That photo looks like I-19 in Arizona, America's only metric road (more from Atlas Obscura). Congress passed the Metric Conversion Act in 1975, the last time the US had a serious metric system push, and various tests were carried out to start the conversion process. I-19 in Arizona was one of the test sites. After widespread opposition ("Forcing the ...

Saguaro cactus are native specifically to the Sonoran desert. This photo outlines where the Sonoran desert is located. According to this TripAdvisor thread, you will not see them 20 minutes north of Phoenix. They seem to stop growing above 3,000 feet above sea level. You should be able to see them south of Sedona, along I-17 interstate highway.

You can find Saguaro in South Mountain Park on the south side of Phoenix. Here's a screenshot from Google Street View showing a couple:

The company that owns the crater notes that there are guided rim walks and a few separate lookout points from which you can see the crater. However, it doesn't appear to be possible to walk around on your own. Access to the floor of the crater is not allowed, according to a representative of the company on TripAdvisor: Thank you very much for your inquiry....

You want 1 America the Beautiful Pass. (I don't think there is any such thing as a "US Parks Pass". Your link, usparkpass.com, is just a third-party site selling the same America the Beautiful pass.) If you read the rules for that pass carefully, it says: Allows pass owner and accompanying passengers in a single, private, non-commercial vehicle ...

It's not public in the sense that you can just walk there wherever you want. The crater is owned by a private company, which operates a visitor center and guided tours for a fee. It looks on Google Maps as if the crater itself is also fenced.

Your segment from Palm Springs to Phoenix will probably be along I-10, which passes through Blythe at the Colorado River between Yuma and Lake Havasu City. There will be scattered saguaro all along that stretch of road and more densely populated patches just off the highway, especially to the south-east of Blythe in southern Arizona. When I lived in ...

Local news from August indicates that county, state and federal highways aren't included in the road closure order. The resolution closes Navajo-owned and maintained roads, about 5,000 miles, to outside tourists and visitors. County, state, federal roads aren’t included, but Shorty said that shouldn’t be construed as an invitation for tourism. So you ...

Leaving the Phoenix area to the east along Highway 60, there are many many Saguaro between Apache Junction and Superior. Leaving the Phoenix area to the south along the I-10, once you leave the developed area (not too far south of Chandler), you again can see many of them, and can continue to see many of them all the way until you hit the border of New ...

Appears as though it was a timing situation when it was built, during a brief law change. Gizmodo has an article on it: That made sense in 1980, when I-19's signs first went up and when US was near the peak of its flirtation with the metric system. Five years earlier, President Ford had signed the Metric Conversion Act, declaring the metric system "...

Unfortunately, yes, you will have problems with most large rental car companies. Accident risks for young drivers are significantly higher, so they either avoid the risk completely, or charge an arm and a leg if you are below 25. Your best chances are to browse local companies; consider also companies that are not located at the airport. Paying a taxi to ...

I am guessing you are searching for flights from Tucson (TUS) to Denver (DEN), but you can get much cheaper flights from Phoenix (PHX). I'm seeing round-trip fares PHX-DEN-PHX of $112 (Spirit Airlines, many extra fees likely), $144 (Southwest, includes bags) and $185 (US Airways, bags extra). The difference would probably cover a shuttle from Tucson to PHX ...

On Greyhound I can find one way tickets from Tucson to Denver for 99$. It takes less than 24 hours and has a transfer in Las Cruces, New Mexico. Boulder is in the Denver metropolitan area, so transfer from Denver to Boulder is trivial. I doubt any other mode of transportation is going to systematically beat that, although you may or may not find cheaper ...

Google Maps shows your two proposed routes as having a less than 5 mile and less than 10 minute difference. Which one is "faster" becomes almost entirely irrelevant at that point. So we're left with "more scenic." Of the two routes, one (via Payson) runs almost entirely through Tonto National Forest and Sitgreaves National Forest, while the other (via Globe)...

There is also Ethel M Botanical Cactus Garden 10 miles away from downtown Las Vegas. According to the pictures from Google Maps, there are some big cacti there (I don't know whether they are Saguaro or not). Those cacti are not quite "in the wild", but the question as I stated it does not specify whether I'm looking specifically for cacti in the wild. (In ...

I crossed the Navajo Nation back in June. Decided not to try and cross at dark during the curfew since I figured they didn’t need any extra folks around. No problem driving the roads. Only road block I came across was on the road leading into Monument Valley park. None on the main highways. I stopped at a gas station and was impressed at the care everyone ...

The statement that the cited website is the official website for Antelope Canyon tours is false. I found a list of companies which offer tours to Antelope Canyon (note that the prices listed in the table are not accurate as of today). It looks like one can almost always find availability for any date since there are more than 10 companies organizing tours.

It looks like all the options are annual. The guidance for pass use states: What does the Annual Pass cover? The Annual Pass admits pass owner/s and passengers in a non-commercial vehicle at per-vehicle fee sites; and pass owner + 3 adults, not to exceed 4 adults, where per-person fees are charged. (Children under 16 are always admitted free.) So basically ...

No there isn't. The entry price is 18 $ and there is no other way to visit the crater.

If you're in a canyon or gully and it starts raining hard (> 5 mins), get to higher ground ASAP. This should be obivous, but perhaps not. Most serious trouble from flash flooding come from people camping in a gully and some distance away, the rains come off a mountain in a flood. Preventing this is a bit harder, but still not difficult. Look around for ...

For small memorial plaques and the like, you can consult the American Memorials Directory and the Historical Marker Database, which turn up a handful of memorials. The only one that makes the list of the "Doughboy Center's" list of AEF memorials is the World War I memorial outside the Mohave County Court House in Kingman, Arizona. It has one of only seven ...

The drive on I-17 between Sedona and Phoenix has wonderful views of saguaros from a car, but not places to hike among them. You should definitely stop at the Desert Botanical Garden in Phoenix; they have great specimens and information. The South Mountain Park and Preserve in SW Phoenix has some great hikes with plenty of saguaros. You can't go to Phoenix ...

This isn't answering exactly what you asked, but if you are travelling through Palm Springs, and interested in the unique flora of the American southwest, you should make a side trip to Joshua Tree National Park, home to the a desert plant just as iconic and even more restricted in range than the saguaro.

The hike described on alltrails is only one section of the Rim Trail described in the NPS document. Inspecting the alltrails map, their hike starts at the point that NPS calls "Village Route Transfer", goes east to Mather Point, and then returns the same way. The NPS guide shows the distance from Village Route Transfer to Mather Point as 1.2 + .7 + .7 = 2....

I finally dropped and email to The View hotel (inside Monument Valley). The wildcat trail hike must be completed before the sun goes down. As long as you do that you can stay on it later than 4:30.

You will probably be hard pressed to find World War I memorials or other related sites in the West. You can probably start with the list of World War I memorials of which there are few in the United States and World War I museums which there are still fewer. As far as factories are concerned I would think that most of those would be on the East Coast but ...

Given your scheduling, one option is to drive. Google Maps shows it as a 13 to 13.5 hour drive, all on major highways (i.e. no questionable remote back roads involved). Both Orbitz and Expedia suggest that a one-way car rental from Tucson would cost about $145 including fees. Of course, with a drive that long you might want to stay overnight on the way. That ...

It's technically feasible but unless you want to spend all you time driving with only time to take a picture at each location, maybe drop one. Antelope and Zion are quite far from Las Vegas and would be a long day trip them selves. Even Grand Canyon from Las Vegas is an entire day. There are a number of operators that do guided (by bus) excursions to ...

I'm willing to bet that this sign is from a place close to the Mexican border. I live in San Diego, CA, a city close to the Mexican border, and I've seen a few road signs in my area with metric units (actually, both metric and Customary units). The reason why those metric signs exist is because frequently, people driving on those roads are often tourists ...

There is no single easy way to do this. You will have to construct routes yourself, although websites like Google Maps are certainly going to be useful. (You can use Street View to glean speed limits and pavement condition, for example, although not all areas are updated very often. Some highways in nearby parts of Montana to me haven't been updated in ...
