Joshua Tree National Park!
Correct!
Joshua Tree National Park is the answer. (Map link:

Allow me to explain the hints in the original riddle:
collinsmark said:
This park's namesake is a twisted, spiky organism that, of the Agave family, looks like it did not exit a Dr. Seuss book. (Until recently, it was considered a giant member of the Lily family, but DNA studies in a red hill mining town led to the divisions in god's country.) Look where mothers of the disappeared are running to stand still with or without you. Trip through your wires to get to bullet, the blue sky, before reaching one tree hill. And I still haven't found what I'm looking for.
Please include a map link (or at least some coordinates or something to indicate the location) of the park. If you insist on indicating a particular building where the streets have no name, any building within the park will be accepted.
Here is a description of the Joshua Tree [organism] from the park's own website (
https://www.nps.gov/jotr/learn/nature/jtrees.htm):
Surrounded by twisted, spiky trees straight out of a Dr. Seuss book, you might begin to question your map. Where are we anyway? In wonder, the traveler pulls over for a snapshot of this prickly oddity; the naturalist reaches for a botanical guide to explain this vegetative spectacle; and the rock climber shouts “Yowch!” when poked by dagger-like spines on the way to the 5.10 climbing route.
Known as the park namesake, the Joshua tree, Yucca brevifolia, is a member of the Agave family. (Until recently, it was considered a giant member of the Lily family, but DNA studies led to the division of that formerly huge family into 40 distinct plant families.)
The other big hint:
Yes, as
@Jonathan Scott hinted at, there is U2 album with the name "The Joshua Tree." If you don't know, The Joshua Tree National Park is a desert park, really. Here is a quote from the
U2 Album's wiki page:
Band manager Paul McGuinness recounted that
The Joshua Tree originated from the band's "great romance" with the United States, as the group had toured the country for up to five months per year in the first half of the 1980s.
[1] Leading up to the album sessions, lead vocalist
Bono had been reading the works of American writers such as
Norman Mailer,
Flannery O'Connor, and
Raymond Carver so as to understand, in the words of
Hot Press editor
Niall Stokes, "those on the fringes of the promised land, cut off from the American dream".
[3] Following a 1985 humanitarian visit to
Ethiopia with his wife
Ali, Bono said, "Spending time in Africa and seeing people in the pits of poverty, I still saw a very strong spirit in the people, a richness of spirit I didn't see when I came home... I saw the spoiled child of the Western world. I started thinking, 'They may have a physical desert, but we've got other kinds of deserts.' And that's what attracted me to the desert as a symbol of some sort."

The studio album contains the following songs:
I think I was able to fit them all in the riddle.
Okay,
@tionis, you are up, unless you wish for somebody else to go instead.
The upside was, the airbags didn't go off and I was able to drive it home
Over to you.
