Boulder Dam Tour / Hoover Dam Tour Confusion

Boulder Dam / Hoover Dam Naming Controversy

During the years of lobbying leading up to the passage of legislation authorizing the dam in 1928, the dam was generally referred to by the press as “Boulder Dam” or “Boulder Canyon Dam”, notwithstanding the fact that the proposed site had been shifted to Black Canyon.[14] The Boulder Canyon Project Act of 1928 (BCPA) never mentions a proposed name or title for the dam. The BCPA merely allows the government to “construct, operate, and maintain a dam and incidental works in the main stream of the Colorado River at Black Canyon or Boulder Canyon”.[105]

When Secretary Wilbur spoke at the ceremony starting the building of the railway between Las Vegas and the dam site on September 17, 1930, he named the dam “Hoover Dam”, citing a tradition of naming dams after Presidents, though none had been so honored during their terms of office. Wilbur justified his choice on the ground that Hoover was “the great engineer whose vision and persistence … has done so much to make [the dam] possible”.[106] One writer complained in response that “the Great Engineer had quickly drained, ditched, and dammed the country”.[106]

After Hoover’s election defeat and the accession of the Roosevelt administration, Secretary Ickes ordered on May 13, 1933 that the dam be referred to as “Boulder Dam”. Ickes stated that Wilbur had been imprudent in naming the structure after a sitting president, that Congress had never ratified his choice, and that it had long been referred to as Boulder Dam.[106]

Boulder Dam and the Hoover Dam Name Change – Secretary Ickes Tried To Retain The Name “Boulder Dam”

When Ickes spoke at the dedication ceremony on September 30, 1935, he was determined, as he recorded in his diary, “to try to nail down for good and all the name Boulder Dam”.[65] At one point in the speech, he spoke the words “Boulder Dam” five times within thirty seconds.[107] Further, he suggested that if the dam were to be named after any one person, it should be for California Senator Hiram Johnson, a lead sponsor of the authorizing legislation.[65] Roosevelt also referred to the dam as “Boulder Dam”,[83] and the Republican-leaning Los Angeles Times, which at the time of Ickes’ name change had run an editorial cartoon showing Ickes ineffectively chipping away at an enormous sign “HOOVER DAM”, reran it showing Roosevelt reinforcing Ickes, but having no greater success.[108]

In the following years, the name “Boulder Dam” failed to fully take hold, with many Americans using the two names interchangeably and mapmakers divided as to what name should be printed. Memories of the Great Depression faded, and Hoover to some extent rehabilitated himself through good works during and after World War II. In 1947, a bill passed both Houses of Congress unanimously restoring the name to “Hoover Dam”. Ickes, who was by then a private citizen, opposed the change, stating, “I didn’t know Hoover was that small a man to take credit for something he had nothing to do with.”[109]

Stormy Zion Park Tour – Part 2

Spring-time Storm at Zion Park, Utah

We were headed to Utah for a tour of Zion National Park, and the weather forecast told us we might expect thunderstorms and rain.

Heading into a spring-time storm
at Zions Park, Utah

I had been watching the clouds over northern Arizona and southern Utah since we left Las Vegas.

As experienced guides, we’ve seen it all, and a little spring-time storm doesn’t stop us.

While we were still 50 miles away from Zion Park, we expected that if it did rain at Zion National Park, it would not rain for long.

Patches of heavy black clouds were being pushed across the desert southwest by the wind at about 20 miles per hour.

We picked up our fresh box lunches and headed for the Zion Park Visitor Center. Before we got off the bus, and the rain began – a heavy soaking drizzle.

We decided to stay on the bus and eat our lunch right then. It was a little earlier than usual, but we were hoping the squall would pass over us quickly.

Fifteen minutes later, still raining, we headed for the visitor center. After exploring the exhibits there, we boarded the Zion Park Shuttle Buses.

The clouds that blew in were now covering some of the mountain peaks, a disappointment for sure, but we were still expecting the clouds to blow over.

While the guests were on the Zion Park Shuttle, I decided I would look for some photo opportunities for the website. I got back in the bus and headed to the Zion Park Museum.

Zion Park Tour from Las Vegas

Photos were a challenge because the clouds covered the mountains much of the time; a little patience paid off.

Our day tour of Zion Park turned out to be great!

By the time we left Zion Park, the rain was gone and a little blue sky was showing between the clouds. The rocks became visible through the mist of the lower clouds as they passed over Zion Canyon and through Zion Valley.

Our guests had a great time, and had the rare opportunity to watch as waterfalls were created before their eyes – ‘flash-floods’ from the rain high in the rock formations of Zion, falling hundreds of feet as a waterfall to become the Virgin River that would eventually flow to the Colorado River.

The guests said they would not have traded this stormy day for any other. They truly appreciated the stop earlier in the day that allowed them to buy light jackets – they were able to get out in the weather and they completely enjoyed their Zion Park tour.

They got to see Zion National Park differently than most other travelers, and they knew it was very special.

Great photos, unusual weather, another great detour through The Great American West!

A Stormy Zion Park Tour – Part 1

Spring-Time Weather – A Storm at Zion Park, Utah

I had a custom tour to Zion National Park scheduled for today, and I always check the weather before picking up my guests.

Rain Ahead, Thunderstorm Expected:

Zion Park, Full-Day Tours from Las Vegas

Spring is here in Zion Park now, and thunderstorms and lightning were expected later today all over the Southwest.

The storm would cover a large area, from the Las Vegas valley to the Grand Canyon and of course, to our destination at Zion in Southern Utah.

The temperature in Zion Park when I checked at 4:30am was 34 degrees, and a high of 48 degrees was expected.

Some guests had flown into Las Vegas from North Carolina and were staying at the Wynn resort on The Strip. They were expecting sunshine and blue skies, which is normal for this time of year.

I warned about the weather, and asked if they wanted to go back to their room for long pants and long-sleeved shirts or a jacket – and they told me they had not brought anything but summer clothes.

The safety and comfort of our guests is important to us, so we added a quick shopping trip for them at our first comfort stop in Mesquite, Nevada. About 10 minutes later they came back to the bus with long pants and light jackets. Good choice.

We followed the rain from Mesquite to St. George (Utah), to Hurricane, and finally Springdale, the gateway to Zion National Park. The desert had been washed clean for us the whole way.

Rain has a remarkable impact on the desert – everything changes.

Rain washes the dust off all the plants, allowing their true colors to be seen – bright and beautiful.

Rain darkens the red and white sandstone, too, and changes the visual character of the desert, really bringing it to life right before your eyes.

Made fresh for our guests.

Anyway, we must have been 30 minutes or so behind the storm, and we thought we would actually miss the rain.

We picked up our freshly-made box lunches from Switchback Grille & Trading Company, one of our favorite restaurants in Springdale (just outside the entrance to Zion), and headed into the park.

Before we got off the bus at the Zion Park Visitor Center, a black cloud scooted over and within minutes, it began to rain.

Was this Zion Park tour going to be a disaster for my guests?
