Nelson (Eldorado Canyon)

Four names, and they are not synonyms

Eldorado Canyon makes a good half-day out of Boulder City: a paved drive into a narrow desert canyon, a small inhabited town at the end of it, a guided trip underground, and a lot of nineteenth-century Nevada in a short distance. Almost everything written about the place trips over the naming, though, so start there.

Eldorado Canyon is the landform — a 22.9-square-mile drainage in the Eldorado Mountains that runs east to the Colorado River, at what is now the upper end of Lake Mohave. The USGS measures it as a basin, because hydrologically that is all it is.

The mining district is the legal entity, and it has collected names the way old districts do. Organized in 1861 under the name Colorado mining district, it later picked up other labels in the geological literature — El Dorado, Eldorado Canyon, Nelson. All four names appear in federal publications, describing the same ground. Nevada’s own state historical marker list files the canyon as Eldorado Canyon, one word, which is the spelling this page follows.

Nelson is the town, up-canyon on NV-165. It is inhabited. Calling it a ghost town is a description of the scenery, not the census.

“Nelson Ghost Town” is a fourth thing again: the trade name of a private visitor compound farther down the highway, built around the Techatticup Mine — a ticketed attraction with its own hours, and for most people the best part of the day out here. The pin on this page is the townsite; the photographs you have probably seen are the mine property, which has its own page and its own booking.

For most visitors that compound is the right way to see this canyon. It puts you underground with someone who knows the rock, in maintained and lighted workings with an operator responsible for them, a short walk from the car. That is a better afternoon than casting around the open desert nearby, where the historic workings are unsecured and the property lines are invisible. Book the tour, and enjoy the rest of the canyon from the road.

What the record does not settle

The origin story is usually told with more confidence than the sources support, and the uncertainty is part of what makes it interesting.

The 1991 USGS mineral survey of the surrounding wilderness study areas lays the disagreement out plainly: credit for the earliest gold and silver strike splits between two candidates in the sources — soldiers from Fort Mohave working the ground that is now the Techatticup mine in 1857, or a find on the Honest Miner claim, today part of the Rand property. Two candidate places, two candidate origins, and the federal compilers declined to choose between them. Other accounts put prospectors here about 1859. What is firm is the institutional date: the district was organized in 1861.

The gap is worse than a disputed year. Almost everything published about the bonanza decade is reconstruction from newspapers, memoirs, and later compilations rather than from the district’s own records, which is also why the money figures never quite reconcile. That argument belongs on the mine’s page, where the numbers are.

The Spanish story — that prospectors from the 1770s worked the canyon and left the name El Dorado — is repeated everywhere, including by tourism agencies. It is a good story and a durable local tradition rather than documented history; neither of the USGS reports cited on this page mentions it.

Half the district is underwater

Miners, prospectors, and mill operators settled the canyon around 1861. In 1867 the Army established Camp Eldorado at the canyon mouth — on land, as the USGS puts it, now beneath the surface of Lake Mohave.

That sentence is the key to the whole site. This district existed where it did because the Colorado River was navigable to here: steamboats brought machinery in and carried ore out, and the mills, the landing, and the river camp were all down at the water. When the reservoir came up behind Davis Dam it drowned that end of the canyon. What survives above water is the upper half of a system whose economic logic was at the bottom — which is why the ruins around Nelson look like a mining camp with no visible reason to be where it is.

September 14, 1974

At about 2:30 in the afternoon, a thunderstorm cell that had been tracking down the drainage — dropping rain and hail at rates up to three inches in half an hour, and intensifying as it moved — put an estimated 76,000 cubic feet per second through the canyon just upstream of the developed area at the mouth. At least nine people were killed. The restaurant was obliterated; nine cabins, five trailer homes, 38 vehicles, 23 boats, 19 boat trailers, and half the boat docks were destroyed. Bodies were recovered from Lake Mohave as much as two and a half miles from the landing, some more than a month later. The National Weather Service notes the facility was never rebuilt, for safety reasons.

Two details from the USGS assessment are worth carrying up the canyon with you.

The first is what the storm did to people’s judgment. Intense rain and hail were falling at the canyon mouth when the flood front arrived, and the report’s plain reading is that this probably caused people to run for shelter or stay put rather than leave the canyon floor. The instinct to get out of the weather is the instinct that kills you in a wash.

The second is the recurrence language. The report is explicit that although the recurrence interval for runoff of that magnitude is long, a similar flood could occur in any given year. This was not the canyon’s first: residents interviewed afterward recalled a large flood in 1904 that wrecked the milling works at the mouth, and another in 1960 that heavily damaged the store and restaurant then operating at the canyon mouth — a similar building to the one 1974 destroyed outright.

The road up the canyon is in the drainage. Nothing about a paved surface changes where the water goes. If there is weather anywhere over the Eldorado Mountains, the correct move is not to be down in the wash, and that holds on a clear day at the mouth — the Park Service’s own guidance for this recreation area is that violent downpours cause flash flooding in distant areas untouched by rain.

The ground you are driving past

The hills around Nelson hold dozens of historic workings, and the ownership is a patchwork of federal land, active mining claims, and private inholdings with no line painted on the ground. The USGS, surveying the wilderness study areas next door, set most claims near its boundary aside as private — the Techatticup among them. A dirt track leaving the highway is not evidence of public access.

The workings themselves are the other half of that. The Park Service has documented over 950 abandoned mine features in Lake Mead National Recreation Area, posts signs near known openings, and states flatly that abandoned mines are usually unsafe and should not be entered. Nevada’s Division of Minerals runs an entire public-awareness program on the same point — shafts, adits, stopes, and pits, unstable with age and often hard to see until you are at the edge. The good news is that the canyon already has the underground visit worth making: the guided tour at the mine is the one way in here, and it is the one you want.

Structures and artifacts on federal land are protected by federal law. The reason to behave that way across the whole canyon, not just the federal parts, is that you cannot see which parcel you are standing on.

Access, services, season

NV-165 leaves US-95 south of Boulder City and runs paved east to Nelson. A passenger car makes the entire corridor. What is not paved — the tracks climbing into the district — is unmaintained, reshaped by every storm, and frequently crossing somebody’s claim.

Beyond what the mine compound has on hand there is no fuel, no water, and no food in the canyon, so stock up in Boulder City or Searchlight — they are the last full services in either direction and both are worth a stop in their own right. The Park Service’s baseline for this desert is at least one gallon of drinking water per person per day, and that is a floor rather than a plan. Summer here is genuinely dangerous rather than merely unpleasant; October through April is the season to come, and the light is better then besides. Check Nevada DOT’s NVROADS for highway conditions before you set out.

Around it

The nearest entries are listed below. Further out, the same corridor gives you Hoover Dam — the federal river project that ended the era this canyon belonged to — plus Christmas Tree Pass and the Grapevine Canyon petroglyphs an hour south. For more of the same century of Nevada, Goodsprings, Potosi, and Saint Thomas are the other Clark County entries worth the drive. Everything in the county is at Clark County, Nevada, the rest of the state’s camps at Nevada ghost towns, and all of it on the map.
