and left no lasting commercial impact before railroads, roads, and later dams transformed the region.

In short, the Major Powell stands as a short-lived technological and promotional experiment—an ambitious but underpowered effort to commercialize the scenic upper canyons that John Wesley Powell had first explored by rowboat a generation earlier. It highlighted both the possibilities and the severe practical limits of steam navigation on those waters.

Cliff Dweller – Colorado River Steamship

The Cliff Dweller was a stern-wheel steamboat that operated briefly on the Green River (a major tributary of the upper Colorado River) in Utah in the early 20th century. It belonged to a short-lived series of experimental vessels attempting commercial navigation on the challenging upper Colorado/Green River system, far upstream from the better-known lower Colorado River steamboat fleet that served Yuma, mining districts, and points north into the late 19th and early 20th centuries.

Origins and Construction

The vessel began as the City of Moab, a gasoline-powered, screw-driven boat. In 1905–1906, owner John J. Lumsden (with involvement from Charles Anderson and others) had it substantially rebuilt at Halverson’s (near Green River, Utah). Workers removed the upper works and tunnels, lengthened the hull by about 10 feet, and converted it to a coal-fired stern-wheeler with steam power (two stern-wheel engines, each rated around 25 horsepower in some accounts). It was renamed the Cliff Dweller, likely referencing the prehistoric Ancestral Puebloan (cliff-dweller) ruins and landscape along the river canyons.

It was launched around November 1905 at Halverson’s. Contemporary descriptions and later lists give approximate dimensions of 70 feet in length and 20 feet in beam, with a very shallow draft of about 14 inches (light; around 16–20 inches or more when loaded with fuel such as coal). These shallow-draft characteristics were essential for the sandbars, riffles, and variable water levels of the Green River.

Role Along the Colorado River System

Unlike the commercial stern-wheelers of the lower Colorado (such as the Mohave, Gila, Cocopah, and others operated by George A. Johnson & Company and later the Colorado Steam Navigation Company), the Cliff Dweller was an upper-river experiment. Its intended purpose was commercial service—primarily linking Green River, Utah, with Moab and points toward the confluence of the Green and Grand (upper Colorado) Rivers—for freight, passengers, or related trade. The upper river was far more difficult than the lower reaches due to rapids, sandbars, fluctuating flows, and limited traffic potential.

In practice, the boat made only limited use. Its principal documented voyage occurred in August 1906 under master/pilot C. W. Anderson (with H. T. Yokey as chief engineer and a small crew that included firemen, deck officers, and a cook). The log records a cruise from Green River downstream toward the junction of the Green and Grand Rivers (reaching Valentine’s Bottom, about 20 miles from the confluence, and visiting sites such as cliff dwellings and the Cave of Winds). The return upstream involved the usual hazards: grounding on sandbars (including at Hell’s Hole and Brigham’s Aleck), the need to use a capstan or shore lines, and temporarily raising engines when the paddle wheel struck bottom. The trip carried guests rather than commercial cargo and demonstrated the difficulties of sustained operation. It made one main long trip plus a couple of shorter side trips.

These upper-river efforts (including earlier vessels such as the Undine and later ones such as the Black Eagle and Charles H. Spencer) were generally short-lived and commercially unsuccessful because of the river’s obstacles and the lack of sufficient traffic once railroads expanded.

Specifications (Approximate, from contemporary and compiled sources)

  • Type: Stern-wheel steamboat (converted from gasoline screw propulsion)
  • Length: ~70 feet (after lengthening from the earlier City of Moab configuration)
  • Beam: ~20 feet
  • Draft: ~14 inches light; higher when loaded (e.g., with coal)
  • Propulsion: Coal-fired steam; stern-wheel engines
  • Built/rebuilt: Halverson’s, Utah, 1905 (rebuild completed for 1906 operation)
  • Owner: Primarily John J. Lumsden (with partners at times)

Exact tonnage and full engine details are sparsely recorded compared with the lower-river fleet.

Ultimate Fate

Commercial prospects between Green River and Moab proved unviable; operators concluded the venture could not generate adequate revenue. In 1907 (accounts cite April), Lumsden sold an interest, and the boat was cut in two, shipped overland to Salt Lake City, and placed in service as an excursion vessel on the Great Salt Lake. It was renamed the Vista and operated as a tourist craft for a number of years.

The Cliff Dweller thus represents one of the more ambitious but ultimately unsuccessful attempts to extend steam navigation into the upper Colorado River basin. Its brief career illustrates both the engineering adaptations required for shallow, obstructed western rivers and the limits of steamboat economics once railroads and other transport options became available. Primary details come from contemporary logs, testimony in later legal proceedings related to river navigation, photographic records, and compiled steamboat lists (including those drawing on Richard E. Lingenfelter’s research on Colorado River steamboats).

Comet – Colorado River Steamship

The Comet was a small sternwheel steamboat (paddlewheeler) that operated briefly in 1908 on the upper Green River, a major tributary of the Colorado River system, between Green River, Wyoming, and Linwood, Utah.

It was part of short-lived early 20th-century attempts to establish powered commercial navigation on the upper Green and Colorado rivers (in contrast to the longer, more successful steamboat era on the lower Colorado from the Gulf of California upstream to the Virgin River, roughly 1852–1916). These upper-river efforts faced severe challenges from low water, sandbars, swift currents, rocks, and rapids, and most vessels had very short careers.

Construction and Specifications

The Comet was built in Green River, Wyoming, by Holger (also referred to as Marius N. or Holger) Larsen and launched in July 1908 as the flagship of the newly formed Green River Navigation Company. Construction cost about $25,000. Steam engines were sourced from Chicago.

Key specifications (from contemporary lists of Colorado River system steamboats):

  • Type: Sternwheeler (stern-wheel paddle steamer).
  • Length: 60 feet.
  • Beam: 12 feet (one secondary compilation lists 20 feet; primary list data favors 12 feet).
  • Propulsion/engines: Coal-fired, two 20 hp engines.
  • Other: Shallow-draft design intended for the river’s variable conditions; cargo and passenger capacity is not precisely recorded in surviving summaries but was modest, suited to local freight and passengers rather than heavy bulk trade.

It represented an early shift on the upper Green from oar-powered craft to steam power.

Role Along the River

The Green River Navigation Company aimed to carry freight and passengers between Green River, Wyoming (a railroad town), and ranches downstream as far as Linwood, Utah (at the confluence of the Green with Henry’s Fork). This would have reduced reliance on overland freight and supported isolated ranches and communities.

Its maiden voyage was celebrated as a major local event tied to the Fourth of July 1908 festivities. It departed Green River for Linwood (accounts vary slightly on exact departure timing around July 4–7). The downstream leg was relatively successful (one report notes about eight hours), but the return trip proved disastrous: it took roughly 33 hours and was plagued by low water, sandbars, strong currents, and rocks. Passengers and crew repeatedly had to unload the boat and manually haul it past obstacles; fuel shortages forced stops at ranches for more coal.

Only a few trips were completed before operations ceased. The venture quickly proved impractical for regular commercial service.

Ultimate Fate

After its limited runs in 1908, the Comet was abandoned in the Green River a few hundred yards downstream from Green River, Wyoming (near the later site of the Highway 530 bridge area). Portions of the hull remained visible at low water for years afterward. Its bell was later salvaged and used by the local Rotary Club. A historical marker in Green River’s Island Park (Expedition Island area) commemorates the vessel and this brief chapter of river history.

The Comet’s failure mirrored other upper Green/Colorado experiments (such as the Major Powell, Undine, Cliff Dweller, Black Eagle, and Charles H. Spencer), which were similarly short-lived due to the river’s difficulties. Commercial steamboating never became viable on this stretch, unlike the lower Colorado, where vessels supported military posts, mining, and settlement until railroads and dams (notably Laguna Dam) ended the era.

Black Eagle – Colorado River Steamship

The Black Eagle was a small, experimental screw-propelled steamboat built and operated briefly in 1907 on the Green River (a major tributary of the Colorado River) near Green River, Utah.

Description

It was a modest wooden vessel designed for the shallow, variable conditions of the upper Colorado River system’s desert canyons and channels. Key specifications include:

  • Length: approximately 40 feet
  • Beam: 6 feet
  • Draft: 7–8 inches (extremely shallow, allowing it to navigate very low water)
  • Propulsion: screw (propeller) driven by a 20-horsepower compound vertical marine steam engine
  • Fuel: wood or coal
  • Builder/Owner/Operator: Harry T. Yokey (also referred to as H.T. Yokey), a local resident of the Green River/Elgin, Utah, area who experimented with various boats on the river starting around 1902–1903.

Contemporary recollections describe it as significantly smaller than contemporaneous vessels like the sternwheeler Cliff Dweller (about 70 feet long). It was launched in June 1907 just above the railroad bridge at Green River, Utah. One local account notes a man firing the boiler while the boat crossed the river on an upstream angle for roughly half a mile, with the vessel otherwise tied up along the shore.

Its shallow draft and relatively light construction suited exploratory or recreational use on a river known for sandbars, riffles, fluctuating flows, and difficult channels rather than sustained commercial traffic.

History of Usage

Harry T. Yokey, who lived in the Green River area from about 1903 and later retired there, built and ran multiple power boats on the Green River primarily for personal experimentation, testing navigability, and hunting trips rather than commercial freight or passenger service. He had earlier experience with rowboats (including a 1903 hunting trip down toward the cataracts) and other power craft, including involvement with vessels later associated with the Cliff Dweller/City of Moab lineage.

The Black Eagle was his largest boat. In 1907 it made one documented downstream trip of roughly 100 miles. During or after this run the boiler tubes blew out (the vessel is recorded as having “exploded” in 1907 in standard lists of Colorado River system steamboats). The engine and boiler were salvaged, and the hull was abandoned.

Yokey’s overall efforts, including the short career of the Black Eagle, underscored the practical difficulties of power navigation on this stretch of the Green River (between Green River, Utah, and Moab). Channels were hard to follow, sandbars and low water were persistent obstacles, and the river proved unsuitable for reliable commercial steamboat service in that era. By the time of later testimony, no power boats remained operating from Green River, Utah.

The Black Eagle belongs to the short-lived and largely unsuccessful chapter of steamboat attempts on the Green and upper Colorado Rivers in the late 19th and early 20th centuries (alongside vessels such as the Major Powell, Undine, Cliff Dweller, Comet, and Charles H. Spencer). These efforts contrasted with the more extensive commercial paddlewheel operations on the lower Colorado River from the 1850s into the early 1900s. Primary documentation comes from contemporary lists of Colorado River steamboats and from testimony and recollections preserved in Utah historical collections related to river navigation and water rights cases.

In summary, the Black Eagle was a brief, small-scale experimental craft that illustrated both the ingenuity of local river runners and the severe limitations of steam navigation on the upper Colorado system’s tributaries.

White Rim Trail

The White Rim Trail is Canyonlands National Park is a 100 mile back country 4×4 trail that follows an strata of white lime stone along the edge of Island in the Sky mesa Located in Canyonlands National Park, Utah.  Back country permits are required for this trail, and although it can easily be taken in one day, the wise traveler takes their time and runs the route in several days and nights.  There are several camp grounds offering star gazing opportunities, and the grand vistas and long light in the early morning and late afternoon will inspire the Ansel Adams within you.

Once down on the bottom, the well marked Shafer Trail continues on, while the White Rim Trail branches right and to the south.  All along the backcountry dirt road there are numerous spur trails, vistas, and points of interest give you much to explore including Lathrop Canyon, Musselman Arch, Washer Woman Arch and the Monster Tower.  The entire route is easy to follow, well maintained, well traveled and pure joy to run.

The trail winds along a layer of erroded light colored sandstone called the White Rim which undulates around several smaller side canyons which lead down the the Colorado River.  

Available Campsites

There are several small primitive campsites throughout the route.

White Rim Trail

The White Rim Trail is a renowned 100-mile loop through Canyonlands National Park’s Island in the Sky district, offering a bucket-list adventure for overlanders, mountain bikers, and 4×4 enthusiasts. This rugged, high-clearance 4×4 route circumnavigates the Island in the Sky mesa, winding along the “white rim” ledge between the mesa top and the Green and Colorado Rivers below. The trail showcases breathtaking vistas of red rock canyons, towering buttes (like Airport Tower, Monster Tower, and Junction Butte), and the rivers’ confluence, rivaling views from the Grand Canyon’s South Rim. Key highlights include Gooseneck Overlook, Musselman Arch, White Crack (with views of the Maze and Needles districts), and Murphy Hogback, which offers 360-degree panoramas.

The trail features a mix of wide dirt roads, sandy patches, and technical jeep trails with some cliff exposure, particularly at Shafer Trail, Lathrop Canyon Road, Murphy Hogback, Hardscrabble Hill, and Mineral Bottom switchbacks. It’s moderately difficult for vehicles and challenging for mountain bikes, with an elevation gain of approximately 9,160 feet. The route can be driven clockwise (starting at Shafer Trail) or counterclockwise (starting at Mineral Bottom Road), typically taking 2-3 days to complete, though hardcore cyclists may attempt it in one day. Permits are required for both day-use and overnight trips, with 20 designated campsites across 10 camping areas, including Airport Campground. No potable water is available, and high water on the Green River (May-June) can flood western sections, making a full loop impossible. The best seasons are spring (March-May) and fall (September-November) due to milder temperatures and more predictable weather, as summer is extremely hot and winter may bring closures.
